OASIS PETROLEUM INC.

Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Organization and Operations of the Company

Organization

Oasis Petroleum Inc. (“Oasis” or the “Company”) was formed on February 25, 2010, pursuant to the laws of the State of Delaware, to become a publicly traded entity and the parent company of Oasis Petroleum LLC, the Company’s predecessor. Oasis Petroleum LLC was formed as a Delaware limited liability company on February 26, 2007 by certain members of the Company’s senior management team and through investments made by Oasis Petroleum Management LLC (“OPM”) and certain private equity funds managed by EnCap Investments L.P. (“EnCap”). OPM, a Delaware limited liability company, was formed in February 2007 to allow Company employees to become indirect investors in Oasis Petroleum LLC. In May 2007, the Company formed Oasis Petroleum North America LLC (“OPNA”), a Delaware limited liability company, to conduct the domestic oil and natural gas exploration and production activities of the Company. In April 2008, the Company formed Oasis Petroleum International LLC (“OPI”), a Delaware limited liability company, to conduct business development activities outside of the United States of America. In June 2011, the Company formed Oasis Well Services LLC (“OWS”), a Delaware limited liability company, to provide well services to OPNA. OWS and OPI currently have no business activities or material assets.

A corporate reorganization occurred concurrently with the completion of the Company’s initial public offering (“IPO”) of its common stock on June 22, 2010. The Company sold 30,370,000 shares and OAS Holding Company LLC (“OAS Holdco”), the selling stockholder, sold 17,930,000 shares of the Company’s common stock, in each case, at $14.00 per share. After deducting underwriting discounts and commissions of approximately $25.5 million, the Company received net proceeds of $399.7 million. The selling stockholder received aggregate net proceeds of approximately $236.0 million. The Company did not receive any proceeds from the sale of the shares by OAS Holdco. As a part of this corporate reorganization, the Company acquired all of the outstanding membership interests in Oasis Petroleum LLC in exchange for shares of the Company’s common stock. The Company’s business continues to be conducted through Oasis Petroleum LLC, as a wholly owned subsidiary.

Nature of Business

The Company is an independent exploration and production company focused on the acquisition and development of unconventional oil and natural gas resources primarily in the Williston Basin. The Company’s assets, which consist of proved and unproved oil and natural gas properties, are located primarily in the Montana and North Dakota areas of the Williston Basin and are owned by OPNA.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements of the Company include the accounts of Oasis and its wholly owned subsidiaries: Oasis Petroleum LLC, OPNA, OPI and OWS. The accompanying condensed consolidated financial statements of the Company have not been audited by the Company’s independent registered public accounting firm, except that the condensed consolidated balance sheet at December 31, 2010 is derived from audited financial statements. All significant intercompany transactions have been eliminated in consolidation. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation have been included. In preparing the accompanying condensed consolidated financial statements, management has made certain estimates and assumptions that affect reported amounts in the condensed consolidated financial statements and disclosures of contingencies. Actual results may differ from those estimates. The results for interim periods are not necessarily indicative of annual results.

These interim financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain disclosures have been condensed or omitted from these financial statements. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete consolidated financial statements and should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 (“2010 Annual Report”).

The Condensed Consolidated Statement of Cash Flows for the three months ended March 31, 2011 contained an understatement of net cash provided by operating activities and net cash used in investing activities of $3.4 million. This misstatement was a result of management reclassifying changes associated with capital expenditure accrual amounts, included in working capital accounts, from operating cash flows to capital expenditures in investing cash flows. Management of the Company concluded that the misstatement was not material to the three months ended March 31, 2011, and as such, corrected the misstatement during preparation of this Quarterly Report on Form 10-Q. There was no impact on the condensed consolidated balance sheet or condensed consolidated statement of operations for the three months ended March 31, 2011.

Cash Equivalents and Short-Term Investments

The Company invests in certain money market funds, commercial paper and time deposits, all of which are stated at fair value. The Company classifies all such investments with original maturity dates less than 90 days as cash equivalents. The Company classifies all such investments with original maturity dates greater than 90 days as held-to-maturity securities based on management’s intentions to hold the investments to their maturity date.

Treasury Stock

Treasury stock shares represent shares withheld by the Company to pay tax withholding obligations of certain employees upon the vesting of restricted stock awards. These shares are not part of a publicly announced program to repurchase shares of the Company’s common stock and are accounted for at cost. The Company does not have a publicly announced program to repurchase shares of common stock.

Capitalized Interest

The Company capitalizes a portion of its interest expense incurred on its outstanding debt. The amount capitalized is determined by multiplying the capitalization rate by the average amount of eligible accumulated capital expenditures and is limited to actual interest costs incurred during the period. The accumulated capital expenditures included in the capitalization of interest calculation begin when the first costs are incurred and end when the asset is either placed into production or written off.

Recent Accounting Pronouncements

Fair value . In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (“ASU 2011-04”). ASU 2011-04 changes some fair value measurement principles under U.S. GAAP, including a change in the valuation premise and the application of premiums and discounts. It also contains some new disclosure requirements under U.S. GAAP. It is effective for interim and annual periods beginning after December 15, 2011. The Company does not expect the adoption of this new guidance to have a significant impact on its financial position, cash flows or results of operations.

Comprehensive income . In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (“ASU 2011-05”), which provides an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. It does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. ASU 2011-05 is effective for interim and annual periods beginning after December 15, 2011 and will be applied retrospectively. The Company does not expect the adoption of this new guidance to have any impact on its financial position, cash flows or results of operations.

As a result of expiring unproved property leases, the Company recorded non-cash impairment charges on its unproved oil and gas properties of $1.5 million and $2.9 million for the three and six months ended June 30, 2011, respectively, and $7.9 million and $11.0 million for the three and six months ended June 30, 2010, respectively. No impairment charges on proved oil and natural gas properties were recorded for the three and six months ended June 30, 2011 or 2010.

5. Fair Value Measurements

The Company adopted the Financial Accounting Standard Board’s (“FASB”) authoritative guidance on fair value measurements effective January 1, 2008 for financial assets and liabilities and effective January 1, 2009 for non-financial assets and liabilities. The Company’s financial assets and liabilities are measured at fair value on a recurring basis. The Company recognizes its non-financial assets and liabilities, such as asset retirement obligations and proved oil and natural gas properties upon impairment, at fair value on a non-recurring basis.

As defined in the authoritative guidance, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (“exit price”). To estimate fair value, the Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable.

The authoritative guidance establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (“Level 1” measurements) and the lowest priority to unobservable inputs (“Level 3” measurements). The three levels of the fair value hierarchy are as follows:

Level 1 — Unadjusted quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 — Pricing inputs, other than unadjusted quoted prices in active markets included in Level 1, are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, and can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Level 3 — Pricing inputs are generally less observable from objective sources, requiring internally developed valuation methodologies that result in management’s best estimate of fair value.

As required, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The following tables set forth by level within the fair value hierarchy the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis:


	At fair value as of June 30, 2011
	Level 1		Level 2		Level 3			Total
	(In thousands)
Assets (liabilities):
Money market funds	$	215,256	$	—	$	—		$	215,256
Commodity derivative instruments (Note 6)	$	—	$	—	$	(9,953	)	$	(9,953	)

Total	$	215,256	$	—	$	(9,953	)	$	205,303


	At fair value as of December 31, 2010
	Level 1		Level 2		Level 3			Total
	(In thousands)
Assets (liabilities):
Commodity derivative instruments (Note 6)	$	—	$	—	$	(10,486	)	$	(10,486	)

Total	$	—	$	—	$	(10,486	)	$	(10,486	)

The Level 1 instruments presented in the table above consist of money market funds included in Cash and cash equivalents on the Company’s Condensed Consolidated Balance Sheet at June 30, 2011. The Company’s money market funds represent cash equivalents backed by the assets of banks and other liquid securities each with a minimum credit rating of A1/P1. The Company identified the money market funds as Level 1 instruments due to the fact that the money market funds have daily liquidity, quoted prices for the underlying investments can be obtained and there are active markets for the underlying investments.

The Level 3 instruments presented in the tables above consist of oil collars. The fair value of the Company’s oil collars is based upon mark-to-market valuation reports provided by its counterparties for monthly settlement purposes to determine the valuation of its derivative instruments. The Company has a third-party reviewer evaluate other readily available market prices for its derivative contracts as there is an active market for these contracts. However, the Company does not have access to the specific valuation models used by its counterparties or third party reviewer. The determination of the fair value of the Company’s oil collars also incorporates a credit adjustment for non-performance risk. The Company calculates the credit adjustment for derivatives in an asset position using current credit default swap values for each counterparty. The credit adjustment for derivatives in a liability position is based on the Company’s current cost of prime based borrowings (prime rate and associated margin effect). Based on these calculations, the Company recorded a reduction to the fair value of its derivative instruments in the amount of $0.4 million and $0.3 million at June 30, 2011 and December 31, 2010, respectively.

The following table presents a reconciliation of the changes in fair value of the financial assets and liabilities classified as Level 3 in the fair value hierarchy for the periods presented.


	2011			2010
	(In thousands)
Balance as of January 1	$	(10,486	)	$	(2,953	)

Included in other comprehensive income		—			—
Settlements		4,652			59

Balance as of June 30	$	(9,953	)	$	55

Change in unrealized gains included in earnings relating to derivatives still held at June 30	$	533		$	3,008

At June 30, 2011, the Company’s financial instruments, including certain cash and cash equivalents, short-term investments, accounts receivable and accounts payable, are carried at cost, which approximates fair value due to the short-term maturity of these instruments. The carrying amount of the Company’s long-term debt reported in the Condensed Consolidated Balance Sheet at June 30, 2011 is $400.0 million, which approximates fair value.

Nonfinancial Assets and Liabilities

Asset Retirement Obligations — The carrying amount of the Company’s asset retirement obligations (“ARO”) in the Condensed Consolidated Balance Sheet at June 30, 2011 is $10.0 million (see Note 8 — Asset Retirement Obligations). The Company determines the ARO by calculating the present value of estimated cash flows related to the liability. Estimating the future ARO requires management to make estimates and judgments regarding timing and existence of a liability, as well as what constitutes adequate restoration. Inherent in the fair value calculation are numerous assumptions and judgments, including the ultimate costs, inflation factors, credit adjusted discount rates, timing of settlement and changes in the legal, regulatory, environmental and political environments. These assumptions represent Level 3 inputs. To the extent future revisions to these assumptions impact the fair value of the existing ARO liability, a corresponding adjustment is made to the related asset.

Impairment — The Company reviews its proved oil and natural gas properties for impairment whenever events and circumstances indicate that a decline in the recoverability of their carrying value may have occurred. The Company estimates the expected undiscounted future cash flows of its oil and natural gas properties and compares such undiscounted future cash flows to the carrying amount of the oil and natural gas properties to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, the Company will adjust the carrying amount of the oil and natural gas properties to fair value. The factors used to determine fair value are subject to management’s judgment and expertise and include, but are not limited to, recent sales prices of comparable properties, the present value of future cash flows, net of estimated operating and development costs using estimates of proved reserves, future commodity pricing, future production estimates, anticipated capital expenditures and various discount rates commensurate with the risk and current market conditions associated with realizing the expected cash flows projected. These assumptions represent Level 3 inputs. No impairment charges on proved oil and natural gas properties were recorded for the three and six months ended June 30, 2011 or 2010.

6. Derivative Instruments

The Company utilizes derivative financial instruments to manage risks related to changes in oil prices. As of June 30, 2011, the Company utilized two-way and three-way collar options to reduce the volatility of oil prices on a significant portion of the Company’s future expected oil production. All derivative instruments are recorded on the balance sheet as either assets or liabilities measured at fair value (see Note 5 — Fair Value Measurements). Derivative assets and liabilities arising from the Company’s derivative contracts with the same counterparty are also reported on a net basis, as all counterparty contracts provide for net settlement. The Company has

not designated any derivative instruments as hedges for accounting purposes and does not enter into such instruments for speculative trading purposes. If a derivative does not qualify as a hedge or is not designated as a hedge, the changes in fair value, both realized and unrealized, are recognized in the Other Income (Expense) section of the Condensed Consolidated Statement of Operations as a gain or loss on derivative instruments. The Company’s cash flow is only impacted when the actual settlements under the derivative contracts result in making or receiving a payment to or from the counterparty. These cash settlements are reflected as investing activities in the Company’s Condensed Consolidated Statement of Cash Flows.

As of June 30, 2011, the Company had the following outstanding commodity derivative instruments, all of which settle monthly based on the West Texas Intermediate crude oil index price:


		Total
		Notional		Average
Settlement	Derivative	Amount of		Sub-Floor		Average		Average		Fair Value Asset

7. Long-Term Debt

Senior Secured Revolving Line of Credit — The Company entered into its fourth amendment to its amended and restated credit agreement (the “Amended Credit Facility”) on June 16, 2011. The Amended Credit Facility provides for a senior secured revolving line of credit of up to $600.0 million and matures on February 26, 2015. Borrowings under the Amended Credit Facility are collateralized by perfected first priority liens and security interests on substantially all of the Company’s assets, including mortgage liens on oil and natural gas properties having at least 80% of the reserve value as determined by reserve reports.

Availability under the Amended Credit Facility is restricted to the borrowing base, which is subject to semi-annual redeterminations on April 1 and October 1 of each year. On January 21, 2011, a redetermination of the borrowing base under the Company’s Amended Credit Facility was completed, at the request of the Company, in lieu of the April 1, 2011 redetermination. As a result of this redetermination, the Company’s borrowing base increased from $120 million to $150 million, and was then automatically decreased to $137.5 million in connection with the issuance of the Company’s private placement of $400.0 million of senior unsecured notes due 2019 on February 2, 2011 (discussed below).

Borrowings under the Amended Credit Facility are subject to varying rates of interest based on (1) the total outstanding borrowings (including the value of all outstanding letters of credit) in relation to the borrowing base and (2) whether the loan is a London Interbank Offered Rate (“LIBOR”) loan or a bank prime interest rate loan (defined in the Amended Credit Facility as an Alternate Based Rate or “ABR” loan). The LIBOR and ABR loans bear their respective interest rates plus the applicable margin indicated in the following table:


	Applicable Margin			Applicable Margin
Ratio of Total Outstanding Borrowings to Borrowing Base	for LIBOR Loans			for ABR Loans
Less than .50 to 1		2.00	%		0.50	%
Greater than or equal to .50 to 1 but less than .75 to 1		2.25	%		0.75	%
Greater than or equal to .75 to 1 but less than .85 to 1		2.50	%		1.00	%
Greater than .85 to 1 but less than or equal 1		2.75	%		1.25	%

An ABR loan does not have a set maturity date and may be repaid at any time upon the Company providing advance notification to the lenders under the Amended Credit Facility (the “Lenders”). Interest is paid quarterly on ABR loans based on the number of days an ABR loan is outstanding as of the last business day in March, June, September and December. The Company has the option to convert an ABR loan to a LIBOR-based loan upon providing advance notification to the Lenders. The minimum available loan term is one month and the maximum loan term is six months for LIBOR-based loans. Interest for LIBOR loans is paid upon maturity of the loan term. Interim interest is paid every three months for LIBOR loans that have loan terms that are greater than three months in duration. At the end of a LIBOR loan term, the Amended Credit Facility allows the Company to elect to continue a LIBOR loan with the same or a differing loan term or convert the borrowing to an ABR loan.

On a quarterly basis, the Company also pays a 0.50% annualized commitment fee on the average amount of borrowing base capacity not utilized during the quarter and fees calculated on the average amount of letter of credit balances outstanding during the quarter.

The Amended Credit Facility contains covenants that include, among others:

•

a prohibition against incurring debt, subject to permitted exceptions;

•

a prohibition against making dividends, distributions and redemptions, subject to permitted exceptions;

•

a prohibition against making investments, loans and advances, subject to permitted exceptions;

•

restrictions on creating liens and leases on the assets of the Company and its subsidiaries, subject to permitted exceptions;

•

restrictions on merging and selling assets outside the ordinary course of business;

•

restrictions on use of proceeds, investments, transactions with affiliates or change of principal business;

•

a provision limiting oil and natural gas derivative financial instruments;

	•		a requirement that the Company not allow a ratio of Total Net Debt (as defined in the Amended Credit Facility) to consolidated EBITDAX (as defined in the Amended Credit Facility) to be greater than 4.0 to 1.0 for the four quarters ended on the last day of each quarter; and

	•		a requirement that the Company maintain a Current Ratio (as defined in the Amended Credit Facility) of consolidated current assets (with exclusions as described in the Amended Credit Facility) to consolidated current liabilities (with exclusions as described in the Amended Credit Facility) of not less than 1.0 to 1.0 as of the last day of any fiscal quarter.

The Amended Credit Facility contains customary events of default. If an event of default occurs and is continuing, the Lenders may declare all amounts outstanding under the Amended Credit Facility to be immediately due and payable.

As of June 30, 2011, the Company had no borrowings and no outstanding letters of credit issued under the Amended Credit Facility, resulting in an unused borrowing base capacity of $137.5 million.

Senior Unsecured Notes — On February 2, 2011, the Company issued $400.0 million of 7.25% senior unsecured notes (the “Notes”) due February 1, 2019. Interest is payable on the Notes semi-annually in arrears on each February 1 and August 1, commencing August 1, 2011. The Notes are guaranteed on a senior unsecured basis by the Company’s material subsidiaries (“Guarantors”). These guarantees are full and unconditional and joint and several among the Guarantors. The issuance of these Notes resulted in net proceeds to the Company of approximately $390.0 million.

The Notes were issued under an Indenture, dated as of February 2, 2011 (the “Base Indenture”), among the Company and U.S. Bank National Association, as trustee (the “Trustee”), as amended and supplemented by the first supplemental indenture among the Company, the Guarantors and the Trustee, dated as of February 2, 2011 (the “Supplemental Indenture”; the Base Indenture, as amended and supplemented by the Supplemental Indenture, the “Indenture”).

At any time prior to February 1, 2014, the Company has the option to redeem up to 35% of the Notes at a redemption price of 107.25% of the principal amount, plus accrued and unpaid interest to the redemption date, with the proceeds of certain equity offerings so long as the redemption occurs within 180 days of completing such equity offering and at least 65% of the aggregate principal amount of the Notes remains outstanding after such redemption. Prior to February 1, 2015, the Company has the option to redeem some or all of the Notes for cash at a redemption price equal to 100% of their principal amount plus an applicable make-whole premium and accrued and unpaid interest to the redemption date. On and after February 1, 2015, the Company has the option to redeem some or all of the Notes at redemption prices (expressed as percentages of principal amount) equal to 103.625% for the twelve-month period beginning on February 1, 2015, 101.813% for the twelve-month period beginning February 1, 2016 and 100.00% beginning on February 1, 2017, plus accrued and unpaid interest to the redemption date. The Company estimates that the fair value of this option is immaterial at June 30, 2011.

In connection with the issuance of the Notes, the Company and Guarantors entered into a registration rights agreement that requires the Company and Guarantors to file a registration statement with the SEC so the holders of the Notes can exchange the Notes for registered notes that have substantially identical terms as the Notes. The Company and the Guarantors will use commercially reasonable efforts to cause the exchange to be completed within 360 days after the issuance of the Notes. Under certain circumstances, in lieu of a registered exchange offer, the Company must use commercially reasonable efforts to file a shelf registration statement for the resale of the Notes. If the Company fails to satisfy these obligations on a timely basis, the annual interest borne by the Notes will be increased by up to 1.0% per annum until the exchange offer is completed or the shelf registration statement is declared effective.

The Indenture restricts the Company’s ability and the ability of certain of its subsidiaries to: (i) incur additional debt or enter into sale and leaseback transactions; (ii) pay distributions on, redeem or repurchase, equity interests; (iii) make certain investments; (iv) incur liens; (v) enter into transactions with affiliates; (vi) merge or consolidate with another company; and (vii) transfer and sell assets. These covenants are subject to a number of important exceptions and qualifications. If at any time when the Notes are rated investment grade by both Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services and no Default (as defined in the Indenture) has occurred and is continuing, many of such covenants will terminate and the Company and its subsidiaries will cease to be subject to such covenants.

The Indenture contains customary events of default, including:

•		default in any payment of interest on any Note when due, continued for 30 days;

•		default in the payment of principal of or premium, if any, on any Note when due;

•		failure by the Company to comply with its other obligations under the Indenture, in certain cases subject to notice and grace periods;

•		payment defaults and accelerations with respect to other indebtedness of the Company and its Restricted Subsidiaries (as defined in the Indenture) in the aggregate principal amount of $10.0 million or more;

•		certain events of bankruptcy, insolvency or reorganization of the Company or a Significant Subsidiary (as defined in the Indenture) or group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary;

•		failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary to pay certain final judgments aggregating in excess of $10.0 million within 60 days; and

•		any guarantee of the Notes by a Guarantor ceases to be in full force and effect, is declared null and void in a judicial proceeding or is denied or disaffirmed by its maker.

Deferred Financing Costs — As of June 30, 2011, the Company had $1.6 million and $9.2 million of deferred financing costs related to the Amended Credit Facility and the Notes, respectively. The deferred financing costs are included in Deferred costs and other assets on the Company’s Condensed Consolidated Balance Sheet at June 30, 2011 and are being amortized over the respective terms of the Amended Credit Facility and the Notes. The amortization of these deferred financing costs is included in Interest expense on the Condensed Consolidated Statement of Operations.

8. Asset Retirement Obligations

The following table reflects the changes in the Company’s ARO during the six months ended June 30, 2011:


	ARO
	(In thousands)
Balance at December 31, 2010	$	7,640
Liabilities incurred during period		992
Liabilities settled during period		(9	)
Accretion expense		262
Revisions of previous estimates		1,112

Balance at June 30, 2011	$	9,997

9. Income Taxes

Prior to its corporate reorganization in connection with the IPO (see Note 1), the Company was a limited liability company and not subject to federal or state income tax (in most states). Accordingly, no provision for federal or state income taxes was recorded prior to the corporate reorganization as the Company’s equity holders were responsible for income tax on the Company’s profits. In connection with the closing of the Company’s IPO in June 2010, the Company merged into a corporation and became subject to federal and state income taxes.

The Company’s effective tax rate for the three and six month periods ended June 30, 2011 was 37.8%, which was consistent with the statutory tax rate applicable to the U.S. and the blended state rate for the states in which the Company conducts business. As of June 30, 2011, the Company did not have any uncertain tax positions requiring adjustments to its tax liability.

The Company had deferred tax assets for its federal and state tax loss carryforwards at June 30, 2011 recorded in noncurrent deferred taxes. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of June 30, 2011, management determined that a valuation allowance was not required for the tax loss carryforwards as they are expected to be fully utilized before expiration.

10. Income (Loss) Per Share

Basic earnings (loss) per share is computed by dividing income available to common stockholders by the weighted average number of shares outstanding for the periods presented. The calculation of diluted earnings (loss) per share includes the impact of potentially dilutive non-vested restricted shares outstanding during the periods presented, unless their effect is anti-dilutive. There are no adjustments made to income available to common stockholders in the calculation of diluted earnings (loss) per share.

The following is a calculation of the basic and diluted weighted-average shares outstanding for the three and six months ended June 30, 2011 and 2010:


	Three Months				Six Months
	Ended June 30,				Ended June 30,
	2011		2010		2011		2010
			(In thousands)
Basic weighted average common shares outstanding		92,048		8,088		92,047		4,066
Dilution effect of stock awards at end of period(1)		103		—		130		—

Diluted weighted average common shares outstanding		92,151		8,088		92,177		4,066


Anti-dilutive stock-based compensation awards		272		215		173		215


(1)		Because the Company reported a net loss for the three and six months ended June 30, 2010, no unvested stock awards were included in computing diluted loss per share because the effect would have been anti-dilutive.

11. Commitments and Contingencies

Lease Obligations — On January 12, 2011, the Company executed an amendment to its office space lease agreement for an additional 11,638 square feet of space within its current office building. Under the terms of the amendment, the Company’s rental obligation for the new premises commenced on May 1, 2011 and terminates on September 30, 2017. The Company’s total rental commitments under non-cancelable leases for office space and other property and equipment at June 30, 2011 were $8.0 million.

Drilling Contracts — As of June 30, 2011, the Company had certain drilling rig contracts with initial terms greater than one year. In the event of early contract termination under these contracts, the Company would be obligated to pay approximately $41.4 million as of June 30, 2011 for the days remaining through the end of the primary terms of the contracts.

Volume Commitment Agreements — As of June 30, 2011, the Company had certain agreements with an aggregate requirement to deliver a minimum quantity of approximately 10.5 MMBbl and 8.8 Bcf from its Williston Basin project areas within a specified timeframe. Future obligations under these agreements are approximately $35.6 million as of June 30, 2011.

Fracturing Services — As of June 30, 2011, the Company had certain agreements with third party service companies for an initial term greater than one year. In the event of early contract termination under these agreements, the Company would be obligated to pay approximately $51.5 million as of June 30, 2011 for the months remaining through the end of the primary term of the agreement.

Litigation — The Company is party to various legal and/or regulatory proceedings from time to time arising in the ordinary course of business. The Company believes all such matters are without merit and involve amounts which, if resolved unfavorably, either individually or in the aggregate, will not have a material adverse effect on its financial condition, results of operations or cash flows.

12. Condensed Consolidating Financial Information

On February 2, 2011, the Company issued $400.0 million of Notes (see Note 7). The Notes are guaranteed on a senior unsecured basis by the Guarantors, which are 100% owned by the Company. These guarantees are full and unconditional and joint and several among the Guarantors. The Notes were offered and sold to qualified institutional buyers in reliance on Rule 144A and non-U.S. persons under Regulation S. They have not been registered under the Securities Act of 1933, as amended, or any state securities laws. Certain of the Company’s immaterial wholly owned subsidiaries do not guarantee the Notes (“Non-Guarantor Subsidiaries”).

The following financial information reflects condensed consolidating financial information of the Company (“Issuer”) and its Guarantors on a combined basis, prepared on the equity basis of accounting. The Non-Guarantor Subsidiaries are minor and, therefore, not presented separately. The information is presented in accordance with the requirements of Rule 3-10 under the SEC’s Regulation S-X. The financial information may not necessarily be indicative of results of operations, cash flows or financial position had the Guarantors operated as independent entities. The Company has not presented separate financial and narrative information for each of the Guarantors because it believes such financial and narrative information would not provide any additional information that would be material in evaluating the sufficiency of the Guarantors.

13. Subsequent Events

The Company has evaluated the period after the balance sheet date, noting no subsequent events or transactions that required recognition or disclosure in the financial statements, other than as noted below.

Derivative Instruments — In July 2011, the Company entered into new two-way and three-way costless collar options and deferred premium put contracts, all of which settle monthly based on the West Texas Intermediate crude oil index price, for a total notional amount of 1,675,000 barrels in 2012, 823,000 barrels in 2013 and 62,000 barrels in 2014. The deferred premium put contracts had a total liability of $9.7 million on the date of execution. These derivative instruments do not qualify for and were not designated as hedging instruments for accounting purposes.

Item 2. — Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in our Annual Report on Form 10-K for the year ended December 31, 2010 (“2010 Annual Report”), as well as the unaudited condensed consolidated financial statements and notes thereto included in this Quarterly Report on Form 10-Q .

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities and Exchange Act of 1934, as amended. These forward-looking statements are subject to a number of risks and uncertainties, many of which are beyond our control. All statements, other than statements of historical fact included in this Quarterly Report on Form 10-Q, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this Quarterly Report on Form 10-Q, the words “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “may,” “continue,” “predict,” “potential,” “project” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. In particular, the factors discussed below and detailed under Item 1A. “Risk Factors” in our 2010 Annual Report, could affect our actual results and cause our actual results to differ materially from expectations, estimates, or assumptions expressed in, forecasted in, or implied in such forward-looking statements.

Forward-looking statements may include statements about:

•

business strategy;

•

reserves;

•

technology;

•

cash flows and liquidity;

•

financial strategy, budget, projections and operating results;

•

oil and natural gas realized prices;

•

timing and amount of future production of oil and natural gas;

•

availability of drilling, completion and production equipment and materials;

•

availability of qualified personnel;

•

owning and operating a services company;

•

the amount, nature and timing of capital expenditures, including future development costs;

•

availability and terms of capital;

•

drilling and completion of wells;

•

infrastructure for salt water disposal;

•

gathering, transportation and marketing of oil and natural gas;

•

exploitation or property acquisitions;

•

costs of exploiting and developing our properties and conducting other operations;

•

general economic conditions;

•

inclement weather conditions;

•

competition in the oil and natural gas industry;

•

effectiveness of our risk management activities;

	•		environmental liabilities;

	•		counterparty credit risk;

•

governmental regulation and taxation of the oil and natural gas industry;

•

developments in oil-producing and natural gas-producing countries;

•

uncertainty regarding our future operating results;

•

estimated future net reserves and present value thereof; and

•

plans, objectives, expectations and intentions contained in this report that are not historical.

All forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q. We disclaim any obligation to update or revise these statements unless required by Securities law, and you should not place undue reliance on these forward-looking statements. Although we believe that our plans, intentions and expectations reflected in or suggested by the forward-looking statements we make in this Quarterly Report on Form 10-Q are reasonable, we can give no assurance that these plans, intentions or expectations will be achieved. Some of the key factors which could cause actual results to vary from our expectations include changes in oil and natural gas prices, the timing of planned capital expenditures, availability of acquisitions, uncertainties in estimating proved reserves and forecasting production results, operational factors affecting the commencement or maintenance of producing wells, the condition of the capital markets generally, as well as our ability to access them, the proximity to and capacity of transportation facilities, and uncertainties regarding environmental regulations or litigation and other legal or regulatory developments affecting our business, as well as those factors discussed below and elsewhere in this Quarterly Report on Form 10-Q, all of which are difficult to predict. In light of these risks, uncertainties and assumptions, the forward-looking events discussed may not occur. These cautionary statements qualify all forward-looking statements attributable to us or persons acting on our behalf.

Overview

We are an independent exploration and production company focused on the development and acquisition of unconventional oil and natural gas resources primarily in the Williston Basin. Since our inception, we have emphasized the acquisition of properties that provide current production and significant upside potential through further development. Our drilling activity is primarily directed toward projects that we believe can provide us with repeatable successes in the Bakken formation.

Our use of capital for acquisitions and development allows us to direct our capital resources to what we believe to be the most attractive opportunities as market conditions evolve. We have historically acquired properties that we believe will meet or exceed our rate of return criteria. For acquisitions of properties with additional development, exploitation and exploration potential, we have focused on acquiring properties that we expect to operate so that we can control the timing and implementation of capital spending. In some instances, we have acquired non-operated property interests at what we believe to be attractive rates of return either because they provided a foothold in a new area of interest or complemented our existing operations. We intend to continue to acquire both operated and non-operated properties to the extent we believe they meet our return objectives. In addition, our willingness to acquire non-operated properties in new areas provides us with geophysical and geologic data that may lead to further acquisitions in the same area, whether on an operated or non-operated basis.

Due to the geographic concentration of our oil and natural gas properties in the Williston Basin, we believe the primary sources of opportunities, challenges and risks related to our business for both the short and long-term are:

•

Commodity prices for oil and natural gas;

•

Commodity price differentials (price differences between market indices and actual realizations);

•

Transportation capacity; and

•

Availability and cost of services (primarily drilling and completion services).

Our revenue, profitability and future growth rate depend substantially on factors beyond our control, such as economic, political and regulatory developments as well as competition from other sources of energy. Oil and natural gas prices historically have been volatile and may fluctuate widely in the future. Sustained periods of low prices for oil or natural gas could materially and adversely affect our financial position, our results of operations, the quantities of oil and natural gas reserves that we can economically produce and our access to capital.

Prices for oil and natural gas can fluctuate significantly in response to relatively minor changes in the global and regional supply of and demand for oil and natural gas. We enter into crude oil sales contracts with purchasers who have access to crude oil transportation capacity, utilize derivative financial instruments to manage our commodity price risk, and enter into physical delivery contracts to manage our price differentials.

Our ability to develop and hold our existing undeveloped leasehold acreage is primarily dependent upon having access to drilling rigs and completion services. The utilization of existing drilling rigs and of existing completion service equipment in the Williston Basin is at an all-time high. This has resulted in drilling rigs, completion equipment and crews being imported from Canada and other parts of the United States. To ensure access to drilling rigs, we have entered into fixed-term drilling rig contracts for periods of up to three years and currently have nine drilling rigs under contract. We also enter into service contracts to ensure the availability of completion services and the timely fracture stimulation of newly drilled wells. Our large concentrated acreage position potentially provides us with a multi-year inventory of drilling projects and requires some forward planning visibility for obtaining services.

Three months ended June 30, 2011 as compared to three months ended June 30, 2010

Oil and natural gas revenues . Our oil and natural gas sales revenues increased $40.5 million, or 151%, to $67.2 million during the three months ended June 30, 2011 as compared to the three months ended June 30, 2010. Our revenues are a function of oil and natural gas production volumes sold and average sales prices received for those volumes. Average daily production sold increased by 3,432 Boe per day, or 77%, to 7,893 Boe per day during the three months ended June 30, 2011 as compared to the three months ended June 30, 2010. The increase in average daily production sold was primarily a result of our well completions during the last two quarters of 2010 and the first two quarters of 2011. Well completions in our West Williston, East Nesson and Sanish project areas increased average daily production by approximately 3,212 Boe per day, 1,190 Boe per day and 649 Boe per day, respectively, during the second quarter of 2011 as compared to the second quarter of 2010. The higher production amounts sold increased revenues by $29.5 million, and the remaining $11.0 million increase in revenues was attributable to higher oil and gas sales prices during the three months ended June 30, 2011. Average oil sales prices, without realized derivatives, increased by $28.29/Bbl, or 42%, to an average of $95.48/Bbl for the three months ended June 30, 2011 as compared to the three months ended June 30, 2010.

Six months ended June 30, 2011 as compared to six months ended June 30, 2010

Oil and natural gas revenues . Our oil and natural gas sales revenues increased $79.1 million, or 169%, to $126.0 million during the six months ended June 30, 2011 as compared to the six months ended June 30, 2010. Our revenues are a function of oil and natural gas production volumes sold and average sales prices received for those volumes. Average daily production sold increased by 4,110 Boe per day, or 106%, to 7,991 Boe per day during the six months ended June 30, 2011 as compared to the six months ended June 30, 2010. The increase in average daily production sold was primarily a result of our well completions during the last two quarters of 2010 and the first two quarters of 2011. These well completions in our West Williston, East Nesson and Sanish project areas increased average daily production by approximately 3,070 Boe per day, 1,176 Boe per day and 643 Boe per day, respectively, during the first six months of 2011. The higher production amounts sold increased revenues by $65.5 million, and the remaining $13.6 million increase in revenues was attributable to higher oil and gas sales prices during the six months ended June 30, 2011. Average oil sales prices, without realized derivatives, increased by $20.42/Bbl, or 30%, to an average of $88.86/Bbl for the six months ended June 30, 2011 as compared to the six months ended June 30, 2010.

Three months ended June 30, 2011 compared to three months ended June 30, 2010

Lease operating expenses . Lease operating expenses increased $3.3 million to $6.2 million for the three months ended June 30, 2011 compared to the three months ended June 30, 2010. This increase was due to an increased number of producing wells and increased water production period over period. The unit operating costs increased from $7.21 per Boe for the three months ended June 30, 2010 to $8.63 per Boe for the three months ended June 30, 2011, primarily as a result of increased costs associated with operating in inclement weather during the second quarter of 2011.

Production taxes . Our production taxes for the three months ended June 30, 2011 and 2010 were 10.5% and 10.1%, respectively, as a percentage of oil and natural gas sales. The 2011 production tax rate was higher than the 2010 production tax rate due to an increased portion of our oil revenues subject to taxation in North Dakota, which imposes an 11.5% production tax rate.

Depreciation, depletion and amortization (DD&A) . DD&A expense increased $4.3 million to $13.1 million for the three months ended June 30, 2011 compared to the three months ended June 30, 2010. The increase in DD&A expense for the three months ended June 30, 2011 was primarily due to the 77% production increase. The DD&A rate for the three months ended June 30, 2011 was $18.24 per Boe compared to $21.63 per Boe for the three months ended June 30, 2010. The lower DD&A rate was due to the lower cost of reserve additions associated with our 2010 acquisitions and drilling activities.

Impairment of oil and gas properties . During the three months ended June 30, 2011 and 2010, we recorded non-cash impairment charges of $1.5 million and $7.9 million, respectively, for unproved property leases that expired during the period. No impairment charges of proved oil and gas properties were recorded for the three months ended June 30, 2011 or 2010.

General and administrative expenses . Our general and administrative expenses increased $2.9 million for the three months ended June 30, 2011 from $3.7 million for the three months ended June 30, 2010. Of this increase, approximately $2.2 million was due to the impact of our organizational growth on employee compensation and $1.0 million was due to the amortization of our restricted stock awards for the three months ended June 30, 2011. As of June 30, 2011, we had 88 full-time employees compared to 45 full-time employees as of June 30, 2010.

Derivative instruments . As a result of our derivative activities, we incurred cash settlement losses of $4.1 million and $33 thousand for the three months ended June 30, 2011 and 2010, respectively. In addition, as a result of forward oil price decreases, we recognized $31.7 million and $3.4 million of non-cash unrealized mark-to-market derivative gains during the three months ended June 30, 2011 and 2010, respectively.

Interest expense . Interest expense increased $6.3 million to $6.8 million for the three months ended June 30, 2011 compared to the three months ended June 30, 2010. The increase was the result of interest related to our senior unsecured notes issued in February 2011 at an interest rate of 7.25%. There were no borrowings under our revolving credit facility during the three months ended June 30, 2011 compared to a weighted average outstanding debt balance of $48.2 million at a weighted average interest rate of 3.21% for the three months ended June 30, 2010.

Income taxes. Prior to our corporate reorganization, we were a limited liability company not subject to entity-level income tax. In connection with the closing of our IPO in June 2010, we merged into a corporation and became subject to federal and state entity-level taxation. In connection with our corporate reorganization, an initial net deferred tax liability of $29.9 million was established for differences between the tax and book basis of our assets and liabilities and a corresponding tax expense was recorded in our Consolidated Statement of Operations for the three months ended June 30, 2010. Our income tax expense was $20.2 million for the three months ended June 30, 2011, resulting in an effective tax rate of 37.8%. Our effective tax rate is expected to continue to closely approximate the statutory rate applicable to the U.S. and the blended state rate of the states in which we conduct business.

Six months ended June 30, 2011 compared to six months ended June 30, 2010

Lease operating expenses . Lease operating expenses increased $6.2 million to $12.1 million for the six months ended June 30, 2011 compared to the six months ended June 30, 2010. This increase was primarily due to an increased number of producing wells from our West Williston acquisitions that were completed in the fourth quarter of 2010, and as a result of our well completions during 2010 and the first two quarters of 2011. The unit operating costs remained consistent for the six months ended June 30, 2011 and 2010 at $8.39 and $8.40 per Boe, respectively.

Production taxes . Our production taxes for the six months ended June 30, 2011 and 2010 were 10.5% and 9.9%, respectively, as a percentage of oil and natural gas sales. The production tax rate for the six months ended June 30, 2011 was higher than the production tax rate for the six months ended June 30, 2010 due to an increased portion of our oil revenues subject to taxation in North Dakota, which imposes an 11.5% production tax rate.

DD&A . DD&A expense increased $12.3 million to $26.9 million for the six months ended June 30, 2011 compared to the six months ended June 30, 2010. The increase in DD&A expense for the six months ended June 30, 2011 was primarily due to the production increases from the West Williston acquisitions completed in the fourth quarter of 2010, and as a result of our well completions during 2010 and the first two quarters of 2011. The DD&A rate for the six months ended June 30, 2011 was $18.61 per Boe compared to $20.83 per Boe for the six months ended June 30, 2010. This decrease in the DD&A rate was due to the lower cost of reserve additions associated with our 2010 acquisition and drilling activities over the second half of 2010 and the first two quarters of 2011.

Impairment of oil and gas properties . During the six months ended June 30, 2011 and 2010, we recorded non-cash impairment charges of $2.9 million and $11.0 million, respectively, for unproved property leases that expired during these periods. No impairment charges of proved oil and gas properties were recorded for the six months ended June 30, 2011 or 2010.

Stock-based compensation expense . For the six months ended June 30, 2010, we recorded a $5.2 million non-cash charge for stock-based compensation expense associated with OPM’s grant of 1.0 million Class C Unit Interests (“C Units”). The C Units were granted on March 24, 2010 to individuals who were employed by us as of February 1, 2010 and who were not executive officers or key employees with an existing capital investment in OPM. The C Units were membership interests in OPM and not direct interests in us. The C Units were non-transferable, had no voting power and vested immediately on the grant date. Based on the characteristics of these awards, we concluded that they represented equity-type awards and we accounted for the value of these awards as if they had been awarded by us. We used fair-value-based methods to determine the value of stock-based compensation awarded to our employees and recognized the entire amount as expense due to the immediate vesting of the awards, with no future requisite service period required by the employees. As of December 31, 2010, OPM had distributed substantially all cash or requisite common stock to its members based on membership interests and distribution percentages. No stock-based compensation expense was recorded for the six months ended June 30, 2011 related to the C Units.

General and administrative . Our general and administrative expenses increased $5.3 million for the six months ended June 30, 2011 from $7.3 million for the six months ended June 30, 2010. Of this increase, approximately $3.5 million was due to the impact of our organizational growth on employee compensation and $1.6 million was due to the amortization of our restricted stock awards for the six months ended June 30, 2011. As of June 30, 2011, we had 88 full-time employees compared to 45 full-time employees as of June 30, 2010.

Derivative instruments . As a result of our derivative activities, we incurred cash settlement losses of $4.7 million and $59 thousand for the six months ended June 30, 2011 and 2010, respectively. In addition, as a result of forward oil price decreases, we recognized a $0.5 million and a $3.0 million unrealized mark-to-market non-cash derivative gain during the six months ended June 30, 2011 and 2010, respectively.

Interest expense . Interest expense increased by $11.1 million to $12.0 million for the six months ended June 30, 2011 compared to the six months ended June 30, 2010. The increase was the result of interest related to our senior unsecured notes issued in February 2011 at an interest rate of 7.25%. There were no borrowings under our revolving credit facility during the six months ended June 30, 2011 compared to a weighted average outstanding debt balance of $30.8 million at a weighted average interest rate of 3.11% for the six months ended June 30, 2010.

Income taxes . Prior to our corporate reorganization, we were a limited liability company not subject to entity level income tax. In connection with the closing of our IPO in June 2010, we merged into a corporation and became subject to federal and state entity-level taxation. In connection with our corporate reorganization, an initial net deferred tax liability of $29.9 million was established for differences between the tax and book basis of our assets and liabilities and a corresponding tax expense was recorded in our Consolidated Statement of Operations for the six months ended June 30, 2010. Our income tax expense was $16.1 million for the six months ended June 30, 2011, resulting in an effective tax rate of 37.8%. Our effective tax rate is expected to continue to closely approximate the statutory rate applicable to the U.S. and the blended state rate of the states in which we conduct business.

Liquidity and Capital Resources

Our primary sources of liquidity as of the date of this report have been proceeds from our IPO in June 2010, proceeds from our private placement of senior unsecured notes in February 2011, borrowings under our revolving credit facility, cash flows from operations and capital contributions from private investors prior to our IPO. Our primary use of capital has been for the acquisition, development and exploration of oil and natural gas properties. We continually monitor potential capital sources, including equity and debt financings, in order to meet our planned capital expenditures and liquidity requirements. Our future success in growing proved reserves and production will be highly dependent on our ability to access outside sources of capital.

Our cash flows for the six months ended June 30, 2011 and 2010 are presented below:


	Six Months Ended
	June 30,
	2011			2010
	(In thousands)
Net cash provided by operating activities	$	102,095		$	20,630
Net cash used in investing activities		(335,024	)		(98,217	)
Net cash provided by financing activities		389,414			363,256

Net increase in cash and cash equivalents	$	156,485		$	285,669

Our Condensed Consolidated Statement of Cash Flows for the three months ended March 31, 2011 contained an understatement of net cash provided by operating activities and net cash used in investing activities of $3.4 million. This misstatement was a result of management reclassifying changes associated with capital expenditure accrual amounts, included in working capital accounts, from operating cash flows to capital expenditures in investing cash flows. We have concluded that the misstatement was not material to the three months ended March 31, 2011, and as such, corrected the misstatement during preparation of this Quarterly Report on Form 10-Q. There was no impact on our condensed consolidated balance sheet or condensed consolidated statement of operations for the three months ended March 31, 2011.

Cash flows provided by operating activities

Our cash flows depend on many factors, including the price of oil and natural gas and the success of our development and exploration activities as well as future acquisitions. We actively manage our exposure to commodity price fluctuations by executing derivative transactions to mitigate the change in oil prices on a portion of our production, thereby mitigating our exposure to oil price declines, but these transactions may also limit our cash flow in periods of rising oil prices.

Net cash provided by operating activities was $102.1 million and $20.6 million for the six months ended June 30, 2011 and 2010, respectively. The increase in cash flows provided by operating activities for the period ended June 30, 2011 as compared to 2010 was primarily the result of an increase in oil and natural gas production of 106%. In addition, at June 30, 2011, we had a working capital surplus of $381.2 million. This surplus was primarily attributable to our cash and short-term investment balances as a result of the net proceeds from the issuance of our senior unsecured notes in February 2011.

Cash flows used in investing activities

Net cash used in investing activities was $335.0 million and $98.2 million during the six months ended June 30, 2011 and 2010, respectively. The increase in cash used in investing activities for the six months ended June 30, 2011 compared to 2010 of $236.8 million was attributable to increased levels of capital expenditures for drilling, development and acquisition costs and purchases of short-term investments.

Our capital expenditures for drilling, development and acquisition costs are summarized in the following table:


	Six Months Ended
	June 30, 2011
	(In thousands)
Project Area:
West Williston	$	162,327
East Nesson		27,721
Sanish		10,322
Other(1)		161

Total(2)	$	200,531


(1)		Represents data relating to our properties in the Barnett shale.

(2)		Capital expenditures reflected in the table above differ from the amounts shown in the statement of cash flows in our condensed consolidated financial statements because amounts reflected in the table above include changes in accrued liabilities from the previous reporting period for capital expenditures, while the amounts presented in the statement of cash flows are presented on a cash basis. The capital expenditures amount presented in the statement of cash flows also includes cash paid for other property and equipment as well as cash paid for asset retirement obligations.

Our total 2011 capital expenditure budget was $490 million at June 30, 2011. On August 1, 2011, our Board of Directors increased our total 2011 capital expenditure budget to $627 million. Our exploration and production budget increased by $97 million to $587 million, and consists of:

•

$527 million for drilling and completing operated and non-operated wells;

•

$60 million for maintaining and expanding our leasehold position, constructing infrastructure to support production in our core project areas, micro-seismic work, purchasing seismic data and other test work.

Additionally, the 2011 budget includes expenditures related to our newly formed subsidiary, OWS, totaling $24 million for equipment and materials related to start-up costs necessary to provide select well services to OPNA. The 2011 budget also includes $16 million of other non-exploration and production capital expenditures for an operations building in Williston, North Dakota, and other equipment.

While we have budgeted $627 million for these purposes, the ultimate amount of capital we will expend may fluctuate materially based on market conditions and the success of our drilling and operations results as the year progresses. We believe that the net proceeds from our private offering of senior unsecured notes of approximately $390.0 million, which closed on February 2, 2011, together with cash on hand and cash flows from operating activities should be sufficient to fund our 2011 capital expenditure budget. However, because the operated wells funded by our 2011 drilling plan represent only a small percentage of our gross identified drilling locations, we may be required to generate or raise multiples of this amount of capital to develop our entire inventory of identified drilling locations should we elect to do so.

Our capital budget may be adjusted as business conditions warrant. The amount, timing and allocation of capital expenditures is largely discretionary and within our control. If oil and natural gas prices decline or costs increase significantly, we could defer a significant portion of our budgeted capital expenditures until later periods to prioritize capital projects that we believe have the highest expected returns and potential to generate near-term cash flows. We routinely monitor and adjust our capital expenditures in response to changes in prices, availability of financing, drilling and acquisition costs, industry conditions, the timing of regulatory approvals, the availability of rigs, success or lack of success in drilling activities, contractual obligations, internally generated cash flows and other factors both within and outside our control.

Cash flows provided by financing activities

Net cash provided by financing activities was $389.4 million and $363.3 million for the six months ended June 30, 2011 and 2010, respectively. For the six months ended June 30, 2011, cash sourced through financing activities was primarily provided by the net proceeds from the issuance of our senior unsecured notes in February 2011. For the six months ended June 30, 2010, cash sourced through financing activities was primarily provided by net proceeds from the sale of common stock in our IPO.

Senior Secured Revolving Line of Credit . On June 16, 2011, we entered into our fourth amendment to our amended and restated credit facility (“Amended Credit Facility”). The Amended Credit Facility provides for a senior secured revolving line of credit of up to $600.0 million and matures in February 2015. Borrowings under the Amended Credit Facility are collateralized by perfected first priority liens and security interests on substantially all of our assets, including mortgage liens on oil and natural gas properties having at least 80% of the reserve value as determined by reserve reports. At our election, interest is generally determined by reference to (i) the London interbank offered rate, or LIBOR, plus an applicable margin between 2.00% and 2.75% per annum; or (ii) a domestic bank prime rate plus an applicable margin between 0.50% and 1.25% per annum.

The Amended Credit Facility provides for semi-annual redeterminations on April 1 and October 1 of each year. A redetermination of our borrowing base was completed at our request on January 21, 2011 in lieu of the scheduled April 1, 2011 semi-annual redetermination. As a result of this redetermination, our borrowing base increased from $120 million to $150 million, and was then automatically reduced to $137.5 million in connection with the issuance of our senior unsecured notes on February 2, 2011 (described below). As of June 30, 2011, we had no borrowings and no outstanding letters of credit under the Amended Credit Facility.

The Amended Credit Facility also contains certain financial covenants and customary events of default. If an event of default occurs and is continuing, the lenders under our Amended Credit Facility may declare all amounts outstanding under the Amended Credit Facility to be immediately due and payable. As of June 30, 2011, we were in compliance with the financial covenants of the Amended Credit Facility.

Senior Unsecured Notes. On February 2, 2011, we issued $400.0 million of 7.25% senior unsecured notes due February 1, 2019 (the “Notes”). Interest is payable on the notes semi-annually in arrears on each February 1 and August 1, commencing August 1, 2011. These notes are guaranteed on a senior unsecured basis by our material subsidiaries. The issuance of these notes resulted in net proceeds to us of approximately $390.0 million, which we are using to fund our exploration, development and acquisition program and for general corporate purposes.

The Notes were issued under an Indenture (the “Base Indenture”), among the Company and U.S. Bank National Association, as trustee (the “Trustee”), as amended and supplemented by the first supplemental indenture among the Company, the Guarantors and the Trustee, dated as of February 2, 2011 (the “Supplemental Indenture”; the Base Indenture, as amended and supplemented by the Supplemental Indenture, the “Indenture”).

(3)		Amounts represent our estimate of future asset retirement obligations on an undiscounted basis. Because these costs typically extend many years into the future, estimating these future costs requires management to make estimates and judgments that are subject to future revisions based upon numerous factors, including the rate of inflation, changing technology and the political and regulatory environment. See Note 8 to our unaudited condensed consolidated financial statements.

Critical Accounting Policies and Estimates

There have been no material changes in our critical accounting policies and estimates from those disclosed in our 2010 Annual Report other than those noted below.

Recent Accounting Pronouncements

Fair value . In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (“ASU 2011-04”). ASU 2011-04 changes some fair value measurement principles under U.S. GAAP, including a change in the valuation premise and the application of premiums and discounts. It also contains some new disclosure requirements under U.S. GAAP. It is effective for interim and annual periods beginning after December 15, 2011. We do not expect the adoption of this new guidance to have a significant impact on our financial position, cash flows or results of operations.

Comprehensive income . In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (“ASU 2011-05”), which provides an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. It does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. ASU 2011-05 is effective for interim and annual periods beginning after December 15, 2011 and will be applied retrospectively. We do not expect the adoption of this new guidance to have any impact on our financial position, cash flows or results of operations.

Off-Balance Sheet Arrangements

We do not currently have any off-balance sheet arrangements.

Item 3. — Quantitative and Qualitative Disclosures About Market Risk

The following market risk disclosures should be read in conjunction with the quantitative and qualitative disclosures about market risk contained in our 2010 Annual Report, as well as with the unaudited condensed consolidated financial statements and notes thereto included in this Quarterly Report on Form 10-Q.

We are exposed to a variety of market risks including commodity price risk, interest rate risk and counterparty and customer risk. We address these risks through a program of risk management, including the use of derivative instruments.

Commodity price exposure risk. We are exposed to market risk as the prices of oil and natural gas fluctuate as a result of changes in supply and demand and other factors. To partially reduce price risk caused by these market fluctuations, we have entered into derivative instruments in the past and expect to enter into derivative instruments in the future to cover a significant portion of our future production.

We utilize derivative financial instruments to manage risks related to changes in oil prices. As of June 30, 2011, we utilized two-way and three-way collar options to reduce the volatility of oil prices on a significant portion of our future expected oil production. A two-way collar is a combination of options: a sold call and a purchased put. The purchased put establishes a minimum price (floor) and the sold call establishes a maximum price (ceiling) we will receive for the volumes under contract. A three-way collar is a combination of options: a sold call, a purchased put and a sold put. The purchased put establishes a minimum price (floor), unless the market price falls below the sold put (sub-floor), at which point the minimum price would be NYMEX-WTI plus the difference between the purchased put and the sold put strike price. The sold call establishes a maximum price (ceiling) we will receive for the volumes under contract.

We recognize all derivative instruments at fair value. The credit standing of our counterparties is analyzed and factored into the fair value amounts recognized on the balance sheet. Derivative assets and liabilities arising from our derivative contracts with the same counterparty are also reported on a net basis, as all counterparty contracts provide for net settlement.

The following is a summary of our outstanding commodity derivative instruments as of June 30, 2011:


		Total
		Notional		Average
Settlement	Derivative	Amount of		Sub-Floor		Average		Average		Fair Value Asset
Period	Instrument	Oil (Barrels)		Price		Floor Price		Ceiling Price		(Liability)
										(In thousands)
2011	Two-Way Collars		1,472,505			$	85.10	$	106.07		(2,146	)
2011	Three-Way Collars		91,500	$	60.00	$	80.00	$	94.98		(391	)
2012	Two-Way Collars		1,756,718			$	85.49	$	106.44		(4,388	)
2012	Three-Way Collars		685,500	$	66.11	$	86.11	$	110.28		(1,722	)
2013	Two-Way Collars		473,500			$	88.69	$	106.99		(914	)
2013	Three-Way Collars		396,000	$	69.41	$	95.68	$	120.60		(330	)
2014	Two-Way Collars		31,000			$	90.00	$	107.20		(43	)
2014	Three-Way Collars		31,000	$	70.00	$	90.00	$	122.45		(19	)

										$	(9,953	)

Interest rate risk. We had $400.0 million of senior unsecured notes outstanding at June 30, 2011, which have a fixed cash interest rate of 7.25% per annum. During the first six months of 2011, we had no indebtedness outstanding under our revolving credit facility. We may utilize interest rate derivatives to alter interest rate exposure in an attempt to reduce interest rate expense related to existing debt issued under our revolving credit facility. Interest rate derivatives would be used solely to modify interest rate exposure and not to modify the overall leverage of the debt portfolio.

Counterparty and customer credit risk. Joint interest receivables arise from billing entities which own partial interest in the wells we operate. These entities participate in our wells primarily based on their ownership in leases on which we choose to drill. We have limited ability to control participation in our wells. We are also subject to credit risk due to concentration of our oil and natural gas receivables with several significant customers. The inability or failure of our significant customers to meet their obligations to us or their insolvency or liquidation may adversely affect our financial results. In addition, our oil and natural gas derivative arrangements expose us to credit risk in the event of nonperformance by counterparties. However, in order to mitigate the risk of nonperformance, we only enter into derivative contracts with counterparties that are high credit-quality financial institutions, all of which are lenders under our revolving credit facility. This risk is also managed by spreading our derivative exposure across several institutions and limiting the hedged volumes placed under individual contracts.

While we do not require all of our customers to post collateral and we do not have a formal process in place to evaluate and assess the credit standing of our significant customers for oil and natural gas receivables and the counterparties on our derivative instruments, we do evaluate the credit standing of such counterparties as we deem appropriate under the circumstances. This evaluation may include reviewing a counterparty’s credit rating, latest financial information and, in the case of a customer with which we have receivables, their historical payment record, the financial ability of the customer’s parent company to make payment if the customer cannot and undertaking the due diligence necessary to determine credit terms and credit limits. Several of our significant customers for oil and natural gas receivables have a credit rating below investment grade or do not have rated debt securities. In these circumstances, we have considered the lack of investment grade credit rating in addition to the other factors described above.

The counterparties on our derivative instruments currently in place are lenders under our revolving credit facility with investment grade ratings. We are likely to enter into any future derivative instruments with these or other lenders under our revolving credit facility, which also carry investment grade ratings. Furthermore, the agreements with each of the counterparties on our derivative instruments contain netting provisions. As a result of these netting provisions, our maximum amount of loss due to credit risk is limited to the net amounts due to and from the counterparties under the derivative contracts. The Company had a net derivative liability position of approximately $10.0 million at June 30, 2011.

Item 4. — Controls and Procedures

Material Weakness in Internal Control over Financial Reporting. Prior to the completion of our IPO, we were a private company with limited accounting personnel to adequately execute our accounting processes and other supervisory resources with which to address our internal control over financial reporting. As previously discussed in Item 9A. “Controls and Procedures” of our 2010 Annual Report, we did not maintain an effective control environment in that the design and execution of our controls did not consistently result in effective review and supervision by individuals with financial reporting oversight roles. The lack of adequate staffing levels resulted in insufficient time spent on review and approval of certain information used to prepare our financial statements, which resulted in certain control deficiencies. We concluded that these control deficiencies constituted a material weakness in our control environment.

Remediation Activities. Although remediation efforts are still in progress, management has taken steps to address the cause of the material weakness by putting into place new accounting processes and control procedures. In addition, we have hired additional accounting and financial reporting staff since our IPO, implemented additional analysis and reconciliation procedures and increased the levels of review and approval. Additionally, we have begun taking steps to comprehensively document and analyze our system of internal control over financial reporting in preparation for our first management report on internal control over financial reporting required in connection with our Annual Report on Form 10-K for the year ended December 31, 2011.

Management will continue to evaluate the design and effectiveness of these control changes in conjunction with its ongoing evaluation, review, formalization and testing of our internal control environment over the remainder of 2011. We will not complete our review until after this Quarterly Report on Form 10-Q is filed. We cannot predict the outcome of our review at this time. During the course of the review, we may identify additional control deficiencies, which could give rise to additional significant deficiencies and other material weaknesses.

Evaluation of Disclosure Controls and Procedures . As required by Rule 13a-15(b) of the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 30, 2011. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. In light of the previously identified material weakness described above, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of June 30, 2011. Notwithstanding the existence of the material weakness, management concluded that the financial statements and other financial information included in this Quarterly Report on Form 10-Q present fairly, in all material respects, the financial condition, results of operations and cash flows for all periods presented.

Changes in Internal Control over Financial Reporting . As our remediation efforts are still in progress, as described above, there were changes in our system of internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) that occurred during the three months ended June 30, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
