Accounting Policies [Abstract]	'
Organization and Nature of Operations and Summary of Significant Accounting Policies	'
	Note 1. Organization and Nature of Operations and Summary of Significant Accounting Policies
	Organization and Nature of Operations
	We are an independent oil and gas company incorporated in the state of Delaware and headquartered in Tulsa, Oklahoma. We also have corporate offices located in Denver, Colorado and Houston, Texas as well as several field locations throughout our core operating areas. We engage in the exploration, development and production of oil and gas properties located onshore in the United States. We have operations and acreage positions in the Anadarko, Arkoma, Greater Green River, Powder River, San Juan, East Texas and Williston Basins.
	Unless the context requires otherwise, in this report references to (i) “Samson,” “Company,” “we,” “our,” and “us” refer to Samson Resources Corporation and its subsidiaries and (ii) “natural gas” or “gas” include natural gas liquids, which we may refer to as “NGLs”.
	Interim Financial Statements
	The accompanying condensed consolidated financial statements are unaudited. The consolidated balance sheet at December 31, 2013 is derived from our audited consolidated financial statements. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments necessary to present fairly our financial position at June 30, 2014 and our results of operations and cash flows for the relevant interim periods ended June 30, 2014 and 2013. All adjustments are of a normal recurring nature. The results of interim periods are not necessarily indicative of annual results.
	On July 22, 2014, we commenced the exchange offer with respect to our 9.75% Senior Notes due 2020 (the “Senior Notes”). Certain disclosures have been condensed or omitted from these condensed consolidated interim financial statements. Accordingly, these consolidated interim financial statements should be read in conjunction with the information contained in the prospectus relating to such exchange offer, dated as of and filed with the Securities and Exchange Commission (the “SEC”) pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”), on July 22, 2014 (the “Prospectus”).
	Significant Accounting Policies
	As of June 30, 2014, there were no changes in significant accounting policies from those described in the December 31, 2013 audited consolidated financial statements.
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the respective reporting periods. Estimates and assumptions that, in the opinion of management, are significant include oil and natural gas reserves used to compute depletion expense and the full cost ceiling limitation, depletion expense relating to oil and gas properties, allocations of value from unproved properties to proved properties when proved reserves are established or wells are completed, asset retirement obligations, fair value measurements used to record derivatives, employee stock based compensation, impairments of unproved property, accruals for revenue, expenses and capital expenditures, assumptions used to account for loss contingencies, projected compliance with debt covenant requirements and income taxes. We base our estimates on historical experience and on assumptions and information that are believed to be reasonable under the circumstances. Estimates and assumptions about future events and their effects cannot be determined with certainty, and accordingly, these estimates may change as facts and circumstances change. Actual results may differ from the estimates used in the preparation of our consolidated financial statements.
	Reclassifications
	Certain amounts previously reported have been reclassified to conform to the current period presentation. These reclassifications were made in the condensed consolidated statements of cash flows. This reclassification did not impact consolidated net income (loss), shareholders’ equity or total cash flows.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 “Revenue from Contracts with Customers.” ASU 2014-09 creates a comprehensive framework for the recognition of revenue. ASU 2014-09 requires an entity to (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract(s), (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract(s), and (v) recognize revenue when, or as, the entity satisfies a performance obligation. ASU 2014-09 is effective beginning on January 1, 2017 for public entities. We are currently evaluating the potential impact of ASU 2014-09 on our condensed consolidated financial statements.

	Property, plant and equipment, net of accumulated depletion and depreciation	$	6,926,748		$	7,040,932
	Oil and Gas Properties
	We utilize the full cost method of accounting for oil and gas properties. During the three and six months ended June 30, 2014 and 2013, we transferred approximately $168.8 million and $4.7 million, respectively, and $231.6 million and $8.5 million, respectively, in unproved property value to proved property due to acreage expirations, planned divestitures of unproved properties and our assessment of the likelihood that certain acreage positions will be developed.
	We capitalize internal costs that are directly related to the acquisition, exploration and development of oil and gas properties, which are included in proved properties and are subject to depletion. We also capitalize interest costs for properties with exploration and development activities, which are included in unproved oil and gas properties and are excluded from amortization. The following table summarizes capitalized internal costs and capitalized interest expense for the three and six months ended June 30, 2014 and 2013 (in thousands):
		Three Months Ended						Six Months Ended
		June 30,						June 30,
		2014			2013			2014		2013
	Capitalized internal costs, excluding stock compensation	$	7,955		$	8,811		$	15,878	$	16,043
	Capitalized stock compensation		902			1,190			3,525		1,788
	Capitalized interest costs		64,698			84,904			128,344		166,443
		$	73,555		$	94,905		$	147,747	$	184,274
	During the three and six months ended June 30, 2014 and 2013, the net capitalized cost of oil and gas properties subject to depletion exceeded the ceiling amount during the quarterly full cost ceiling test. As a result, we recorded impairment expense associated with our oil and gas properties in the amount of $312.1 million and $11.1 million for the three months ended June 30, 2014 and 2013, respectively, and $312.1 million and $80.3 million for the six months ended June 30, 2014 and 2013, respectively. Our pre-tax impairment expense associated with our oil and gas properties for the six months ended June 30, 2014 and 2013 was increased (decreased) by $8.0 million and $(74.2) million, respectively, as a result of derivatives designated as cash flow hedges.

Derivative Financial Instruments	'
	Note 6. Derivative Financial Instruments
	Objectives and Strategies
	We are exposed to market risk from changes in energy commodity prices related to our crude oil, natural gas and NGL production activities. We utilize commodity-based derivative instruments to manage our exposure to changes in expected future cash flows from forecasted sales of oil, natural gas and NGLs attributable to commodity price risk. These derivatives include fixed price swap agreements, basis swaps and collars containing extension options.
	Accounting Treatment
	We designated a portion of our commodity derivatives as cash flow hedges of the forecasted sales of our oil and natural gas production. The table below summarizes the various methods in which we account for our derivative instruments and the impact on our consolidated financial statements:
			Recognition and Measurement
	Accounting Treatment		Balance Sheet			Statement of Income (Loss)
	Normal purchase/normal sale		Ÿ		Fair value not recorded	Ÿ		Change in fair value not recognized in earnings
	Mark-to-market		Ÿ		Recorded at fair value	Ÿ		Change in fair value recognized in earnings
	Cash flow hedge		Ÿ		Recorded at fair value	Ÿ		Ineffective portion of gain or loss on the derivative instrument is recognized in earnings
		Ÿ	Effective portion of the gain or loss on the derivative instrument is reported initially as a component of accumulated other comprehensive income (loss)	Ÿ	Effective portion of the gain or loss on the derivative instrument is reclassified out of accumulated other comprehensive income (loss) into earnings when the forecasted transaction affects earnings
	For cash flow hedges, we formally document all relationships between hedging instruments and hedged items as well as risk-management objectives. We specifically identify the forecasted transaction that has been designated as the hedged item. We assess the effectiveness of hedging relationships quarterly to determine whether the hedge relationships are highly effective on a retrospective and prospective basis. The agreements and contracts designated as cash flow hedges are expected to be highly effective in offsetting cash flows attributable to the hedged risk during the term of the hedge. However, ineffectiveness could be recognized as a result of locational differences between the hedging derivative and the hedged item.
	Derivatives
	Our natural gas derivatives settle against the last day prompt month New York Mercantile Exchange (“NYMEX”) Henry Hub futures price. Our natural gas basis swaps settle against the respective Inside FERC first of the month index. Our crude oil derivatives settle against the calendar month average of the prompt month NYMEX West Texas Intermediate futures price. NGL fixed price swap agreements settle against the respective Mont Belvieu or Conway Oil Price Information Service calendar month averages.

(a)	Our derivative assets and liabilities are labeled accordingly in the condensed consolidated balance sheets and are presented on a net basis. We net derivative assets and liabilities when a legally enforceable master netting agreement exists between the counterparty to a derivative contract and us. All of our derivatives are entered into with banks that are part of our RBL Revolver (as defined below) or their respective affiliates. As a result, we do not have any margin requirements.
Cash Flow Hedges
We use derivative instruments to hedge the cash flows associated with the anticipated sales of our oil and natural gas production activities. Accumulated other comprehensive loss at June 30, 2014 included $9.6 million, net of tax, related to these cash flow hedges that will be recognized over the next four years as the forecasted transactions affect earnings. If prices remain at current levels, we will recognize $5.7 million in losses, net of income tax, over the next twelve months. For derivatives designated as cash flow hedges, the following table presents separately the pretax cash settlements and unrealized gains and losses included in the condensed consolidated statements of income (loss) and comprehensive income (loss) for the periods presented (in thousands):

	Management evaluates the methods and assumptions in a third party valuation report as part of our process in estimating the fair value of our derivatives. The following methods and assumptions were used to estimate the fair values in the table above:
	Level 2 Fair Value Measurements
	Derivatives—The fair value of oil and natural gas commodity swaps has been calculated utilizing quoted market prices that are observable.
	Level 3 Fair Value Measurements
	Derivatives—The fair value of NGL swaps has been calculated utilizing third party pricing services and discount factors. The fair value of natural gas collars has been calculated utilizing futures prices and market implied volatilities of the underlying futures contracts.
	The following table presents a reconciliation of changes in the fair value of our financial assets and liabilities classified as Level 3 fair value measurements in the fair value hierarchy for the indicated periods (in thousands):

	Other Financial Instruments
	Our cash and cash equivalents are comprised of bank and money market accounts. The carrying values of our cash and cash equivalents, accounts receivable and accounts payable approximate fair value, primarily due to the short-term nature of these instruments. At June 30, 2014 and December 31, 2013, the estimated fair value of our long-term debt, including current maturities, was approximately $3.9 billion and $3.8 billion, respectively. Our measurements are based primarily upon quoted trading prices for our Senior Notes and internal models, and therefore include both Level 2 and Level 3 measurements under the fair value hierarchy.

	Total long-term debt		$	3,750,000	$	3,554,000
	RBL Revolver
	In May 2014, we amended the credit agreement governing the reserve-based revolving credit facility (the “RBL Revolver”) to, among other things, modify the financial performance covenant to provide that we shall maintain:
		•		beginning with the first quarter of 2014 and terminating at the end of 2015, a ratio of consolidated total first lien debt to consolidated EBITDA (each as defined in the credit agreement, with consolidated EBITDA measured on a rolling four-quarter basis) of not more than 1.5 to 1.0 as of the end of each fiscal quarter; and
		•		beginning with the first quarter of 2016, a ratio of consolidated total debt to consolidated EBITDA (each as defined in the credit agreement, with consolidated EBITDA measured on a rolling four-quarter basis) of not more than 4.5 to 1.0 as of the end of each fiscal quarter.
	In addition, the amendment modified the credit agreement governing the RBL Revolver to (i) reduce the borrowing base from approximately $1.8 billion to $1.0 billion and (ii) permit us to incur an additional $500.0 million of second lien debt without a further, related reduction to the borrowing base, subject to certain limitations and conditions. Our borrowing base under the RBL Revolver is based upon our proved reserves and is redetermined semi-annually by our lenders. In addition, the borrowing base may be adjusted pursuant to certain non-scheduled redeterminations, including in connection with certain dispositions of our proved reserves. At June 30, 2014, we had outstanding borrowings of approximately $500.0 million and availability of approximately $498.2 million under the RBL Revolver after giving effect to outstanding letters of credit. During the six months ended June 30, 2014, the weighted average interest rate for borrowings under the RBL Revolver was 2.0%.
	Senior Notes
	In connection with the issuance of the Senior Notes, we entered into a registration rights agreement, which includes certain provisions requiring that we file a registration statement to exchange the Senior Notes for new registered notes to be declared effective within 450 days of the original issue date of the Senior Notes. In accordance with the terms of the registration rights agreement, if we have not exchanged the Senior Notes or if a shelf registration statement covering the resale of the Senior Notes has not been declared effective by the 450th day after the original issue date of the Senior Notes, additional interest shall accrue on the principal amount of the Senior Notes. We began incurring additional interest on the Senior Notes in May 2013. For the six months ended June 30, 2014, our weighted average effective interest rate incurred on our Senior Notes was 10.7%. On July 22, 2014, we commenced the exchange offer with respect to the Senior Notes, and we expect the exchange offer to be completed on or about August 19, 2014, subject to possible extensions by us. Upon the completion of the exchange offer of the Senior Notes, the additional interest will no longer accrue on the Senior Notes.
	Debt Covenants
	Under the RBL Revolver credit agreement, we are subject to the financial performance covenant described above. This covenant may restrict our ability to engage in certain actions, including by potentially limiting our ability to sell assets or make future borrowings under the RBL Revolver or incur other additional indebtedness. Forecasting our compliance with the financial performance covenant in future periods is inherently uncertain. Factors that could impact our future compliance with the financial performance covenant include future realized prices for sales of oil, natural gas and natural gas liquids, estimated future production, returns generated by our capital program, future interest costs, future operating costs, proceeds received from future asset sales and future equity contributions, among others.
	The credit agreements governing the RBL Revolver and our second lien term loan credit facility (the “Second Lien Term Loan”) and the indenture governing the Senior Notes (collectively, the “Debt Agreements”) all contain additional customary non-financial covenants that, among other things, restrict our ability to pay dividends, restrict our ability to sell assets, restrict our ability to make acquisitions or investments, and restrict our ability to incur additional indebtedness. In addition, the Debt Agreements contain reporting and administrative requirements, including, but not limited to, providing financial statements, compliance certificates and other documents to our counterparties to the Debt Agreements under prescribed timelines.
	Subject to any cure periods, the consequences of non-compliance with our debt covenants generally include, but are not limited to, the ability of our counterparties to the Debt Agreements to accelerate our obligation to repay amounts outstanding under our Debt Agreements.

	2011 Stock Incentive Plan
	On April 16, 2012, we implemented the Samson Resources Corporation 2011 Stock Incentive Plan (the “2011 Plan”). The 2011 Plan authorizes the grant of awards in the form of restricted shares, phantom stock, warrants or other securities that are convertible or exercisable into shares of common stock. Employees, members of the Board of Directors, consultants and service providers of Samson are eligible to receive awards under the 2011 Plan. In the second quarter of 2013, we amended the 2011 Plan to increase the total number of securities available to be granted from 10% of the common stock on a fully diluted basis to 98,200,000 securities.
	Stock Options

	Exercisable at June 30, 2014		21,084,030		$2.50 - $7.50		$	3.29				8.2
	Stock options are valued at the date of award and compensation cost is recognized on a straight-line basis, net of estimated forfeitures, over the requisite service period. The compensation cost associated with stock options impacts our accumulated paid in capital. The following table summarizes information about stock based compensation related to stock options for the three and six months ended June 30, 2014 and 2013 (in thousands):
		Three Months Ended June 30,							Six Months Ended June 30,

	Income tax benefit related to stock options	$	3,044		$	2,025			$	7,269			$	3,799
	In calculating the compensation expense for stock options, we estimated the fair value of each grant using the Black-Scholes-Merton option pricing model. Assumptions utilized in the model are shown below:
		Awards issued in		Awards issued in
		2014		2013
	Risk-free interest rate	1.98 - 2.20%		1.35 - 2.25%
	Expected term (years)	7.25		7.25
	Expected volatility	49.70 - 49.86%		47.91 - 49.40%
	Expected dividend yield	—		—
	The risk-free interest rate is based on U.S. Treasury zero-coupon security issuances with remaining terms equal to the expected term. The expected term of the options is based on vesting schedules, consideration of contractual terms and expectations of future employee behaviors. Expected volatilities are based on a combination of historical and implied volatilities of comparable companies.
	The forfeiture rate for non-officer employee stock options issued under the 2011 Plan is 9%. We assumed no future forfeitures of stock options issued to our executive team and 5% for other officers.
	The following table reflects the future stock-based compensation cost to be recognized (either expensed or capitalized) for the nonvested stock option awards that were outstanding at June 30, 2014 (in thousands):
	Remainder of 2014	$	16,217
	2015		31,094
	2016		16,855
	2017		15,327
	2018		4,741
	2019		160
		$	84,394
	Modifications to our outstanding stock options result in additional compensation cost if the fair value of the modified award immediately after the modification exceeds the fair value of the outstanding award immediately before the modification. For vested awards, the modification results in immediate expense recognition. For unvested awards, the additional compensation cost is recognized over the remaining requisite service period. During the first quarter of 2014, we modified the terms of certain stock options issued under the 2011 Plan. The exercise price for all non-officer employee held stock options was changed to $2.50 from the original $5.00 or $4.00 exercise prices established in the original award. In addition, modifications were made to certain stock options held by officers of the Company, which also included reductions in the number of stock options held by our Chief Executive Officer and decreases to the exercise prices of certain stock options held by all officers. After the modifications, the exercise prices for a majority of our outstanding stock options was $2.50 while a portion of our stock options held by our Chief Executive Officer had exercise prices of $4.00, $5.00, and $7.50. The stock option modifications will increase stock compensation expense in future periods. The modifications increased stock compensation expense by $9.0 million after the effects of capitalization for the six months ended June 30, 2014.
	Restricted Stock
	Grants of 10,000,000 shares of restricted stock were made to certain officers during the six months ended June 30, 2014. The shares of restricted stock were granted with a vesting schedule of 20% a year, with the first 20% vesting in April 2015.

	Stock forfeited		—
	Shares outstanding at June 30, 2014		16,400,000
	Vested during period		—
	Restricted stock is valued at the date of award based on the estimated fair value of an unrestricted share reduced by a lack of marketability discount of 15%. Compensation cost is recognized on a straight-line basis over the requisite service period. We assume no future forfeitures of restricted stock issued to our executive team and 5% for other officers. The compensation cost associated with restricted stock impacts our accumulated paid in capital. The following table summarizes information about stock based compensation related to restricted stock for the three and six months ended June 30, 2014 and 2013 (in thousands):

Rental expense is included in general and administrative expenses in the condensed consolidated statements of income (loss) and comprehensive income (loss).
	Other Commercial Commitments
	We have commitments for drilling rigs and related equipment with payments under the contracts accounted for as capital additions to our oil and gas properties. As of June 30, 2014, future payments under these agreements, including rig terminations, are approximately $22.3 million for the remainder of 2014.
	Letters of Credit and Bonds
	As of June 30, 2014, we had outstanding irrevocable letters of credit totaling approximately $1.8 million to guarantee payment of certain marketing related and workers compensation insurance obligations. Additionally, at June 30, 2014, we had approximately $10.6 million in outstanding bonds securing various commitments, such as plugging costs and surface damages.
	Change in Control Agreements
	Effective January 1, 2014, the Company adopted a Change in Control Severance Plan for non-officer employees that applies to eligible employees and a Change in Control Severance Plan for officers (collectively, the “Change in Control Severance Plans”) that applies to all officers except the Chief Executive Officer, who is covered by an employment agreement. The Change in Control Severance Plans provide for the payment of cash compensation and certain other benefits to eligible officers and non-officer employees in the event of a change in control and a qualifying termination of employment. The obligations under the Change in Control Severance Plans are generally based on the terminated employee’s cash compensation, employment tenure, and position within the Company.
	An employment agreement with our Chief Executive Officer provides for the payment of cash compensation and certain other benefits in the event of a severance or change in control depending upon the circumstance.
	Depending on the facts and circumstances associated with a potential change in control, the total payments made pursuant to the Change in Control Severance Plans or employment agreements could be material.

	We are involved in various matters incidental to our operations and business that might give rise to a loss contingency, including, among other things, legal and regulatory proceedings, commercial disputes, claims from royalty, working interest and surface owners, property damage and personal injury claims and environmental or other matters. In addition, we are subject, from time to time, to customary audits and investigations by governmental and tribal authorities regarding the payment and reporting of various taxes, governmental royalties and fees as well as our compliance with unclaimed property (escheatment) requirements and other laws. Unclaimed property laws generally require us to turn over to certain governmental authorities the property of others held by us that has been unclaimed for a specified period of time. In addition, other parties with an interest in wells operated by us have the ability under various contractual agreements to perform audits of our joint interest billing practices where we receive reimbursements from these owners for their share of the costs incurred in connection with the oil and gas properties that we operate.
	We vigorously defend ourselves in these matters, including through the retention of outside counsel where appropriate. A loss contingency may take the form of (i) overtly threatened or pending litigation, (ii) a contractually assumed obligation, or (iii) an unasserted possible claim or assessment. For these matters, we review the merits of the asserted claims, consult with internal and outside counsel as appropriate, assess the degree of probability of an unfavorable outcome, consider possible legal, administrative, litigation, and resolution or settlement strategies, and the availability of insurance coverage, subrogation, indemnities and potential third party liabilities.
	If we determine that an unfavorable outcome or loss of a particular matter is probable and the amount of the loss can be reasonably estimated, we accrue a liability for the contingent obligation, as well as any expected insurance recovery amounts up to the accrued loss. Recovery of any amount in excess of the related recorded contingent loss is recognized if and when all contingencies related to the recovery have been resolved. As new information becomes available as a result of activities in such matters, legal or administrative rulings in similar matters or a change in applicable law, our conclusions regarding the probability of outcomes and estimated loss may change. The impact of subsequent changes to our accruals may have a material effect on our results of operations reported in a single period. We expense all legal fees in the period the expenses are incurred.
	In matters where litigation is pending, it is common and often required for the parties to attend non-binding mediations or settlement conferences. Such mediations or conferences can end in settlement of litigation matters. We have participated in such non-binding mediation and subsequent discussions in an action seeking class certification and damages related to royalty payments for wells located in Oklahoma. In December 2013, a settlement with the plaintiffs was approved by the court. At December 31, 2013, an accrual for this matter was recorded in our consolidated balance sheet. Settlement payments totaling $15.2 million were made in the first quarter of 2014.
	In 2014, in connection with an ongoing audit on behalf of a federal regulator, we began a process of reviewing the manner in which our obligations to make royalty payments for natural gas production on federal leases should be determined. The process involves attempting to determine components of certain fees we pay to transport and process some of our natural gas production associated with individual federal leases and evaluate how each component impacts our royalty payment obligations. We estimate that this process will result in additional royalty payments made related to natural gas production on certain federal leases and have recorded a liability associated with this matter. Estimating the liability is inherently uncertain as each contract associated with individual federal leases has to be analyzed and the estimated fee components will ultimately be subject to approval by our federal regulator. Consequently, it is reasonably possible that a loss exceeding the liability recorded has been incurred and we cannot estimate the range of loss in excess of our recorded liability. However, we do not currently expect our payment of additional royalties will be materially in excess of the liability recorded.
	Also in 2014, an audit of our unclaimed property (escheat) practices in certain states was commenced. As is customary in the industry, we do not expect preliminary audit results to be known for several months.
	As of June 30, 2014, our total accrual for all loss contingencies was $7.0 million, of which $1.3 million was included in oil and natural gas revenues held for distribution and $5.7 million was included in accrued and other current liabilities in our condensed consolidated balance sheet. Because of the uncertainty inherent in estimating probable payments associated with loss contingencies, it is reasonably possible that adjustments to our accrual will change as facts and circumstances change and such changes may be material.

	Income tax provision (benefit)	$	(115,146	)	$	46,032		$	(115,595	)	$	13,647
	Total income tax expense or benefit differed from the amounts computed by applying the U.S. federal income tax rate to net income (loss) from continuing operations before income taxes as a result of the following:
		Three Months Ended June 30,						Six Months Ended June 30,
		2014			2013			2014			2013
	U.S. statutory rate		35%			35%			35%			35%

	Other		0%			0%			0%			0%
			36%			36%			36%			36%
	We evaluated our tax positions and concluded that we have not taken any uncertain tax positions that require an adjustment to the financial statements. Tax penalties and related interest would be charged to the provision for income taxes when uncertain tax positions are recorded in the financial statements. Therefore, there are no related accruals for interest and penalties related to unrecognized tax benefits at June 30, 2014.

Derivative Instruments And Hedging Activities Disclosure [Abstract]	'
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the respective reporting periods. Estimates and assumptions that, in the opinion of management, are significant include oil and natural gas reserves used to compute depletion expense and the full cost ceiling limitation, depletion expense relating to oil and gas properties, allocations of value from unproved properties to proved properties when proved reserves are established or wells are completed, asset retirement obligations, fair value measurements used to record derivatives, employee stock based compensation, impairments of unproved property, accruals for revenue, expenses and capital expenditures, assumptions used to account for loss contingencies, projected compliance with debt covenant requirements and income taxes. We base our estimates on historical experience and on assumptions and information that are believed to be reasonable under the circumstances. Estimates and assumptions about future events and their effects cannot be determined with certainty, and accordingly, these estimates may change as facts and circumstances change. Actual results may differ from the estimates used in the preparation of our consolidated financial statements.
Reclassifications	'
	Reclassifications
	Certain amounts previously reported have been reclassified to conform to the current period presentation. These reclassifications were made in the condensed consolidated statements of cash flows. This reclassification did not impact consolidated net income (loss), shareholders’ equity or total cash flows.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 “Revenue from Contracts with Customers.” ASU 2014-09 creates a comprehensive framework for the recognition of revenue. ASU 2014-09 requires an entity to (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract(s), (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract(s), and (v) recognize revenue when, or as, the entity satisfies a performance obligation. ASU 2014-09 is effective beginning on January 1, 2017 for public entities. We are currently evaluating the potential impact of ASU 2014-09 on our condensed consolidated financial statements.
Derivative Instruments	'
	We are exposed to market risk from changes in energy commodity prices related to our crude oil, natural gas and NGL production activities. We utilize commodity-based derivative instruments to manage our exposure to changes in expected future cash flows from forecasted sales of oil, natural gas and NGLs attributable to commodity price risk. These derivatives include fixed price swap agreements, basis swaps and collars containing extension options.
