Summary Of Significant Accounting Policies | ' |
NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | |
We use accounting policies which reflect industry practices and conform to accounting principles generally accepted in the U.S. (“GAAP”). As used herein, the following acronyms have the following meanings: “FASB” means the Financial Accounting Standards Board; the “Codification” refers to the Accounting Standards Codification, the collected accounting and reporting guidance maintained by the FASB; “ASC” means Accounting Standards Codification and is generally followed by a number indicating a particular section of the Codification; and “ASU” means Accounting Standards Update, followed by an identification number, which are the periodic updates made to the Codification by the FASB. “SEC” means the Securities and Exchange Commission. | |
Principles of Consolidation. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, after eliminating all significant intercompany transactions. The Company’s interest in oil and natural gas exploration and production ventures and partnerships are proportionately consolidated. | |
Use of Estimates. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. | |
Reserve estimates significantly impact depreciation, depletion and amortization expense and potential impairments of oil and natural gas properties and are subject to change based on changes in oil and natural gas prices and trends and changes in estimated reserve quantities. Other significant estimates include those related to oil and natural gas reserves, the value of oil and natural gas properties (including acquisition properties), oil and natural gas revenues, bad debts, asset retirement obligations, derivative contracts, state taxes and contingencies and litigation. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances. We review estimates and underlying assumptions on a regular basis. Actual results may differ from these estimates. | |
Reclassifications. Certain amounts in the 2012 and 2011 consolidated financial statements have been reclassified to conform to the 2013 presentation. The reclassifications had no impact on net income (loss) or partners’ capital (deficit). | |
In 2013 we revised our reporting for natural gas liquids produced in our Oklahoma properties. Whereas we had previously reported all revenues from Oklahoma for 2012 and 2011 as attributable to a single stream of rich natural gas, we began recording revenues for natural gas liquids from Oklahoma separately in 2013. For comparability, we have reclassified approximately $3.3 million in revenues from natural gas to natural gas liquids for the year 2012. For 2011, we have reclassified $5.0 million in natural gas revenues to revenues from natural gas liquids. These reclassifications had no impact on previously reported total revenues, net income, cash flows, or partners’ capital (deficit). | |
Cash and Cash Equivalents. We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. The Company maintains cash balances at financial institutions in the United States of America, which at times exceed federally insured amounts. The Federal Deposit Insurance provides insurance up to $250,000 per depositor. We monitor the financial condition of the financial institutions and have experienced no losses associated with these accounts. Restricted cash in 2012 included a balance on deposit related to deferred payment of certain royalties. | |
Accounts Receivable. Our receivables arise from the sale of oil and natural gas and joint interest owner receivables for properties in which we serve as the operator. This concentration of customers may impact our overall credit risk, either positively or negatively, in that these entities may be similarly affected by changes in economic or other conditions affecting the oil and natural gas industry. Accounts receivable are generally not collateralized. | |
Allowance for Doubtful Accounts. We routinely assess the recoverability of all material trade and other receivables to determine their collectability. We accrue a reserve when, based on the judgment of management, it is probable that a receivable will not be collected and the amount of the reserve can be reasonably estimated. Accounts receivable are shown net of allowance for doubtful accounts of $1.4 million and $0.8 million as of December 31, 2013 and 2012, respectively. | |
Deferred Financing Costs. Deferred financing costs and the amount of discount at which notes payable have been issued (debt discount) are amortized using the straight-line method, which approximates the interest method, over the term of the related debt. For the years ended December 31, 2013, 2012, and 2011, amortization of deferred financing costs included in interest expense amounted to $2.8 million, $2.4 million, and $2.8 million, respectively. Deferred financing costs are listed among our long-term assets, net of accumulated amortization of $12.8 million and $9.9 million at December 31, 2013 and 2012, respectively. | |
Property and Equipment. Oil and natural gas producing activities are accounted for using the successful efforts method of accounting. Under the successful efforts method, lease acquisition costs and all development costs, including unsuccessful development wells, are capitalized. | |
Unproved Properties — Acquisition costs associated with the acquisition of leases are recorded as unproved properties and capitalized as incurred. These consist of costs incurred in obtaining a mineral interest or right in a property, such as a lease, in addition to options to lease, broker fees, recording fees and other similar costs related to activities in acquiring properties. Unproved properties are classified as unproved until proved reserves are discovered, at which time related costs are transferred to proved oil and natural gas properties. | |
Exploration Expense — Exploration expenses, other than exploration drilling costs, are charged to expense as incurred. These expenses include seismic expenditures and other geological and geophysical costs, expired leases, gain or loss on settlement of asset retirement obligations and lease rentals. The costs of drilling exploratory wells and exploratory-type stratigraphic wells are initially capitalized pending determination of whether the well has discovered proved commercial reserves. If the exploratory well is determined to be unsuccessful, the cost of the well is transferred to expense. Exploratory well drilling costs may continue to be capitalized if the reserve quantity is sufficient to justify completion as a producing well and sufficient progress in assessing the reserves and the economic and operating viability of the project is being made. Assessments of such capitalized costs are made quarterly. | |
Proved Oil and Natural Gas Properties — Costs incurred to obtain access to proved reserves and to provide facilities for extracting, treating, gathering, and storing oil and natural gas are capitalized. All costs incurred to drill and equip successful exploratory wells, development wells, development-type stratigraphic test wells, and service wells, including unsuccessful development wells, are capitalized. | |
Impairment — The capitalized costs of proved oil and natural gas properties are reviewed quarterly for impairment following the guidance provided in ASC 360-10-35, “Property, Plant and Equipment, Subsequent Measurement,” or whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset or asset group exceeds its fair market value and is not recoverable. The determination of recoverability is based on comparing the estimated undiscounted future net cash flows at a producing field level to the carrying value of the assets. If the future undiscounted cash flows, based on estimates of anticipated production from proved reserves and future crude oil and natural gas prices and operating costs, are lower than the carrying cost, the carrying cost of the asset or group of assets is reduced to fair value. For our proved oil and natural gas properties, we estimate fair value by discounting the projected future cash flows at an appropriate risk-adjusted discount rate. | |
Our evaluation of the Company’s proved properties resulted in impairment expense of $135.2 million, $90.3 million, and $16.9 million for the years ended December 31, 2013, 2012, and 2011, respectively. | |
In addition, the Company recorded other write-downs and impairment expense of casing and tubing to lower of cost or market, of zero, zero and $162,000 for the years ended December 31, 2013, 2012 and 2011, respectively. | |
Unproved properties are assessed at least annually to determine whether they have been impaired. Individually significant properties are assessed for impairment on a property-by-property basis, while individually insignificant unproved properties may be assessed in the aggregate. If unproved properties are found to be impaired, an impairment allowance is provided and a loss is recognized in the consolidated statement of operations. For the years ended December 31, 2013, 2012 and 2011, impairment expense of unproved properties was $8.0 million, $5.9 million, and $1.8 million, respectively. | |
Management evaluates whether the carrying value of all other long-lived assets has been impaired when circumstances indicate the carrying value of those assets may not be recoverable. This evaluation is based on undiscounted cash flow projections. The carrying amount is not recoverable if it exceeds the undiscounted sum of cash flows expected to result from the use and eventual disposition of the assets. Management considers various factors when determining if these assets should be evaluated for impairment. | |
If the carrying value is not recoverable on an undiscounted basis, the impairment loss is measured as the excess of the asset’s carrying value over its fair value. Management assesses the fair value of long-lived assets using commonly accepted techniques, and may use more than one method, including, but not limited to, recent third party comparable sales, internally developed discounted cash flow analysis and analysis from outside advisors. Significant changes in market conditions resulting from events such as the condition of an asset or a change in management’s intent to utilize the asset would generally require management to reassess the cash flows related to the long-lived assets. For the years ended December 31, 2013, 2012, and 2011, respectively, the Company did not record any impairment expense related to other long-lived assets. | |
Depreciation, Depletion and Amortization — Depreciation, depletion, and amortization (“DD&A”) of capitalized costs of proved oil and natural gas properties is computed using the unit-of-production method based upon estimated proved reserves. Assets are grouped for DD&A on the basis of reasonable aggregation of properties with a common geological structural feature or stratigraphic condition, such as a reservoir or field. The reserve base used to calculate DD&A for leasehold acquisition costs and the cost to acquire proved properties is the sum of proved developed reserves and proved undeveloped reserves. The reserve base used to calculate DD&A for lease and well equipment costs, which include development costs and successful exploration drilling costs, includes only proved developed reserves. | |
DD&A expense for the years ended December 31, 2013, 2012, and 2011 related to oil and natural gas properties was $115.5 million, $106.6 million, and $92.3 million, respectively. | |
Leasehold improvements to offices are depreciated using the straight-line method over the life of the lease. The Company’s drilling rig, which was sold during 2013, was depreciated using the straight-line method of depreciation over a period of approximately fifteen years. Other property and equipment is depreciated using the straight-line method over periods ranging from three to seven years. Depreciation expense for non-oil and gas property and equipment for the years ended December 31, 2013, 2012, and 2011 was $3.1 million, $2.7 million, and $1.9 respectively. | |
Investment. The Company’s investment consists of a 10% ownership interest in a drilling company, Orion Drilling Company, LP (“Orion”). The investment is accounted for under the cost method. Under this method, the Company’s share of earnings or losses of the investment are not included in the statements of operations. | |
Asset Retirement Obligations. We recognize liabilities for the future costs of dismantlement and abandonment of our wells, facilities, and other tangible long-lived assets along with an associated increase in the carrying amount of the related long-lived asset. The fair value of new asset retirement obligations are estimated using expected future costs discounted to present value. The cost of the tangible asset, including the asset retirement cost, is depleted over the useful life of the asset. Accretion expense is recognized as the discounted liability is accreted to its expected settlement value. Asset retirement obligations are subject to revision primarily for changes to the estimated timing and cost of abandonment. | |
Derivative Financial Instruments. We use derivative contracts to hedge the effects of fluctuations in the prices of oil, natural gas and interest rates. We account for such derivative instruments in accordance with ASC 815, “Derivatives and Hedging,” which establishes accounting and disclosure requirements for derivative instruments and requires them to be measured at fair value and recorded as assets or liabilities in the consolidated balance sheets (see Note 5 for information on fair value). | |
Under ASC 815, hedge accounting is used to defer recognition of unrealized changes in the fair value of such financial instruments, for those contracts which qualify as fair value or cash flow hedges, as defined in the guidance. Historically, we have not designated any of our derivative contracts as fair value or cash flow hedges. Accordingly, the unrealized changes in fair value of the contracts are included in earnings in the period of the change as “Unrealized gain (loss) — oil and natural gas derivative contracts” for oil and natural gas contracts, and in interest expense for interest derivative contracts. Realized gains and losses are recorded in income in the period of settlement, and included in the related revenue account or in interest expense. Cash flows from settlements of derivative contracts are classified with the income or expense item to which such settlements directly relate. | |
Income Taxes. The Company has elected under the Internal Revenue Code provisions to be treated as individual partnerships for tax purposes. Accordingly, items of income, expense, gains and losses flow through to the partners and are taxed at the partner level. Accordingly, no tax provision for federal income taxes is included in the consolidated financial statements. | |
The Company is subject to the Texas margin tax, which is considered a state income tax, and is included in “Benefit from (provision for) state income tax” on the consolidated statements of operations. The Company records state income tax (current and deferred) based on taxable income, as defined under the rules for the margin tax. | |
We follow guidance issued by the FASB in accounting for uncertainty in income taxes. This guidance clarifies the accounting for income taxes by prescribing the minimum recognition threshold an income tax position is required to meet before being recognized in the consolidated financial statements and applies to all income tax positions. Each income tax position is assessed using a two step process. A determination is first made as to whether it is more likely than not that the income tax position will be sustained, based upon technical merits, upon examination by the taxing authorities. If the income tax position is expected to meet the more likely than not criteria, the benefit recorded in the consolidated financial statements equals the largest amount that is greater than 50% likely to be realized upon its ultimate settlement. | |
We have considered our exposure under the standard at both the federal and state tax levels. We have not recorded any liabilities for uncertain tax positions as of December 31, 2013 and 2012. We record income tax, related interest, and penalties, if any, as a component of income tax expense. We did not incur any interest or penalties on income taxes for the years ended December 31, 2013, 2012, or 2011. | |
The Company’s tax returns for the years ended December 31, 2009 forward remain open for examination. None of the Company’s federal or state tax returns are currently under examination by the relevant authorities. | |
Revenue Recognition. We recognize oil, natural gas and natural gas liquids revenues when products are delivered at a fixed or determinable price, title has transferred and collectability is reasonably assured. We use the sales method of accounting for recognition of natural gas imbalances. Revenue from drilling rigs has been recorded when services were performed. | |
Fair Value of Financial Instruments. The fair value of cash, accounts receivable and current liabilities approximate book value due to their short-term nature. The estimate of fair value of long-term debt under our credit facility is not considered to be materially different from carrying value due to market rates of interest. The fair value of the debt to our founder is not practicable to determine. We have estimated the fair value of our $450 million senior notes payable at $482.6 million on December 31, 2013. Derivative financial instruments are carried at fair value. See Note 5 for further information on fair values of financial instruments. See Note 9 for information on long-term debt. | |
Acquisitions. Acquisitions are accounted for as purchases using the acquisition method of accounting. Accordingly, the results of operations are included in our consolidated statements of operations from the closing date of the acquisitions. Purchase prices are allocated to acquired assets and assumed liabilities based on their estimated fair value at the time of the acquisition. | |
Recent Accounting Pronouncements | |
In January 2013 we adopted ASU No. 2011-11, which increases disclosures about offsetting assets and liabilities. New disclosures are required to enable users of financial statements to understand significant quantitative differences in balance sheets prepared under GAAP and International Financial Reporting Standards (IFRS) related to the offsetting of financial instruments. The additional disclosures are included in Note 6. | |
In February 2013, the FASB issued ASU No. 2013-04. The guidance requires an entity that is joint and severally liable to measure the obligation as the sum of the amount the entity has agreed with co-obligors to pay and any additional amount it expects to pay on behalf of one or more co-obligors. Required disclosures include a description of the nature of the arrangement, how the liability arose, the relationship with co-obligors and the terms and conditions of the arrangement. ASU No. 2013-04 is effective for annual and interim reporting periods beginning after December 15, 2013. We do not expect the adoption of this pronouncement to have a material impact on our consolidated financial statements. | |

Stone Acquisition | ||||||
On October 1, 2013 we closed a transaction to purchase certain producing properties in South Louisiana from Stone Energy Offshore, L.L.C. (“Stone”) for cash consideration of approximately $45 million plus related abandonment costs, which was later modified through settlement adjustments to approximately $42 million cash. The purchase price was funded with borrowings under our senior secured revolving credit facility. This purchase increases our working interest in numerous wells in our Weeks Island field and adds several properties in which we previously had no working interest. Total estimated net proved reserves associated with the acquisition were 1.8 million BOE as of the effective date of July 1, 2013. | ||||||

Sydson and TODD Acquisitions | ||||||
In 2011, we purchased certain oil and natural gas assets from Sydson Energy and certain of its related parties (“Sydson”) for a total of $28.4 million. We also purchased certain properties from Texas Oil Distribution & Development, Inc. and Matrix Petroleum LLC and certain other parties (“TODD”) for a total of $23.4 million. Funding for both acquisitions was provided through our credit facility. Results of the acquisitions are included in our consolidated statements of operations from the respective acquisition dates for Sydson and TODD of April 21, 2011 and June 17, 2011. Unaudited pro forma revenues and net income for 2011 would have been $357.4 million and $67.1 million, respectively, had the Sydson and TODD acquisitions occurred as of the beginning of that year. | ||||||
Hilltop Divestiture | ||||||
On October 2, 2013 we closed the sale of certain of our properties in East Texas to Cubic Oil, Inc., comprising a portion of our Hilltop field (“Hilltop divestiture”). The properties sold were primarily producers of dry natural gas located in Leon County, Texas. As of July 1, 2013, estimated net proved reserves associated with these properties were 11.2 Bcfe. The cash purchase price was approximately $19 million (net of costs of the sale). There was no material gain on the sale. | ||||||

NOTE 5 — FAIR VALUE DISCLOSURES | ||||||||||||
The Company follows ASC 820, “Fair Value Measurements and Disclosure.” ASC 820 provides a hierarchy of fair value measurements, based on the inputs to the fair value estimation process. It requires disclosure of fair values classified according to defined “levels,” which are based on the reliability of the evidence used to determine fair value, with Level 1 being the most reliable and Level 3 the least. Level 1 evidence consists of observable inputs, such as quoted prices in an active market. Level 2 inputs typically correlate the fair value of the asset or liability to a similar, but not identical item which is actively traded. Level 3 inputs include at least some unobservable inputs, such as valuation models developed using the best information available in the circumstances. | ||||||||||||
We utilize the modified Black-Scholes and the Turnbull Wakeman option pricing models to estimate the fair value of oil and natural gas derivative contracts. Inputs to these models include observable inputs from the New York Mercantile Exchange (NYMEX) and other exchanges for futures contracts, and inputs derived from NYMEX observable inputs, such as implied volatility of oil and natural gas prices. We have classified the fair values of all our oil and natural gas derivative contracts as Level 2. | ||||||||||||
The fair value of our interest rate derivative contracts, which expired in 2012, was calculated using the Black-Scholes option pricing model and is also considered a Level 2 fair value. | ||||||||||||
Our senior notes are carried at historical cost, net of amortized discount; we estimate the fair value of the senior notes for disclosure purposes (see Note 2). This estimation is based on the most recent trading values of the notes at or near the reporting date, a Level 1 classification. | ||||||||||||
Oil and natural gas properties are subject to impairment testing and potential impairment write down as described in Note 2. Oil and natural gas properties with a carrying amount of $237.2 million were written down to their fair value of $94.0 million, resulting in an impairment charge of $143.2 million for the year ended December 31, 2013. Oil and natural gas properties with a carrying amount of $363.7 million were written down to their fair value of $267.5 million, resulting in an impairment charge of $96.2 million for the year ended December 31, 2012. Oil and natural gas properties with a carrying amount of $35.2 million were written down to their fair value of $16.5 million, resulting in an impairment charge of $18.7 million for the year ended December 31, 2011. The impairment analysis is based on the estimated discounted future cash flows for those properties. Significant Level 3 assumptions used in the calculation of estimated discounted cash flows included our estimate of future oil and natural gas prices, production costs, development expenditures, estimated quantities and timing of production of proved reserves, appropriate risk-adjusted discount rates, and other relevant data. | ||||||||||||
In addition, other equipment, included in oil and gas properties, was impaired zero, zero, and $162,000 for the years ended December 31, 2013, 2012 and 2011, respectively, based on market information for similar products, which is a Level 3 value. | ||||||||||||
In connection with the Stone acquisition in 2013 we recorded oil and natural gas properties with a fair value of $47.5 million. In connection with the Sydson and TODD acquisitions in 2011, we recorded oil and natural gas properties with a fair value of $28 million and $23 million, respectively. Significant Level 3 inputs used were the same as those used in determining impairments based on estimated discounted cash flows for the acquired properties. | ||||||||||||
New additions to asset retirement obligations result from estimations for new properties, and fair values for them are categorized as Level 3. Such estimations are based on present value techniques which utilize company-specific information for such inputs as cost and timing of plug and abandonment of wells and facilities. We recorded a total of $6.5 million in additions to asset retirement obligations measured at fair value for the year ended December 31, 2013. We recorded a total of $2.3 million in additions to asset retirement obligations measured at fair value for the year ended December 31, 2012. | ||||||||||||
The following table presents information about our financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2013 and 2012, and indicates the fair value hierarchy of the valuation techniques we utilized to determine such fair value: | ||||||||||||

NOTE 6 — DERIVATIVE FINANCIAL INSTRUMENTS | ||||||||||||||
We account for our derivative contracts under the provisions of ASC 815, “Derivatives and Hedging.” We have entered into forward-swap contracts and collar contracts to reduce our exposure to price risk in the spot market for oil and natural gas. We also utilize financial basis swap contracts, which address the price differential between market-wide benchmark prices and other benchmark pricing referenced in certain of our crude oil and natural gas sales contracts. Substantially all of our hedging agreements are executed by affiliates of the lenders under our credit facility described in Note 9 below, and are collateralized by the security interests of the respective affiliated lenders in certain of our assets under the credit facility. The contracts settle monthly and are scheduled to coincide with either oil production equivalent to barrels (Bbl) per month or gas production equivalent to volumes in millions of British thermal units (MMBtu) per month. The contracts represent agreements between us and the counter-parties to exchange cash based on a designated price, or in the case of financial basis hedging contracts, based on a designated price differential between various benchmark prices. Cash settlement occurs monthly based on the specified price benchmark. We have not designated any of our derivative contracts as fair value or cash flow hedges; accordingly we use mark-to-market accounting, recognizing unrealized gains and losses in the consolidated statement of operations at each reporting date. Realized gains and losses on commodities hedging contracts are included in oil and natural gas revenues. | ||||||||||||||
From time to time, we enter into interest rate swap agreements with financial institutions to mitigate the risk of loss due to changes in interest rates. The interest rate swaps are not designated as cash flow hedges in accordance with ASC 815. Both realized gains and losses from settlement and unrealized gains and losses from changes in the fair market value of the interest rate swaps are included in interest expense. | ||||||||||||||
No derivative contracts have been entered into for trading purposes, and we typically hold each instrument to maturity. | ||||||||||||||
The second table below provides information on the location and amounts of realized and unrealized gains and losses on derivatives included in the consolidated statement of operations for each of the years ended December 31, 2013 and 2012. | ||||||||||||||
Derivative contracts are subject to master netting arrangements and are presented on a net basis in the consolidated balance sheets. This netting can cause derivative assets to be ultimately presented in a (liability) account on the consolidated balance sheets. Likewise, derivative (liabilities) could be presented in an asset account. | ||||||||||||||

Although our counterparties provide no collateral, the master derivative agreements with each counterparty effectively allow the Company, so long as it is not a defaulting party, after a default or the occurrence of a termination event, to set-off an unpaid hedging agreement receivable against the interest of the counterparty in any outstanding balance under the credit facility. If a counterparty were to default in payment of an obligation under the master derivative agreements, we could be exposed to commodity price fluctuations, and the protection intended by the hedge could be lost. The value of our derivative financial instruments would be impacted. | ||||||||||||||

Credit Facility. On May 13, 2010, we entered into a Sixth Amended and Restated Credit Agreement (as amended, the “credit facility”). The credit facility matures on May 23, 2016 and is secured by substantially all of our oil and gas properties. The credit facility borrowing base is redetermined periodically and, as of December 31, 2013, the borrowing base under the facility was $385.0 million. The credit facility bears interest at LIBOR plus applicable margins between 2.00% and 2.75% or a “Reference Rate,” which is based on the prime rate of Wells Fargo Bank, N. A., plus a margin ranging from 1.00% to 1.75%, depending on the utilization of our borrowing base. The rate was 2.75% as of December 31, 2013 and 2.33% as of December 31, 2012. | ||||||
Senior Notes. We have $450 million in outstanding registered senior notes due October 15, 2018 that carry a stated interest rate of 9.625% and an effective interest rate of 9.783%. Interest is payable semi-annually each April 15th and October 15th. The senior notes are unsecured and are general obligations of the Company, and effectively rank junior to any of our existing or future secured indebtedness, which includes the credit facility. The senior notes are unconditionally guaranteed on a senior unsecured basis by each of our material subsidiaries. The balance is presented net of unamortized discount of $2.4 million and $2.9 million at December 31, 2013 and December 31, 2012, respectively. | ||||||
The senior notes contain an optional redemption provision available beginning October 15, 2014 allowing us to retire the principal outstanding, in whole or in part, at 104.813%. Additional optional redemption provisions allow for retirement at 102.406% and 100.0% beginning on each of October 15, 2015 and 2016, respectively. Prior to October 15, 2014, we may redeem the senior notes in whole or in part at a price equal to 100 percent of the principal amount plus a specified make-whole premium and accrued and unpaid interest to the applicable redemption date. | ||||||
Notes Payable to Founder. We have notes payable to our founder which bear simple interest at 10% with a balance of $23.3 million and $22.1 million at December 31, 2013 and December 31, 2012, respectively. As of December 31, 2013, the notes had a maturity date of December 31, 2018. Interest and principal are payable at maturity. These founder notes are unsecured and are subordinate to all debt. Interest on the notes payable to our founder amounted to $1.2 million during each of 2013, 2012, and 2011. Such amounts have been added to the balance of the founder notes. | ||||||

Board of Commissioners of the Southeast Louisiana Flood Protection Authority – East: On July 24, 2013, the Board of Commissioners of the Southeast Louisiana Flood Protection Authority – East sued us and approximately 100 other energy companies for long-term damage to the wetlands in southeast Louisiana. Case No. 2013-6911 was filed in state court and subsequently remanded to federal court. The plaintiff seeks damages and injunctive relief in the form of abatement and restoration of wetlands, alleging that the activities of the oil and gas industry over the past century have contributed significantly to the degradation of the wetlands that protect the populated areas in and around New Orleans from storm surge and other extreme weather effects. The plaintiff alleges damages from increased costs of providing man-made storm protection structures, and emphasizes the destructive effect of canals built by the oil and gas industry. Legal arguments include breach of the restoration and maintenance clauses of contracts with the State of Louisiana for drilling, dredging, and right-of-way agreements for pipelines. Other legal arguments include negligence, strict liability, natural servitude of drain, public nuisance and private nuisance. Our wholly-owned subsidiary The Meridian Resource Company, LLC is named as a defendant with 32 wells, two dredging permits and four right of way agreements in the relevant area. Almost all of these wells are inactive. | |||
The overall exposure related to this lawsuit is not currently determinable. While an adverse judgment against us might be possible, we intend to vigorously defend the case. We have not provided any amount for this matter in our financial statements at December 31, 2013. | |||
Environmental claims: Various landowners have sued our wholly owned subsidiary The Meridian Resource Corporation and its subsidiaries (“Meridian”), which we acquired in 2010, in lawsuits concerning several fields in which Meridian has had operations. The lawsuits seek injunctive relief and other relief, including unspecified amounts in both actual and punitive damages for alleged breaches of mineral leases and alleged failure to restore the plaintiffs’ lands from alleged contamination and otherwise from Meridian’s oil and natural gas operations. We are unable to express an opinion with respect to the likelihood of an unfavorable outcome of the various environmental claims or to estimate the amount or range of potential loss should the outcome be unfavorable. Therefore, we have not provided any amount for these claims in our consolidated financial statements at December 31, 2013. | |||
Due to the nature of our business, some contamination of the real estate property owned or leased by us is possible. Environmental site assessments of the property would be necessary to adequately determine remediation costs, if any. Management has established a liability for soil contamination in Florida of $1.1 million at December 31, 2013 and $1.0 million at December 31, 2012, based on our undiscounted engineering estimates. The obligations are included in other long-term liabilities in the accompanying consolidated balance sheets. No accrual for environmental claims has been made other than the balance noted above. | |||
Title/lease disputes: Title and lease disputes may arise in the normal course of our operations. These disputes are usually small but could result in an increase or decrease in reserves once a final resolution to the title dispute is made. | |||
Other contingencies: We are subject to legal proceedings, claims and liabilities arising in the ordinary course of business. The outcome cannot be reasonably estimated; however, in the opinion of management, such litigation and claims will be resolved without material adverse effect on our financial position, results of operations or cash flows. Accruals for losses associated with litigation are made when losses are deemed probable and can be reasonably estimated. | |||
We have a contingent commitment to pay an amount up to a maximum of approximately $2.4 million for properties acquired in 2008. The additional purchase consideration will be paid if certain product price conditions are met. | |||
Commitments | |||
Office and Equipment Leases: We lease office space, as well as certain field equipment such as compressors, under long-term operating lease agreements. The lease for our main office will expire in 2022. Any initial rent-free months are amortized over the life of the lease. Equipment leases are generally for four years or less. Rent expense, including office space and compressors, for the years ended December 31, 2013, 2012, and 2011 amounted to approximately $5.3 million, $4.5 million, and $4.3 million, respectively. | |||
At December 31, 2013, future base rentals for non-cancelable operating leases are as follows (dollars in thousands): | |||

NOTE 12 — MAJOR CUSTOMERS | |
We sell our oil and natural gas primarily under a contract with ARM Energy Management, LLC (“AEM”). Alta Mesa is a part owner of AEM at less than 10%. AEM purchases our natural gas and sells it under short-term contracts generally with month-to-month pricing based on published regional indices, with differentials for transportation taken into account. AEM purchases our oil and sells it under short-term contracts with monthly pricing based on regional prices, adjusted for transportation, location, and quality. AEM remits monthly proceeds of its sales to us, and receives a 1% marketing fee. Sales to AEM commenced in June 2013. The agreement will terminate in 2018, with additional provisions for extensions beyond five years, and for early termination beginning in January 2015. During the second half of 2013, we sold the majority of our production from operated fields to AEM. Production from non-operated fields, the most significant of which were our Eagleville oil field in South Texas and our Hilltop natural gas field in East Texas, was marketed on our behalf by the operators of those properties. Production from Eagleville is sold by Murphy Oil Corporation (“Murphy”), the operator of that property. Production from Hilltop is sold primarily by EnCana Oil & Gas (USA), Inc. (“EnCana”), the operator of a substantial portion of the wells in that field. | |
For the year ended December 31, 2013, revenues from AEM were $61.3 million, or 16% of total revenue excluding hedging activities. Based on revenues excluding hedging activities, three other major customers accounted for 10% or more of those revenues individually, with contributions of $119.3 million (Murphy), $53.9 million (Shell Trading (US) Company), and $42.0 million (Plains Marketing and Transportation, Inc.) On the same basis, for the year ended December 31, 2012, three major customers accounted for 10% or more of those revenues individually, with contributions of $63.3 million (Shell Trading (US) Company), $50.1 million (Murphy), and $44.8 million (EnCana). On the same basis, for the year ended December 31, 2011, two major customers accounted for 10% or more of those revenues individually, with contributions of $67.7 million (Shell Trading (US) Company), and | |
$40.8 million (EnCana). We believe that the loss of any of our significant direct or indirect customers, or of AEM, would not have a material adverse effect on us because alternative purchasers are readily available. | |

NOTE 14 — SIGNIFICANT RISKS AND UNCERTAINTIES | |
Our business makes us vulnerable to changes in wellhead prices of crude oil and natural gas. Such prices have been volatile in the past and can be expected to be volatile in the future. By definition, the value of proved reserves is based on recent oil and natural gas prices. Price declines reduce the estimated value of proved reserves and increase annual amortization expense (which is based on proved reserves). We mitigate some of this vulnerability by entering into oil and natural gas price derivative contracts. See Note 6. | |

Disposition of Asset | ||||||
On March 25, 2014 we closed the sale of certain of our properties located primarily in Karnes County, Texas to Memorial Production Partners LP, comprising a portion of our Eagleville field (“Eagleville divestiture”). The properties sold included a working interest in all of our 112 producing wells and five wells in which we own an overriding royalty interest as of the effective date of January 1, 2014. We retained a net profits interest in these wells based on 50% of our original working interest in 2014, declining to 30% in 2015, 15% in 2016, and zero in 2017. Also included in the sale was a 30% undivided interest in all our Eagleville mineral leases and interests, and 30% of our working interest in all our wells in progress on December 31, 2013 or drilled after January 1, 2014. The cash purchase price was $173 million. The purchase and sale agreement provides for customary adjustments to the purchase price for revenues and expenses incurred after the effective date. Cash received was utilized to pay down borrowings under our senior secured revolving credit facility. | ||||||
As of January 1, 2014, estimated net proved reserves associated with the sold portion of these properties were approximately 7.7 MMBOE. | ||||||
Unaudited pro forma revenues and net income are presented below as if the sale occurred on January 1, 2012. This data is presented for informational purposes only, and is based on certain assumptions that we believe are reasonable, and do not purport to represent our financial condition or our results of operations had the Eagleville divestiture actually occurred on January 1, 2013, or to project the results for any future date or period. | ||||||

Borrowing Base | ||||||
In connection with the partial sale of the Eagleville field, our borrowing base under our credit facility was reduced to $285 million on March 25, 2014. | ||||||
Partnership Changes | ||||||
On March 25, 2014, Highbridge Principal Strategies LLC (“Highbridge”) invested in AMIH and enabled AMIH to complete a $350 million recapitalization. Highbridge received convertible PIK preferred stock in AMIH and senior PIK notes from AMIH. We expanded our Board of Directors to include one member nominated by Highbridge and one new employee member, our Chief Financial Officer, Michael A. McCabe. AMIH remains our sole Class B partner. | ||||||
Our partnership agreement was revised to provide, among other things, that all distributions under the amended partnership agreement shall first be made to holders of Class B Units, until all principal and interest has been extinguished under the senior PIK notes issued to Highbridge. After such extinguishment of the senior PIK notes, distributions shall then be made to holders of Class A and Class B Units pursuant to the distribution formulas set forth in the amended partnership agreement. | ||||||

Standardized Measure of Discounted Future Net Cash Flows | |||||||||||
The information that follows has been developed pursuant to ASC 932-235 and utilizes reserve and production data prepared by us. Reserve estimates are inherently imprecise and estimates of new discoveries are less precise than those of producing oil and natural gas properties. Accordingly, these estimates are expected to change as future information becomes available. | |||||||||||
Future cash inflows as of December 31, 2013 and 2012 were calculated using an un-weighted arithmetic average of oil and natural gas prices in effect on the first day of each month in the respective year, except where prices are defined by contractual arrangements. Operating costs, production and ad valorem taxes and future development costs are based on current costs with no escalation. | |||||||||||
Actual future prices and costs may be materially higher or lower. Actual future net revenues also will be affected by factors such as actual production, supply and demand for oil and natural gas, curtailments or increases in consumption by natural gas purchasers, changes in governmental regulations or taxation and the impact of inflation on costs. | |||||||||||

Summary Of Significant Accounting Policies (Policy) | 12 Months Ended |
Dec. 31, 2013 | |
Summary Of Significant Accounting Policies [Abstract] | ' |
Principles Of Consolidation | ' |
Principles of Consolidation. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, after eliminating all significant intercompany transactions. The Company’s interest in oil and natural gas exploration and production ventures and partnerships are proportionately consolidated. | |
Use Of Estimates | ' |
Use of Estimates. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. | |
Reserve estimates significantly impact depreciation, depletion and amortization expense and potential impairments of oil and natural gas properties and are subject to change based on changes in oil and natural gas prices and trends and changes in estimated reserve quantities. Other significant estimates include those related to oil and natural gas reserves, the value of oil and natural gas properties (including acquisition properties), oil and natural gas revenues, bad debts, asset retirement obligations, derivative contracts, state taxes and contingencies and litigation. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances. We review estimates and underlying assumptions on a regular basis. Actual results may differ from these estimates. | |
Reclassifications | ' |
Reclassifications. Certain amounts in the 2012 and 2011 consolidated financial statements have been reclassified to conform to the 2013 presentation. The reclassifications had no impact on net income (loss) or partners’ capital (deficit). | |
In 2013 we revised our reporting for natural gas liquids produced in our Oklahoma properties. Whereas we had previously reported all revenues from Oklahoma for 2012 and 2011 as attributable to a single stream of rich natural gas, we began recording revenues for natural gas liquids from Oklahoma separately in 2013. For comparability, we have reclassified approximately $3.3 million in revenues from natural gas to natural gas liquids for the year 2012. For 2011, we have reclassified $5.0 million in natural gas revenues to revenues from natural gas liquids. These reclassifications had no impact on previously reported total revenues, net income, cash flows, or partners’ capital (deficit). | |
Cash And Cash Equivalents | ' |
Cash and Cash Equivalents. We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. The Company maintains cash balances at financial institutions in the United States of America, which at times exceed federally insured amounts. The Federal Deposit Insurance provides insurance up to $250,000 per depositor. We monitor the financial condition of the financial institutions and have experienced no losses associated with these accounts. Restricted cash in 2012 included a balance on deposit related to deferred payment of certain royalties. | |
Accounts Receivable | ' |
Accounts Receivable. Our receivables arise from the sale of oil and natural gas and joint interest owner receivables for properties in which we serve as the operator. This concentration of customers may impact our overall credit risk, either positively or negatively, in that these entities may be similarly affected by changes in economic or other conditions affecting the oil and natural gas industry. Accounts receivable are generally not collateralized. | |
Allowance For Doubtful Accounts | ' |
Allowance for Doubtful Accounts. We routinely assess the recoverability of all material trade and other receivables to determine their collectability. We accrue a reserve when, based on the judgment of management, it is probable that a receivable will not be collected and the amount of the reserve can be reasonably estimated. Accounts receivable are shown net of allowance for doubtful accounts of $1.4 million and $0.8 million as of December 31, 2013 and 2012, respectively. | |
Deferred Financing Costs | ' |
Deferred Financing Costs. Deferred financing costs and the amount of discount at which notes payable have been issued (debt discount) are amortized using the straight-line method, which approximates the interest method, over the term of the related debt. For the years ended December 31, 2013, 2012, and 2011, amortization of deferred financing costs included in interest expense amounted to $2.8 million, $2.4 million, and $2.8 million, respectively. Deferred financing costs are listed among our long-term assets, net of accumulated amortization of $12.8 million and $9.9 million at December 31, 2013 and 2012, respectively. | |
Property And Equipment | ' |
Property and Equipment. Oil and natural gas producing activities are accounted for using the successful efforts method of accounting. Under the successful efforts method, lease acquisition costs and all development costs, including unsuccessful development wells, are capitalized. | |
Unproved Properties — Acquisition costs associated with the acquisition of leases are recorded as unproved properties and capitalized as incurred. These consist of costs incurred in obtaining a mineral interest or right in a property, such as a lease, in addition to options to lease, broker fees, recording fees and other similar costs related to activities in acquiring properties. Unproved properties are classified as unproved until proved reserves are discovered, at which time related costs are transferred to proved oil and natural gas properties. | |
Exploration Expense — Exploration expenses, other than exploration drilling costs, are charged to expense as incurred. These expenses include seismic expenditures and other geological and geophysical costs, expired leases, gain or loss on settlement of asset retirement obligations and lease rentals. The costs of drilling exploratory wells and exploratory-type stratigraphic wells are initially capitalized pending determination of whether the well has discovered proved commercial reserves. If the exploratory well is determined to be unsuccessful, the cost of the well is transferred to expense. Exploratory well drilling costs may continue to be capitalized if the reserve quantity is sufficient to justify completion as a producing well and sufficient progress in assessing the reserves and the economic and operating viability of the project is being made. Assessments of such capitalized costs are made quarterly. | |
Proved Oil and Natural Gas Properties — Costs incurred to obtain access to proved reserves and to provide facilities for extracting, treating, gathering, and storing oil and natural gas are capitalized. All costs incurred to drill and equip successful exploratory wells, development wells, development-type stratigraphic test wells, and service wells, including unsuccessful development wells, are capitalized. | |
Impairment — The capitalized costs of proved oil and natural gas properties are reviewed quarterly for impairment following the guidance provided in ASC 360-10-35, “Property, Plant and Equipment, Subsequent Measurement,” or whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset or asset group exceeds its fair market value and is not recoverable. The determination of recoverability is based on comparing the estimated undiscounted future net cash flows at a producing field level to the carrying value of the assets. If the future undiscounted cash flows, based on estimates of anticipated production from proved reserves and future crude oil and natural gas prices and operating costs, are lower than the carrying cost, the carrying cost of the asset or group of assets is reduced to fair value. For our proved oil and natural gas properties, we estimate fair value by discounting the projected future cash flows at an appropriate risk-adjusted discount rate. | |
Our evaluation of the Company’s proved properties resulted in impairment expense of $135.2 million, $90.3 million, and $16.9 million for the years ended December 31, 2013, 2012, and 2011, respectively. | |
In addition, the Company recorded other write-downs and impairment expense of casing and tubing to lower of cost or market, of zero, zero and $162,000 for the years ended December 31, 2013, 2012 and 2011, respectively. | |
Unproved properties are assessed at least annually to determine whether they have been impaired. Individually significant properties are assessed for impairment on a property-by-property basis, while individually insignificant unproved properties may be assessed in the aggregate. If unproved properties are found to be impaired, an impairment allowance is provided and a loss is recognized in the consolidated statement of operations. For the years ended December 31, 2013, 2012 and 2011, impairment expense of unproved properties was $8.0 million, $5.9 million, and $1.8 million, respectively. | |
Management evaluates whether the carrying value of all other long-lived assets has been impaired when circumstances indicate the carrying value of those assets may not be recoverable. This evaluation is based on undiscounted cash flow projections. The carrying amount is not recoverable if it exceeds the undiscounted sum of cash flows expected to result from the use and eventual disposition of the assets. Management considers various factors when determining if these assets should be evaluated for impairment. | |
If the carrying value is not recoverable on an undiscounted basis, the impairment loss is measured as the excess of the asset’s carrying value over its fair value. Management assesses the fair value of long-lived assets using commonly accepted techniques, and may use more than one method, including, but not limited to, recent third party comparable sales, internally developed discounted cash flow analysis and analysis from outside advisors. Significant changes in market conditions resulting from events such as the condition of an asset or a change in management’s intent to utilize the asset would generally require management to reassess the cash flows related to the long-lived assets. For the years ended December 31, 2013, 2012, and 2011, respectively, the Company did not record any impairment expense related to other long-lived assets. | |
Depreciation, Depletion and Amortization — Depreciation, depletion, and amortization (“DD&A”) of capitalized costs of proved oil and natural gas properties is computed using the unit-of-production method based upon estimated proved reserves. Assets are grouped for DD&A on the basis of reasonable aggregation of properties with a common geological structural feature or stratigraphic condition, such as a reservoir or field. The reserve base used to calculate DD&A for leasehold acquisition costs and the cost to acquire proved properties is the sum of proved developed reserves and proved undeveloped reserves. The reserve base used to calculate DD&A for lease and well equipment costs, which include development costs and successful exploration drilling costs, includes only proved developed reserves. | |
DD&A expense for the years ended December 31, 2013, 2012, and 2011 related to oil and natural gas properties was $115.5 million, $106.6 million, and $92.3 million, respectively. | |
Leasehold improvements to offices are depreciated using the straight-line method over the life of the lease. The Company’s drilling rig, which was sold during 2013, was depreciated using the straight-line method of depreciation over a period of approximately fifteen years. Other property and equipment is depreciated using the straight-line method over periods ranging from three to seven years. Depreciation expense for non-oil and gas property and equipment for the years ended December 31, 2013, 2012, and 2011 was $3.1 million, $2.7 million, and $1.9 respectively. | |
Investment | ' |
Investment. The Company’s investment consists of a 10% ownership interest in a drilling company, Orion Drilling Company, LP (“Orion”). The investment is accounted for under the cost method. Under this method, the Company’s share of earnings or losses of the investment are not included in the statements of operations. | |
Asset Retirement Obligations | ' |
Asset Retirement Obligations. We recognize liabilities for the future costs of dismantlement and abandonment of our wells, facilities, and other tangible long-lived assets along with an associated increase in the carrying amount of the related long-lived asset. The fair value of new asset retirement obligations are estimated using expected future costs discounted to present value. The cost of the tangible asset, including the asset retirement cost, is depleted over the useful life of the asset. Accretion expense is recognized as the discounted liability is accreted to its expected settlement value. Asset retirement obligations are subject to revision primarily for changes to the estimated timing and cost of abandonment. | |
Derivative Financial Instruments | ' |
Derivative Financial Instruments. We use derivative contracts to hedge the effects of fluctuations in the prices of oil, natural gas and interest rates. We account for such derivative instruments in accordance with ASC 815, “Derivatives and Hedging,” which establishes accounting and disclosure requirements for derivative instruments and requires them to be measured at fair value and recorded as assets or liabilities in the consolidated balance sheets (see Note 5 for information on fair value). | |
Under ASC 815, hedge accounting is used to defer recognition of unrealized changes in the fair value of such financial instruments, for those contracts which qualify as fair value or cash flow hedges, as defined in the guidance. Historically, we have not designated any of our derivative contracts as fair value or cash flow hedges. Accordingly, the unrealized changes in fair value of the contracts are included in earnings in the period of the change as “Unrealized gain (loss) — oil and natural gas derivative contracts” for oil and natural gas contracts, and in interest expense for interest derivative contracts. Realized gains and losses are recorded in income in the period of settlement, and included in the related revenue account or in interest expense. Cash flows from settlements of derivative contracts are classified with the income or expense item to which such settlements directly relate. | |
Income Taxes | ' |
Income Taxes. The Company has elected under the Internal Revenue Code provisions to be treated as individual partnerships for tax purposes. Accordingly, items of income, expense, gains and losses flow through to the partners and are taxed at the partner level. Accordingly, no tax provision for federal income taxes is included in the consolidated financial statements. | |
The Company is subject to the Texas margin tax, which is considered a state income tax, and is included in “Benefit from (provision for) state income tax” on the consolidated statements of operations. The Company records state income tax (current and deferred) based on taxable income, as defined under the rules for the margin tax. | |
We follow guidance issued by the FASB in accounting for uncertainty in income taxes. This guidance clarifies the accounting for income taxes by prescribing the minimum recognition threshold an income tax position is required to meet before being recognized in the consolidated financial statements and applies to all income tax positions. Each income tax position is assessed using a two step process. A determination is first made as to whether it is more likely than not that the income tax position will be sustained, based upon technical merits, upon examination by the taxing authorities. If the income tax position is expected to meet the more likely than not criteria, the benefit recorded in the consolidated financial statements equals the largest amount that is greater than 50% likely to be realized upon its ultimate settlement. | |
We have considered our exposure under the standard at both the federal and state tax levels. We have not recorded any liabilities for uncertain tax positions as of December 31, 2013 and 2012. We record income tax, related interest, and penalties, if any, as a component of income tax expense. We did not incur any interest or penalties on income taxes for the years ended December 31, 2013, 2012, or 2011. | |
The Company’s tax returns for the years ended December 31, 2009 forward remain open for examination. None of the Company’s federal or state tax returns are currently under examination by the relevant authorities. | |
Revenue Recognition | ' |
Revenue Recognition. We recognize oil, natural gas and natural gas liquids revenues when products are delivered at a fixed or determinable price, title has transferred and collectability is reasonably assured. We use the sales method of accounting for recognition of natural gas imbalances. Revenue from drilling rigs has been recorded when services were performed. | |
Fair Value Of Financial Instruments | ' |
Fair Value of Financial Instruments. The fair value of cash, accounts receivable and current liabilities approximate book value due to their short-term nature. The estimate of fair value of long-term debt under our credit facility is not considered to be materially different from carrying value due to market rates of interest. The fair value of the debt to our founder is not practicable to determine. We have estimated the fair value of our $450 million senior notes payable at $482.6 million on December 31, 2013. Derivative financial instruments are carried at fair value. See Note 5 for further information on fair values of financial instruments. See Note 9 for information on long-term debt. | |
Acquisitions | ' |
Acquisitions. Acquisitions are accounted for as purchases using the acquisition method of accounting. Accordingly, the results of operations are included in our consolidated statements of operations from the closing date of the acquisitions. Purchase prices are allocated to acquired assets and assumed liabilities based on their estimated fair value at the time of the acquisition. | |
Recent Accounting Pronouncements | ' |
Recent Accounting Pronouncements | |
In January 2013 we adopted ASU No. 2011-11, which increases disclosures about offsetting assets and liabilities. New disclosures are required to enable users of financial statements to understand significant quantitative differences in balance sheets prepared under GAAP and International Financial Reporting Standards (IFRS) related to the offsetting of financial instruments. The additional disclosures are included in Note 6. | |
In February 2013, the FASB issued ASU No. 2013-04. The guidance requires an entity that is joint and severally liable to measure the obligation as the sum of the amount the entity has agreed with co-obligors to pay and any additional amount it expects to pay on behalf of one or more co-obligors. Required disclosures include a description of the nature of the arrangement, how the liability arose, the relationship with co-obligors and the terms and conditions of the arrangement. ASU No. 2013-04 is effective for annual and interim reporting periods beginning after December 15, 2013. We do not expect the adoption of this pronouncement to have a material impact on our consolidated financial statements. | |

Commodity Contract [Member] | ' |
Derivatives, Use of Derivatives | 'We account for our derivative contracts under the provisions of ASC 815, "Derivatives and Hedging." We have entered into forward-swap contracts and collar contracts to reduce our exposure to price risk in the spot market for oil and natural gas. We also utilize financial basis swap contracts, which address the price differential between market-wide benchmark prices and other benchmark pricing referenced in certain of our crude oil and natural gas sales contracts. Substantially all of our hedging agreements are executed by affiliates of the lenders under our credit facility described in Note 9 below, and are collateralized by the security interests of the respective affiliated lenders in certain of our assets under the credit facility. The contracts settle monthly and are scheduled to coincide with either oil production equivalent to barrels (Bbl) per month or gas production equivalent to volumes in millions of British thermal units (MMBtu) per month. The contracts represent agreements between us and the counter-parties to exchange cash based on a designated price, or in the case of financial basis hedging contracts, based on a designated price differential between various benchmark prices. Cash settlement occurs monthly based on the specified price benchmark. |

Derivative contracts are subject to master netting arrangements and are presented on a net basis in the consolidated balance sheets. This netting can cause derivative assets to be ultimately presented in a (liability) account on the consolidated balance sheets. Likewise, derivative (liabilities) could be presented in an asset account. | |

Derivative Financial Instruments [Abstract] | ' |
Derivative Asset, Setoff Rights, Description | 'Although our counterparties provide no collateral, the master derivative agreements with each counterparty effectively allow the Company, so long as it is not a defaulting party, after a default or the occurrence of a termination event, to set-off an unpaid hedging agreement receivable against the interest of the counterparty in any outstanding balance under the credit facility. If a counterparty were to default in payment of an obligation under the master derivative agreements, we could be exposed to commodity price fluctuations, and the protection intended by the hedge could be lost. The value of our derivative financial instruments would be impacted. |
