Accounting Policies [Abstract] | |
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Stone Energy Corporation (“Stone”) is an independent oil and natural gas company engaged in the acquisition, exploration, exploitation, development and operation of oil and gas properties. We began operating in the Gulf of Mexico (the “GOM”) Basin in 1993 and have established a technical and operational expertise in this area. We have leveraged our experience in the GOM conventional shelf and expanded our reserve base into the more prolific basins of the GOM deep water, Gulf Coast deep gas and the Marcellus and Utica shales in Appalachia. We were incorporated in 1993 as a Delaware corporation. Our corporate headquarters are located at 625 E. Kaliste Saloom Road, Lafayette, Louisiana 70508. We have additional offices in New Orleans, Louisiana, Houston, Texas and Morgantown, West Virginia. A summary of significant accounting policies followed in the preparation of the accompanying consolidated financial statements is set forth below. Basis of Presentation: The financial statements include our accounts and the accounts of our wholly owned subsidiaries, Stone Energy Offshore, L.L.C. (“Stone Offshore”), Stone Energy Holding, L.L.C., Stone Energy Canada, U.L.C., SEO A LLC and SEO B LLC. All intercompany balances have been eliminated. Certain prior year amounts have been reclassified to conform to current year presentation (see Note 11 - Long-Term Debt ). Use of Estimates: The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates are used primarily when accounting for depreciation, depletion and amortization (“DD&A”) expense, unevaluated property costs, estimated future net cash flows from proved reserves, costs to abandon oil and gas properties, income taxes, accruals of capitalized costs, operating costs and production revenue, capitalized general and administrative costs and interest, insurance recoveries, effectiveness and estimated fair value of derivative contracts, estimates of fair value in business combinations and contingencies. Fair Value Measurements: U.S. GAAP establishes a framework for measuring fair value and requires certain disclosures about fair value measurements. As of December 31, 2015 and 2014 , we held certain financial assets and liabilities that are required to be measured at fair value on a recurring basis, including our commodity derivative instruments and our investments in marketable securities. Hybrid Debt Instruments: In 2012, we issued $300,000 in aggregate principal amount of 1 3 ⁄ 4 % Senior Convertible Notes due 2017 (the “2017 Convertible Notes”). See Note 11 – Long-Term Debt . On that same day we entered into convertible note hedging transactions which are expected to reduce the potential dilution to our common shareholders upon conversion of the notes. In accordance with Accounting Standards Codification (“ASC”) 480-20 and ASC 470, we accounted for the debt and equity portions of the notes in a manner that will reflect our nonconvertible borrowing rate when interest is recognized in subsequent periods. This results in the separation of the debt component, classification of the remaining component in stockholders’ equity, and accretion of the resulting discount as interest expense. Additionally, the hedging transactions meet the criteria for classification as equity transactions and were recorded as such. Cash and Cash Equivalents: We consider all money market funds and highly liquid investments in overnight securities through our commercial bank accounts, which result in available funds on the next business day, to be cash and cash equivalents. Oil and Gas Properties: We follow the full cost method of accounting for oil and gas properties. Under this method, all acquisition, exploration, development and estimated abandonment costs, including certain related employee and general and administrative costs (less any reimbursements for such costs) and interest incurred for the purpose of finding oil and gas are capitalized. Such amounts include the cost of drilling and equipping productive wells, dry hole costs, lease acquisition costs, delay rentals and other costs related to such activities. Employee, general and administrative costs that are capitalized include salaries and all related fringe benefits paid to employees directly engaged in the acquisition, exploration and development of oil and gas properties, as well as all other directly identifiable general and administrative costs associated with such activities, such as rentals, utilities and insurance. We capitalize a portion of the interest costs incurred on our debt based upon the balance of our unevaluated property costs and our weighted-average borrowing rate. Employee, general and administrative costs associated with production operations and general corporate activities are expensed in the period incurred. Additionally, workover and maintenance costs incurred solely to maintain or increase levels of production from an existing completion interval are charged to lease operating expense in the period incurred. U.S. GAAP allows the option of two acceptable methods for accounting for oil and gas properties. The successful efforts method is the allowable alternative to the full cost method. The primary differences between the two methods are in the treatment of exploration costs, the computation of DD&A expense and the assessment of impairment of oil and gas properties. Under the full cost method, all exploratory costs are capitalized, while under the successful efforts method, exploratory costs associated with unsuccessful exploratory wells and all geological and geophysical costs are expensed. Under the full cost method, DD&A expense is computed on cost centers represented by entire countries, while under the successful efforts method, cost centers are represented by properties, or some reasonable aggregation of properties with common geological structural features or stratigraphic condition, such as fields or reservoirs. Under the full cost method, oil and gas properties are subject to the ceiling test as discussed below while under the successful efforts method oil and gas properties are assessed for impairment in accordance with ASC 360. We amortize our investment in oil and gas properties through DD&A expense using the units of production (the “UOP”) method. Under the UOP method, the quarterly provision for DD&A expense is computed by dividing production volumes for the period by the total proved reserves as of the beginning of the period (beginning of period reserves being determined by adding production to the end of period reserves), and applying the respective rate to the net cost of proved oil and gas properties, including future development costs. Under the full cost method, we compare, at the end of each financial reporting period, the present value of estimated future net cash flows from proved reserves (adjusted for hedges and excluding cash flows related to estimated abandonment costs) to the net capitalized costs of proved oil and gas properties, net of related deferred taxes. We refer to this comparison as a ceiling test. If the net capitalized costs of proved oil and gas properties exceed the estimated discounted future net cash flows from proved reserves, we are required to write down the value of our oil and gas properties to the value of the discounted cash flows. Sales of oil and gas properties are accounted for as adjustments to net oil and gas properties with no gain or loss recognized, unless the adjustment would significantly alter the relationship between capitalized costs and proved reserves. Asset Retirement Obligations: U.S. GAAP requires us to record our estimate of the fair value of liabilities related to future asset retirement obligations in the period the obligation is incurred. Asset retirement obligations relate to the removal of facilities and tangible equipment at the end of an oil and gas property’s useful life. The application of this rule requires the use of management’s estimates with respect to future abandonment costs, inflation, market risk premiums, useful life and cost of capital. U.S. GAAP requires that our estimate of our asset retirement obligations does not give consideration to the value the related assets could have to other parties. Other Property and Equipment: Our office buildings in Lafayette, Louisiana are being depreciated on the straight-line method over their estimated useful lives of 39 years. Inventory: We maintain an inventory of tubular goods. Items remain in inventory until dedicated to specific projects, at which time they are transferred to oil and gas properties. Items are carried at the lower of cost or market based on the specific identification method. Earnings Per Common Share: Under U.S. GAAP, certain instruments granted in share-based payment transactions are considered participating securities prior to vesting and are therefore required to be included in the earnings allocation in calculating earnings per share under the two-class method. Companies are required to treat unvested share-based payment awards with a right to receive non-forfeitable dividends as a separate class of securities in calculating earnings per share. Production Revenue: We recognize production revenue under the entitlements method of accounting. Under this method, revenue is deferred for deliveries in excess of our net revenue interest, while revenue is accrued for undelivered or underdelivered volumes. Production imbalances are generally recorded at the estimated sales price in effect at the time of production. Income Taxes: Provisions for income taxes include deferred taxes resulting primarily from temporary differences due to different reporting methods for oil and gas properties for financial reporting and income tax purposes. For financial reporting purposes, all exploratory and development expenditures related to evaluated projects, including future abandonment costs, are capitalized and amortized using the UOP method. For income tax purposes, only the leasehold, geological and geophysical and equipment relative to successful wells are capitalized and recovered through DD&A, although for 2013 , 2014 and 2015 , special provisions allowed for current deductions for the cost of certain equipment. Generally, most other exploratory and development costs are charged to expense as incurred; however, we follow certain provisions of the Internal Revenue Code that allow capitalization of intangible drilling costs where management deems appropriate. Other financial and income tax reporting differences occur as a result of statutory depletion, different reporting methods for sales of oil and gas reserves in place, different reporting methods used in the capitalization of employee, general and administrative and interest expense, and different reporting methods for employee compensation. Derivative Instruments and Hedging Activities: The nature of a derivative instrument must be evaluated to determine if it qualifies as a hedging instrument. If the instrument qualifies as a hedging instrument, it is recorded as either an asset or liability measured at fair value and subsequent changes in the derivative’s fair value are recognized in stockholders’ equity through other comprehensive income (loss), net of related taxes, to the extent the hedge is considered effective. Monthly settlements of effective hedges are reflected in revenue from oil and natural gas production and cash flows from operating activities. Instruments not qualifying as hedging instruments are recorded in our balance sheet at fair value and subsequent changes in fair value are recognized in earnings through derivative expense (income). Monthly settlements of ineffective hedges and derivative instruments not qualifying as hedging instruments are recognized in earnings through derivative expense (income) and cash flows from operating activities. Share-Based Compensation: We record share-based compensation using the grant date fair value of issued stock options and restricted stock over the vesting period of the instrument. We utilize the Black-Scholes option pricing model to measure the fair value of stock options. The fair value of restricted shares is typically determined based on the average of our high and low stock prices on the grant date. |

GOING CONCERN | GOING CONCERN: The accompanying consolidated financial statements have been prepared assuming the company will continue as a going concern, which contemplates continuity of operations, realization of assets and the satisfaction of liabilities in the normal course of business for the twelve month period following the date of these consolidated financial statements. As such, the accompanying consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amount and classification of liabilities that may result should the company be unable to continue as a going concern. The level of our indebtedness of $1,137,000 and the current commodity price environment have presented challenges as they relate to our ability to comply with the covenants in the agreements governing our indebtedness. At December 31, 2015, we were in compliance with all of our financial covenants under our bank credit facility and the indentures governing our outstanding notes. However, given the lower commodity prices and our reduced hedged position in 2016, we anticipate that we could exceed the Consolidated Funded Debt to consolidated EBITDA financial ratio covenant of 3.75 to 1 set forth in our bank credit agreement at the end of the first quarter of 2016, which would require us to seek a waiver or amendment from our bank lenders. If we are unable to reach an agreement with our banks or find acceptable alternative financing, it may lead to an event of default under our bank credit facility. If following an event of default, the banks were to accelerate repayment under the bank credit facility, it may result in an event of default and an acceleration under our other debt instruments. These conditions raise substantial doubt about our ability to continue as a going concern. We are currently in discussions with our banks regarding an amendment to our bank credit facility to address this potential covenant issue. We cannot provide any assurances that we will reach an agreement with the lenders under our bank credit facility on a waiver or amendment on a timely basis, or on satisfactory terms, to alleviate any non-compliance with our debt covenants. Additionally, we have $1,075,000 of senior indebtedness that we need to restructure or pay down. We are in the process of analyzing various strategic alternatives to address our liquidity and capital structure, including strategic and refinancing alternatives through a private restructuring, asset sales and a prepackaged bankruptcy filing. We cannot provide any assurances that we will be able to complete a private restructuring or asset sales on satisfactory terms to provide the liquidity to restructure or pay down our senior indebtedness. |

Stock options that were considered antidilutive because the exercise price of the options exceeded the average price of our common stock for the applicable period totaled approximately 242,000 shares during the year ended December 31, 2013 . During the years ended December 31, 2015 , 2014 and 2013 , approximately 418,000 , 384,000 and 358,000 shares of our common stock, respectively, were issued from authorized shares upon the lapsing of forfeiture restrictions of restricted stock and the exercise of stock options by employees and nonemployee directors. In May 2014, 5,750,000 shares of our common stock were issued in a public offering. For the years ended December 31, 2015 and 2014, the 2017 Convertible Notes had no dilutive effect in the diluted earnings per share computation as we had a net loss for such years. For the year ended December 31, 2013 , the average price of our common stock was less than the effective conversion price for such notes, resulting in no dilutive effect in the diluted earnings per share computation under the treasury stock method. For the years ended December 31, 2015 , 2014 and 2013 , the average price of our common stock was less than the strike price of the Sold Warrants (as defined in Note 11 – Long-Term Debt ) and therefore, such warrants were not dilutive for such years. Based on the terms of the Purchased Call Options (as defined in Note 11 – Long-Term Debt ), such call options are antidilutive and therefore, were not included in the calculation of diluted earnings per share. |

CONCENTRATIONS | CONCENTRATIONS: Sales to Major Customers Our production is sold on month-to-month contracts at prevailing prices. We obtain credit protections, such as parental guarantees, from certain of our purchasers. The following table identifies customers from whom we derived 10% or more of our total oil and natural gas revenue during the indicated periods: Year Ended December 31, 2015 2014 2013 Phillips 66 Company 53 % 31 % 35 % Shell Trading (US) Company 13 % 32 % 33 % The maximum amount of credit risk exposure at December 31, 2015 relating to these customers was $20,826 . We believe that the loss of any of these purchasers would not result in a material adverse effect on our ability to market future oil and natural gas production. Production and Reserve Volumes- Unaudited Approximately 99% of our estimated proved reserves at December 31, 2015 and 56% of our production during 2015 were associated with our GOM deep water, conventional shelf and deep gas properties. Approximately 1% of our estimated proved reserves at December 31, 2015 and 44% of our production during 2015 were associated with our Appalachian properties. Cash and Cash Equivalents A substantial portion of our cash balances are not federally insured. |

DIVESTITURES | DIVESTITURES: On January 16, 2014, we completed the sale of our interests in the Cut Off and Clovelly fields (onshore Louisiana) for cash consideration at closing of approximately $44,804 and the assumption of the associated asset retirement obligations of approximately $9,162 . On July 31, 2014, we completed the sale of certain non-core properties in the GOM conventional shelf for cash consideration at closing of approximately $177,647 , after giving effect to preliminary purchase price adjustments and the assumption of the associated asset retirement obligations of approximately $125,198 . Additionally, in 2014, we completed the sales of our interests in other non-core fields, including Katie (Pennsylvania), Hatch Point (Utah), Falls City (Texas) and South Marsh Island Block 192 (GOM), for a combined cash consideration of approximately $26,065 and the assumption of the associated asset retirement obligations of approximately $3,440 . These sales were accounted for as reductions to net proved oil and gas properties, with total cash consideration and the assumed asset retirement obligation recorded as an increase to accumulated DD&A. No gain or loss was recognized since the adjustments did not significantly alter the relationship between capitalized costs and proved reserves. All of the proceeds from the July 31, 2014 sale of certain of our non-core GOM conventional shelf properties were deposited with a Qualified Intermediary (under the terms of a Qualified Trust Agreement and Exchange Agreement) for potential reinvestment in like-kind replacement property as defined under Section 1031 of the Internal Revenue Code, and were included in our balance sheet as restricted cash at December 31, 2014. Compliance with provisions under the Qualified Trust Agreement and Exchange Agreement provided for deferral of taxable gain on these sales proceeds. We identified qualified replacement properties and had until January 27, 2015 to close on such properties in order to achieve deferral of our taxable gain. We did not close on such a transaction by January 27, 2015, and the funds were released from restrictions and reclassified to cash and cash equivalents at such date. |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES | DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES: Our hedging strategy is designed to protect our near and intermediate term cash flows from future declines in oil and natural gas prices. This protection is essential to capital budget planning, which is sensitive to expenditures that must be committed to in advance, such as rig contracts and the purchase of tubular goods. We enter into derivative transactions to secure a commodity price for a portion of our expected future production that is acceptable at the time of the transaction. These derivatives are generally designated as cash flow hedges upon entering into the contracts. We do not enter into derivative transactions for trading purposes. We have no fair value hedges. We have entered into fixed-price swaps and costless collars with various counterparties for a portion of our expected 2016 oil and natural gas production from the Gulf Coast Basin. Our fixed-price oil swap settlements and oil collar settlements are based on an average of the New York Mercantile Exchange (“NYMEX”) closing price for West Texas Intermediate crude oil during the entire calendar month. Our fixed-price gas swap settlements are based on the NYMEX price for the last day of a respective contract month. Swaps typically provide for monthly payments by us if prices rise above the swap price or monthly payments to us if prices fall below the swap price. Collar contracts typically require payments by us if the NYMEX average closing price is above the ceiling price or payments to us if the NYMEX average closing price is below the floor price. Our fixed-price swap contracts are with The Toronto-Dominion Bank, The Bank of Nova Scotia and Natixis. Our oil collar contract is with The Bank of Nova Scotia. All of our derivative transactions have been carried out in the over-the-counter market and are not typically subject to margin-deposit requirements. The use of derivative instruments involves the risk that the counterparties will be unable to meet the financial terms of such transactions. The counterparties to all of our derivative instruments have an "investment grade" credit rating. We monitor the credit ratings of our derivative counterparties on an ongoing basis. Although we have entered into derivative contracts with multiple counterparties to mitigate our exposure to any individual counterparty, if any of our counterparties were to default on its obligations to us under the derivative contracts or seek bankruptcy protection, we may not realize the benefit of some of our derivative instruments and incur a loss. At December 31, 2015, two counterparties accounted for approximately 86% of our contracted volumes. All of our derivative instruments are with lenders under our bank credit facility. The following tables illustrate our derivative positions for calendar year 2016 as of February 22, 2016 : Fixed-Price Swaps (NYMEX) Natural Gas Oil Daily Volume (MMBtus/d) Swap Price ($/MMBtu) Daily Volume (Bbls/d) Swap Price ($/Bbl) 2016 10,000 4.110 1,000 49.75 2016 10,000 4.120 1,000 52.78 2016 1,000 90.00 Costless Collar (NYMEX) Oil Daily Volume (Bbls/d) Floor Price ($) Ceiling Price ($) 2016 1,000 45.00 54.75 All of our derivative instruments at December 31, 2013 were designated as effective cash flow hedges. During 2014, certain of our natural gas derivative instruments no longer qualified as cash flow hedges, as it was no longer probable, subsequent to the sale of our non-core GOM conventional shelf properties (see Note 6 – Divestitures ), that GOM natural gas production would be sufficient to cover the GOM volumes hedged. Accordingly, we discontinued hedge accounting for certain contracts for the months of August through December 2014 and January through December 2015. Additionally, a small portion of our cash flow hedges are typically determined to be ineffective because oil and natural gas price changes in the markets in which we sell our products are not 100% correlative to changes in the underlying price basis indicative in the derivative contract. At December 31, 2015 , we had accumulated other comprehensive income of $24,025 , net of tax, related to the fair value of our effective cash flow hedges that were outstanding as of December 31, 2015 .The $24,025 of accumulated other comprehensive income will be reclassified into earnings in the next 12 months.

It is our policy to not offset our derivative contracts in presenting the fair value of these contracts as assets and liabilities in our balance sheet. As of December 31, 2015 and 2014, all of our derivative contracts were in an asset position and therefore, there was no potential impact of the rights of offset. |
FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract] | |
FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS: U.S. GAAP establishes a fair value hierarchy that has three levels based on the reliability of the inputs used to determine the fair value. These levels include: Level 1, defined as inputs such as unadjusted quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for use when little or no market data exists, therefore requiring an entity to develop its own assumptions. As of December 31, 2015 and 2014 , we held certain financial assets and liabilities that are required to be measured at fair value on a recurring basis, including our commodity derivative instruments and our investments in marketable securities. We utilize the services of an independent third party to assist us in valuing our derivative instruments. We used the income approach in determining the fair value of our derivative instruments utilizing a proprietary pricing model. The model accounts for our credit risk and the credit risk of our counterparties in the discount rate applied to estimated future cash inflows and outflows. Our swap contracts are included within the Level 2 fair value hierarchy, and our collar contracts are included within the Level 3 fair value hierarchy. Significant unobservable inputs used in establishing fair value for the collars were the volatility impacts in the pricing model as it relates to the call portion of the collar. For a more detailed description of our derivative instruments, see Note 7 – Derivative Instruments and Hedging Activities . We used the market approach in determining the fair value of our investments in marketable securities, which are included within the Level 1 fair value hierarchy. We had no liabilities measured at fair value on a recurring basis at December 31, 2015 and 2014. The following tables present our assets that are measured at fair value on a recurring basis at December 31, 2015 and 2014: Fair Value Measurements at December 31, 2015 Assets Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Marketable securities (Other assets) $ 8,499 $ 8,499 $ — $ — Derivative contracts 38,576 — 36,603 1,973 Total $ 47,075 $ 8,499 $ 36,603 $ 1,973 Fair Value Measurements at December 31, 2014 Assets Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Marketable securities (Other assets) $ 8,425 $ 8,425 $ — $ — Derivative contracts 153,512 — 153,512 — Total $ 161,937 $ 8,425 $ 153,512 $ — The table below presents a reconciliation for assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the year ended December 31, 2015 .

As of December 31, 2015 and 2014 , the fair value of the liability component of the 2017 Convertible Notes was approximately $217,117 and $252,587 , respectively. As of December 31, 2015 and 2014 , the fair value of the 7 1 ⁄ 2 % Senior Notes due 2022 (the “2022 Notes”) was approximately $271,250 and $664,563 , respectively. The fair value of the 2022 Notes was determined based on quotes obtained from brokers, which represent Level 1 inputs. We applied fair value concepts in determining the liability component of the 2017 Convertible Notes (see Note 11 – Long-Term Debt ) at inception and at December 31, 2015 and 2014 . The fair value of the liability was estimated using an income approach. The significant inputs in these determinations were market interest rates based on quotes obtained from brokers and represent Level 2 inputs. |

INCOME TAXES | INCOME TAXES: An analysis of our deferred taxes follows: As of December 31, 2015 2014 Tax effect of temporary differences: Net operating loss carryforwards $ 31,624 $ 99,615 Oil and gas properties – full cost 76,766 (476,367 ) Asset retirement obligations 79,618 113,907 Stock compensation 5,199 5,603 Hedges (13,598 ) (54,439 ) Accrued incentive compensation 1,234 6,185 Other (722 ) (966 ) Total deferred tax assets (liabilities) 180,121 (306,462 ) Valuation allowance (180,121 ) — Net deferred tax liabilities $ — $ (306,462 ) We estimate that we had ($44,096) , $159 and ($10,904) of current federal income tax expense (benefit) for the years ended December 31, 2015, 2014 and 2013, respectively. For the years ended December 31, 2015, 2014 and 2013, we recorded deferred income tax expense (benefits) of ($272,311) , ($102,177) and $79,629 , respectively. The deferred income tax benefits were a result of our losses before income taxes attributable primarily to ceiling test write-downs of our oil and gas properties (see Note 17 - Supplemental Information on Oil and Natural Gas Operations - Unaudited ). We had current income tax receivables of $46,174 and $7,212 at December 31, 2015 and 2014 , respectively, both of which were expected tax refunds from the carryback of net operating losses to previous tax years. For tax reporting purposes, net operating loss carryforwards totaled approximately $97,225 at December 31, 2015 . If not utilized, the majority of such carryforwards would expire in 2035 . In addition, we had approximately $1,056 in statutory depletion deductions available for tax reporting purposes that may be carried forward indefinitely. Recognition of a deferred tax asset associated with these and other carryforwards is dependent upon our evaluation that it is more likely than not that the asset will ultimately be realized. As a result of the significant declines in commodity prices and the resulting ceiling test write-downs and net losses incurred over the past several quarters, we determined during 2015 that it was more likely than not that a portion of our deferred tax assets will not be realized in the future. Accordingly, we established a $180,121 valuation allowance against a portion of our deferred tax assets. Our assessment of the realizability of our deferred tax assets is based on the weight of all available evidence, both positive and negative, including future reversals of deferred tax liabilities. A reconciliation between the statutory federal income tax rate and our effective income tax rate as a percentage of income before income taxes follows: Year Ended December 31, 2015 2014 2013 Income tax expense computed at the statutory federal income tax rate 35.0% 35.0% 35.0% State taxes 0.6 1.0 1.0 Change in valuation allowance (12.8) — — IRC Sec. 162(m) limitation (0.1) (0.5) 0.8 Tax deficits on stock compensation (0.1) (0.2) — Other (0.1) (0.3) 0.1 Effective income tax rate 22.5% 35.0% 36.9% Income taxes allocated to accumulated other comprehensive income related to oil and gas hedges amounted to ($35,737) , $49,601 and ($17,003) for the years ended December 31, 2015 , 2014 and 2013 , respectively. As of December 31, 2015 , we had unrecognized tax benefits of $491 . If recognized, all of our unrecognized tax benefits would impact our effective tax rate. A reconciliation of the total amounts of unrecognized tax benefits follows: Total unrecognized tax benefits as of December 31, 2014 $ — Increases (decreases) in unrecognized tax benefits as a result of: Tax positions taken during a prior period 491 Tax positions taken during the current period — Settlements with taxing authorities — Lapse of applicable statute of limitations — Total unrecognized tax benefits as of December 31, 2015 $ 491 Our unrecognized tax benefits pertain to a proposed state income tax audit adjustment. We believe that our unrecognized tax benefits may be reduced to zero within the next 12 months upon completion and ultimate settlement of the examination. It is our policy to classify interest and penalties associated with underpayment of income taxes as interest expense and general and administrative expenses, respectively. We recognized $131 of interest expense and no penalties related to uncertain tax positions for the year ended December 31, 2015 . No such amounts were recognized for the year ended December 31, 2014. The liabilities for unrecognized tax benefits and accrued interest payable are components of other current liabilities on our balance sheet. The tax years 2012 through 2015 remain subject to examination by major tax jurisdictions. |

Debt Disclosure [Abstract] | |
LONG-TERM DEBT | LONG-TERM DEBT: Long-term debt consisted of the following at: December 31, 2015 2014 1 3 ⁄ 4 % Senior Convertible Notes due 2017 $ 279,244 $ 262,791 7 1 ⁄ 2 % Senior Notes due 2022 770,009 769,490 Revolving credit facility — — 4.20% Building Loan 11,702 — Total long-term debt $ 1,060,955 $ 1,032,281 Revolving Credit Facility On June 24, 2014 , we entered into an amended and restated revolving credit facility with commitments totaling $900,000 (subject to borrowing base limitations) through a syndicated bank group, replacing our previous facility. The bank credit facility matures on July 1, 2019 . Our initial borrowing base under the bank credit facility was set at $500,000 and was reaffirmed at $500,000 in October 2015. As of December 31, 2015 , we had no outstanding borrowings under the bank credit facility and $19,221 in letters of credit had been issued pursuant to the bank credit facility, leaving $480,779 of availability under the bank credit facility. As of February 22, 2016 , we had $50,000 of outstanding borrowings under the bank credit facility and $19,221 in letters of credit had been issued pursuant to the bank credit facility, leaving $430,779 of availability under the bank credit facility. Subject to certain exceptions, the bank credit facility is required to be guaranteed by all of our material domestic direct and indirect subsidiaries. As of December 31, 2015, the bank credit facility was guaranteed by Stone Offshore, SEO A LLC and SEO B LLC (collectively, the "Guarantor Subsidiaries"). The borrowing base under the bank credit facility is redetermined semi-annually, typically in May and November, by the lenders, taking into consideration the estimated loan value of our oil and gas properties and those of our subsidiaries that guarantee the bank credit facility in accordance with the lenders’ customary practices for oil and gas loans. In addition, we and the lenders each have discretion at any time, but not more than two additional times in any calendar year, to have the borrowing base redetermined. If, due to a redetermination of our borrowing base, our outstanding bank credit facility borrowings plus any outstanding letters of credit exceed our redetermined borrowing base (referred to as a borrowing base deficiency), we could be required to repay such borrowing base deficiency. Our agreement with the banks allows us to cure a borrowing base deficiency through any combination of the following actions: (1) repay amounts outstanding sufficient to cure the deficiency within 10 days after our written election to do so; (2) add additional oil and gas properties acceptable to the banks to the borrowing base and take such actions necessary to grant the banks a mortgage in the properties within 30 days after our written election to do so; and/or (3) arrange to pay the deficiency in six equal monthly installments. The bank credit facility is collateralized by substantially all of the assets of Stone and its material subsidiaries. We are required to mortgage, and grant a security interest in, our oil and natural gas reserves representing at least 80% of the discounted present value of the future net cash flows from our proved oil and natural gas reserves reviewed in determining the borrowing base. Interest on loans under the bank credit facility is calculated using the London Interbank Offering (“LIBOR”) rate or the base rate, at the election of Stone. The margin for loans at the LIBOR rate is determined based on borrowing base utilization and ranges from 1.500% to 2.500% . Under the financial covenants of the bank credit facility, we must (1) maintain a ratio of Consolidated Funded Debt to consolidated EBITDA, as defined in the credit agreement, for the preceding four quarterly periods of not greater than 3.75 to 1 and (2) maintain a ratio of consolidated EBITDA to consolidated Net Interest Expense, as defined in the credit agreement, for the preceding four quarterly periods of not less than 2.5 to 1. As of December 31, 2015 , our Consolidated Funded Debt to consolidated EBITDA ratio was 3.09 to 1 and our consolidated EBITDA to consolidated Net Interest Expense ratio was approximately 7.91 to 1 . In addition, our bank credit facility includes certain customary restrictions or requirements with respect to disposition of properties, incurrence of additional debt, change of control and reporting responsibilities. These covenants may limit or prohibit us from paying cash dividends but do allow for limited stock repurchases. These covenants also restrict our ability to prepay other indebtedness under certain circumstances. We were in compliance with all covenants as of December 31, 2015 . Building Loan On November 20, 2015, we entered into an $11,802 term loan agreement (the "Building Loan"), maturing on December 20, 2030. The Building Loan bears interest at a rate of 4.20% per annum and is to be repaid in 180 equal monthly installments of $73 commencing on December 20, 2015. The Building Loan is collaterized by our two Lafayette, Louisiana office buildings. Under the financial covenants of the Building Loan, we must maintain a ratio of EBITDA to Net Interest Expense of not less than 2.00 to 1.00. As of December 31, 2015, our EBITDA to Net Interest Expense ratio was 7.91 to 1. In addition, the Building Loan contains certain customary restrictions or requirements with respect to change of control and reporting responsibilities. 2017 Convertible Notes On March 6, 2012, we issued in a private offering $300,000 in aggregate principal amount of the 2017 Convertible Notes to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The 2017 Convertible Notes are convertible into cash, shares of our common stock or a combination of cash and shares of our common stock, based on an initial conversion rate of 2.3445 shares of our common stock per $1 principal amount of 2017 Convertible Notes, which corresponds to an initial conversion price of approximately $42.65 per share of our common stock. On December 31, 2015 , our closing share price was $4.29 . The conversion rate, and thus the conversion price, may be adjusted under certain circumstances as described in the indenture related to the 2017 Convertible Notes. The 2017 Convertible Notes may be converted by the holder, in multiples of $ 1 principal amount, only under the following circumstances: • prior to December 1, 2016, on any date during any calendar quarter beginning after June 30, 2012 (and only during such calendar quarter) if the closing sale price of our common stock was more than 130% of the then current conversion price for at least 20 trading days in the period of the 30 consecutive trading days ending on the last trading day of the previous calendar quarter; • prior to December 1, 2016, if we distribute to all or substantially all holders of our common stock rights, options or warrants entitling them to purchase, for a period of 45 calendar days or less from the declaration date for such distribution, shares of our common stock at a price per share less than the average closing sale price of our common stock for the 10 consecutive trading days immediately preceding, but excluding, the declaration date for such distribution; • prior to December 1, 2016, if we distribute to all or substantially all holders of our common stock cash, other assets, securities or rights to purchase our securities, which distribution has a per share value exceeding 10% of the closing sale price of our common stock on the trading day immediately preceding the declaration date for such distribution, or if we engage in certain corporate transactions described in the indenture related to the 2017 Convertible Notes; • prior to December 1, 2016, during the five consecutive business-day period following any five consecutive trading-day period in which the trading price per $1 principal amount of 2017 Convertible Notes for each trading day during such five trading-day period was less than 98% of the closing sale price of our common stock for each trading day during such five trading-day period multiplied by the then current conversion rate; or • on or after December 1, 2016, and prior to the close of business on the second scheduled trading day immediately preceding the maturity date of the 2017 Convertible Notes, which is March 1, 2017, without regard to the foregoing conditions. Upon conversion, we will be obligated to pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock. If we satisfy our conversion obligation solely in cash or through payment and delivery, as the case may be, of a combination of cash and shares of our common stock, the amount of cash and shares of common stock, if any, due upon conversion will be based on a daily conversion value (as described in the indenture related to the 2017 Convertible Notes) calculated on a proportionate basis for each trading day in a 25 consecutive trading-day conversion period (as described in the indenture related to the 2017 Convertible Notes). Upon any conversion, subject to certain exceptions, holders of the 2017 Convertible Notes will not receive any cash payment representing accrued and unpaid interest. Instead, interest will be deemed to be paid by the cash, shares of our common stock or a combination of cash and shares of our common stock paid or delivered, as the case may be, upon conversion of a 2017 Convertible Note. The 2017 Convertible Notes will be due on March 1, 2017, unless earlier converted or repurchased by us at the option of the holder(s), and interest is payable on the 2017 Convertible Notes each March 1 and September 1. On the maturity date, each holder will be entitled to receive $1 in cash for each $1 in principal amount of 2017 Convertible Notes, together with any accrued and unpaid interest to, but excluding, the maturity date. In connection with the offering, we entered into convertible note hedge transactions with respect to our common stock (the “Purchased Call Options”) with Barclays Capital Inc., acting as agent for Barclays Bank PLC and Bank of America, N.A. (the “Dealers”). We paid an aggregate amount of approximately $70,830 to the Dealers for the Purchased Call Options. The Purchased Call Options cover, subject to customary antidilution adjustments, approximately 7,033,470 shares of our common stock at a strike price that corresponds to the initial conversion price of the 2017 Convertible Notes, also subject to adjustment, and are exercisable upon conversion of the 2017 Convertible Notes. We also entered into separate warrant transactions whereby, in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act, we sold to the Dealers warrants to acquire, subject to customary antidilution adjustments, approximately 7,033,470 shares of our common stock (the “Sold Warrants”) at a strike price of $55.91 per share of our common stock. We received aggregate proceeds of approximately $40,170 from the sale of the Sold Warrants to the Dealers. If, upon expiration of the Sold Warrants, the price per share of our common stock, as measured under the Sold Warrants, is greater than the strike price of the Sold Warrants, we will be required to issue, without further consideration, under each Sold Warrant a number of shares of our common stock with a value equal to the amount of such difference. As of December 31, 2015 , the carrying amount of the liability component of the 2017 Convertible Notes was $279,244 and $1,750 had been accrued in connection with the March 1, 2016 interest payment. During the year ended December 31, 2015 , we recognized $15,019 of interest expense for the amortization of the discount and $1,434 of interest expense for the amortization of deferred financing costs related to the 2017 Convertible Notes. During the year ended December 31, 2014 , we recognized $13,951 of interest expense for the amortization of the discount and $1,332 of interest expense for the amortization of deferred financing costs related to the 2017 Convertible Notes. During the year ended December 31, 2013 , we recognized $12,599 of interest expense for the amortization of the discount and $1,238 of interest expense for the amortization of deferred financing costs related to the 2017 Convertible Notes. During each of the years ended December 31, 2015 , 2014 and 2013 , we recognized $5,250 of interest expense related to the contractual interest coupon on the 2017 Convertible Notes. 2022 Notes On November 8, 2012, we completed the public offering of $300,000 aggregate principal amount of our 2022 Notes, which are fully and unconditionally guaranteed on a senior unsecured basis by Stone Offshore, SEO A LLC, SEO B LLC and by certain future restricted subsidiaries of Stone. The net proceeds from the offering after deducting underwriting discounts, commissions, fees and expenses totaled $293,203 . On November 27, 2013, we completed the public offering of an additional $475,000 aggregate principal amount of our 2022 Notes at a 3% premium. The net proceeds from this offering after deducting underwriting discounts, commissions, fees and expenses totaled $480,195 . The 2022 Notes rank equally in right of payment with all of our existing and future senior debt, and rank senior in right of payment to all of our existing and future subordinated debt. The 2022 Notes mature on November 15, 2022, and interest is payable on the 2022 Notes on each May 15 and November 15. We may redeem some or all of the 2022 Notes at any time on or after November 15, 2017 at the redemption prices specified in the indenture, and we may redeem some or all of the 2022 Notes prior to November 15, 2017 at a make-whole redemption price as specified in the indenture. If we sell certain assets and do not reinvest the proceeds or repay senior indebtedness, or we experience certain changes of control, each as described in the indenture, we must offer to repurchase the 2022 Notes. The 2022 Notes provide for certain covenants, which include, without limitation, restrictions on liens, indebtedness, asset sales, dividend payments and other restricted payments. The violation of any of these covenants could give rise to a default, which if not cured could give the holder of the 2022 Notes a right to accelerate payment. At December 31, 2015 , $7,266 had been accrued in connection with the May 15, 2016 interest payment. Deferred Financing Cost and Interest Cost In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03, " Interest - Imputation of Interest, Simplifying the Presentation of Debt Issuance Costs " which requires the presentation of debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability and not as a separate asset. In August 2015, the guidance was further clarified to state that debt issuance costs related to line-of-credit arrangements could be reported as a deferred asset and subsequently amortized ratably over the term of the line-of-credit agreement. We have elected to early adopt this standard effective December 31, 2015. As a result of our early adoption of ASU 2015-03, deferred financing costs, net of accumulated amortization, related to the 2017 Convertible Notes, 2022 Notes and Building Loan were reclassified from other assets to a direct deduction from the carrying amount of the debt liabilities. At December 31, 2015 and 2014 , approximately $6,869 and $8,754 , respectively, of unamortized deferred financing costs were deducted from the carrying amount of the related debt liabilities for the 2017 Convertible Notes, 2022 Notes and Building Loan. The deferred financing costs, net of accumulated amortization, of $2,845 and $3,661 at December 31, 2015 and 2014, respectively, related to the bank credit facility remain classified as other assets. The costs associated with the 2017 Convertible Notes are being amortized over the life of the notes using a method that applies an effective interest rate of 7.51% . The costs associated with the November 2012 issuance and November 2013 issuance of the 2022 Notes are being amortized over the life of the notes using a method that applies effective interest rates of 7.75% and 7.04% , respectively. The costs associated with the Building Loan are being amortized using the effective interest method over the term of the Building Loan. The costs associated with the bank credit facility are being amortized on a straight-line basis over the term of the facility. Total interest cost incurred, before capitalization, on all obligations for the years ended December 31, 2015 , 2014 and 2013 was $85,267 , $84,577 and $79,697 respectively. |

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
SHARE-BASED COMPENSATION | SHARE-BASED COMPENSATION: We currently maintain the Stone Energy Corporation 2009 Amended and Restated Stock Incentive Plan, as amended from time to time (the “2009 Plan”). The 2009 Plan was originally approved at the 2009 Annual Meeting of Stockholders and is an amendment and restatement of the company’s 2004 Amended and Restated Stock Incentive Plan (the “2004 Plan”), and it supersedes and replaces in its entirety the 2004 Plan. The 2009 Plan provides for the granting of (a) “incentive” stock options as defined in Section 422 of the Code, (b) stock options that do not constitute incentive stock options (“non-statutory” stock options), (c) stock appreciation rights in conjunction with an incentive or non-statutory stock option, (d) restricted stock, (e) restricted stock units, (f) dividend equivalents, (g) other stock-based awards, (h) conversion awards, and (i) cash awards, any of which may be further designated as performance awards (collectively referred to as “awards”). See Note 16 - Employee Benefit Plans-Stock Incentive Plans for more information. No stock options have been granted pursuant to the 2009 Plan since its initial effective date on May 28, 2009; however, we have previously granted options under the 2004 Plan that remain outstanding. Stock options previously granted to employees vested ratably over a five -year service-vesting period and expire 10 years subsequent to award. Stock options issued to non-employee directors vested ratably over a three -year service-vesting period and expire 10 years subsequent to award. We have granted restricted stock awards under the 2009 Plan, which awards typically vest over a one -year or three -year period. We record share-based compensation expense under U.S. GAAP for share-based compensation awards based on the fair value on the date of grant. Compensation expense for share-based compensation awards is recognized in our financial statements over the vesting period of the award. For the year ended December 31, 2015 , we incurred $17,917 of share-based compensation, all of which related to restricted stock issuances, and of which a total of approximately $5,593 was capitalized into oil and gas properties. For the year ended December 31, 2014 , we incurred $17,051 of share-based compensation, all of which related to restricted stock issuances, and of which a total of approximately $5,797 was capitalized into oil and gas properties. For the year ended December 31, 2013 , we incurred $15,425 of share-based compensation, of which $15,405 related to restricted stock issuances and $20 related to stock option grants, and of which a total of approximately $5,078 was capitalized into oil and gas properties. Because of the non-cash nature of share-based compensation, the expensed portion of share-based compensation is added back to net income in arriving at net cash provided by operating activities in our statement of cash flows. The capitalized portion is not included in net cash used in investing activities. Stock Options. There were no stock option grants during the years ended December 31, 2015 , 2014 or 2013 .

The fair value of restricted shares is typically determined based on the average of our high and low stock prices on the grant date. During the year ended December 31, 2015 , we issued 1,420,475 shares of restricted stock valued at $23,722 . During the year ended December 31, 2014 , we issued 674,904 shares of restricted stock valued at $24,593 . During the year ended December 31, 2013 , we issued 848,498 shares of restricted stock valued at $17,487 . A summary of the restricted stock activity under the 2009 Plan for the years ended December 31, 2015 , 2014 and 2013 is as follows (amounts in table represent actual values): 2015 2014 2013 Number of Restricted Shares Wgtd.

That cost is being amortized on a straight-line basis over the vesting period and is expected to be recognized over a weighted-average period of 1.7 years . Under U.S. GAAP, if tax deductions exceed book compensation expense, then excess tax benefits are credited to additional paid-in capital to the extent realized. If book compensation expense exceeds tax deductions, the tax deficit results in either a reduction in additional paid-in capital and/or an increase in income tax expense, depending on the pool of available excess tax benefits to offset such deficit. Adjustments to additional paid-in capital related to the net tax effect of stock option exercises and restricted stock vesting were $0 , ($54) and ($884) in 2015 , 2014 and 2013 , respectively. Additionally, during 2015 and 2014 , $1,314 and $609 of tax deficits were charged to income tax expense, respectively. |

Equity [Abstract] | |
SHARE REPURCHASE PROGRAM | SHARE REPURCHASE PROGRAM: On September 24, 2007, our board of directors authorized a share repurchase program for an aggregate amount of up to $100,000 . The shares may be repurchased from time to time in the open market or through privately negotiated transactions. The repurchase program is subject to business and market conditions and may be suspended or discontinued at any time. Additionally, shares are sometimes withheld from certain employees and nonemployee directors to pay taxes associated with the vesting of restricted stock. These withheld shares are not issued or considered common stock repurchases under our authorized share repurchase program. Through December 31, 2015 , 300,000 shares had been repurchased under this program at a total cost of $7,071 , or an average price of $23.57 per share. No shares were repurchased during the years ended December 31, 2015 , 2014 and 2013 . |

Other Commitments and Contingencies We are contingently liable to surety insurance companies in the amount of $223,441 relative to bonds issued on our behalf to the Bureau of Ocean Energy Management (the “BOEM”), federal and state agencies and certain third parties from which we purchased oil and gas working interests. The bonds represent guarantees by the surety insurance companies that we will operate in accordance with applicable rules and regulations and perform certain plugging and abandonment obligations as specified by applicable working interest purchase and sale agreements. In connection with our exploration and development efforts, we are contractually committed to the use of drilling rigs and the acquisition of seismic data in the aggregate amount of $185,680 to be incurred over the next 3 years. The Oil Pollution Act (the “OPA”) imposes ongoing requirements on a responsible party, including the preparation of oil spill response plans and proof of financial responsibility to cover environmental cleanup and restoration costs that could be incurred in connection with an oil spill. Under the OPA and a final rule adopted by the BOEM in August 1998, responsible parties of covered offshore facilities that have a worst case oil spill of more than 1,000 barrels must demonstrate financial responsibility in amounts ranging from at least $10,000 in specified state waters to at least $35,000 in Outer Continental Shelf ("OCS") waters, with higher amounts of up to $150,000 in certain limited circumstances where the BOEM believes such a level is justified by the risks posed by the operations, or if the worst case oil-spill discharge volume possible at the facility may exceed the applicable threshold volumes specified under the BOEM’s final rule. In addition, the BOEM has finalized rules that raise OPA's damages liability cap from $75,000 to $133,650 . In September 2015, the BOEM issued its "Draft Guidance" describing revised supplemental bonding procedures the agency plans to use to impose financial assurance obligations for decommissioning activities on the federal OCS. Once the Draft Guidance is finalized, the BOEM will issue these supplemental bonding changes in a revised Notice to Lessees (" NTL") in replacement of an existing NTL on supplemental bonding that was made effective on August 28, 2008. Among other things, the Draft Guidance proposes to eliminate the “waiver” exemption currently allowed by BOEM, whereby certain operators on the OCS projecting a relatively large net worth and meeting certain other criteria have the option of being exempted from posting bonds or other acceptable assurances for such operator’s decommissioning obligations. Currently, qualifying operators may self-insure to meet supplemental bonding requirements, but only so long as the cumulative decommissioning liability amount being self-insured by the operator is no more than 50% of the operator’s net worth. Under the Draft Guidance, this waiver option would be eliminated and operators would only be able to self-insure for an amount that is no more than 10% of their tangible net worth. Litigation We are named as a party in certain lawsuits and regulatory proceedings arising in the ordinary course of business. We do not expect that these matters, individually or in the aggregate, will have a material adverse effect on our financial condition. On August 2, 2013, Kimmeridge Energy Exploration Fund, L.P. (“Kimmeridge”) filed a lawsuit against Stone in the 15t h Judicial District Court in Lafayette Parish, Louisiana seeking damages in the amount of $18,373 plus interest, costs and attorney fees. Kimmeridge alleged that Stone was obligated to pay Kimmeridge (1) $1,119 for brokerage costs incurred pursuant to a letter of understanding and (2) $17,254 pursuant to a letter of intent which, according to Kimeridge's pleadings, required Stone to negotiate in good faith and close an acquisition of mineral interests in the Illinois basin. The court granted summary judgment in favor of Stone, limiting damages on Kimmeridge’s $17,254 claim to $1,000 and reducing Stone's exposure at trial for both claims to $2,119 . During the three months ended June 30, 2015, Stone and Kimmeridge settled both claims for an amount within the previously disclosed range of loss (between $0 and $2,119 ). |

Compensation Related Costs [Abstract] | |
EMPLOYEE BENEFIT PLANS | EMPLOYEE BENEFIT PLANS: We have entered into deferred compensation and disability agreements with certain of our current and former officers. The benefits under the deferred compensation agreements vest after certain periods of employment, and at December 31, 2015 , the liability for such vested benefits was approximately $1,125 and is recorded in current and other long-term liabilities. The following is a brief description of each incentive compensation plan applicable to our employees: Annual Cash Incentive Compensation Plan The Amended and Restated Revised Annual Incentive Compensation Plan, which was adopted in November 2007, provides for annual cash incentive bonuses that are tied to the achievement of certain strategic objectives as defined by our board of directors on an annual basis. Stone incurred expenses of $2,242 , $10,361 , and $15,340 , net of amounts capitalized, for each of the years ended December 31, 2015 , 2014 and 2013 , respectively, related to incentive compensation bonuses to be paid under the revised plan. Stock Incentive Plans We currently maintain the Stone Energy Corporation 2009 Amended and Restated Stock Incentive Plan, as amended from time to time (the “2009 Plan”). The 2009 Plan was originally approved at the 2009 Annual Meeting of Stockholders and is an amendment and restatement of the company’s 2004 Amended and Restated Stock Incentive Plan (the “2004 Plan”), and it supersedes and replaces in its entirety the 2004 Plan. The 2009 Plan provides for the granting of (a) “incentive” stock options as defined in Section 422 of the Code, (b) stock options that do not constitute incentive stock options (“non-statutory” stock options), (c) stock appreciation rights in conjunction with an incentive or non-statutory stock option, (d) restricted stock, (e) restricted stock units, (f) dividend equivalents, (g) other stock-based awards, (h) conversion awards, and (i) cash awards, any of which may be further designated as performance awards (collectively referred to as “awards”). The 2009 Plan eliminated the automatic grant of stock options or restricted stock awards to nonemployee directors that was provided for in the 2004 Plan so that awards under the 2009 Plan are entirely at the discretion of our board of directors or a designated committee. All options must have an exercise price of not less than the fair market value of our common stock on the date of grant and may not be re-priced without stockholder approval. At the 2015 Annual Meeting of Stockholders, the stockholders approved the Second Amendment (the “Second Amendment”) to the 2009 Plan and the Third Amendment (the "Third Amendment") to the 2009 Plan. The Second Amendment provides, among other things, for an increase in the number of shares of our common stock reserved for issuance under the 2009 Plan by 1,600,000 shares, effective May 21, 2015, and for an extension of the term of the 2009 Plan to May 21, 2025. The Third Amendment sets forth the material terms of the 2009 Plan (i.e., the eligible employees, business criteria and maximum annual per person compensation limits) for purposes of complying with certain requirements of Section 162(m) of the Internal Revenue Code. The Third Amendment does not change the employees eligible to receive compensation under the 2009 Plan, but does (i) allow Stone to grant cash awards (which may or may not be designated as performance awards) under the 2009 Plan, (ii) impose a fixed share number limit on stock-based awards and a fixed dollar limit on cash awards granted during any calendar year under the 2009 Plan to certain individuals, and (iii) add additional business criteria that may be utilized in setting performance goals under the 2009 Plan. The Third Amendment also became effective as of May 21, 2015. On December 17, 2015, Stone amended and restated the 2009 Plan to incorporate all prior amendments to the 2009 Plan (including the Second Amendment and the Third Amendment) and certain other non-material changes to the 2009 Plan. At December 31, 2015 , we had approximately 2,082,434 additional shares available for issuance pursuant to the 2009 Plan. 401(k) and Deferred Compensation Plans The Stone Energy 401(k) Profit Sharing Plan provides eligible employees with the option to defer receipt of a portion of their compensation and we may, at our discretion, match a portion or all of the employee’s deferral. The amounts held under the plan are invested in various investment funds maintained by a third party in accordance with the direction of each employee. An employee is 20% vested in matching contributions (if any) for each year of service and is fully vested upon five years of service. For the years ended December 31, 2015 , 2014 and 2013 , Stone contributed $1,553 , $1,989 and $1,793 , respectively, to the plan. The Stone Energy Corporation Deferred Compensation Plan provides eligible executives and employees with the option to defer up to 100% of their eligible compensation for a calendar year and we may, at our discretion, match a portion or all of the participant’s deferral based upon a percentage determined by our board of directors. In addition, the Board may elect to make discretionary profit sharing contributions to the plan. To date there have been no matching or discretionary profit sharing contributions made by Stone. The amounts held under the plan are invested in various investment funds maintained by a third party in accordance with the direction of each participant. At December 31, 2015 and 2014 , plan assets of $8,499 and $8,425 , respectively, were included in other assets. An equal amount of plan liabilities were included in other long-term liabilities. Change of Control and Severance Plans On April 7, 2009, we amended and restated our Executive Change of Control and Severance Plan effective as of December 31, 2008 (as so amended and restated, the “Executive Plan”). The Executive Plan also replaced and superseded our Executive Change in Control and Severance Policy that was maintained for certain designated executives (specifically, the CEO and CFO). The Executive Plan will provide the company’s officers that are terminated in the event of a change of control and upon certain other terminations of employment with change of control and severance benefits as defined in the Executive Plan. Although our CEO does not currently participate in the Executive Plan, the severance benefits provided to him under his employee agreement are substantially similar to the benefits provided under the Executive Plan. Executives who are terminated within the scope of the Executive Plan will be entitled to certain payments and benefits including the following: (i) any unpaid base salary up to the date of termination; (ii) in the case of the CEO and CFO, a lump sum severance payment of 2.99 times the sum of the executive’s annual base salary and any target bonus at the one hundred percent level; (iii) a lump sum amount representing a pro rata share of the bonus opportunity up to the date of termination at the then projected rate of payout; (iv) in the case of officers other than the CEO and CFO and an involuntary termination occurring outside a change of control period, a lump sum severance payment in an amount equal to the executive’s annual base salary; (v) in the case of officers other than the CEO and CFO and an involuntary termination occurring during a change of control period, a lump sum severance payment in an amount equal to 2.99 times the executive’s annual base salary; (vi) continued health plan coverage for six months and outplacement services. In the case of the CEO and CFO, if the payments would be “excess parachute payments,” the CEO and CFO may receive a potential gross-up payment to reimburse them for excise taxes that might be incurred under Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as any additional income taxes resulting from such reimbursement, provided that if it shall be determined that the executive is entitled to a gross-up payment but the total to be paid does not exceed 110% of the greatest amount (the “Reduced Amount”) that could be paid such that receipt of the total would not give rise to any excise tax, then no gross-up will be paid and the total payments to the executive will be reduced to the Reduced Amount. Also, if a payment would be to a “specified employee” for purposes of Section 409A of the Code, payment will be delayed until six months after his termination if required to comply with Section 409A. Benefits paid upon a change of control, without regard to whether there is a termination of employment, include the following: (i) lapse of restrictions on restricted stock, (ii) accelerated vesting and cash-out of all in-the-money stock options, (iii) a 401(k) plan employer matching contribution at the rate of 50% , and (iv) a pro-rated portion of the projected bonus, if any, for the year of change of control. On December 7, 2007, our board of directors approved and adopted the Stone Energy Corporation Employee Change of Control Severance Plan (“Employee Severance Plan”), as amended and restated to comply with the final regulations under Section 409A of the Code and to provide that said plan will remain in force and effect unless and until terminated by our board of directors. The Employee Severance Plan amended and restated the company’s previous Employee Change of Control Severance Plan dated November 16, 2006. The Employee Severance Plan covers all full-time employees other than officers. Severance is triggered by an involuntary termination of employment on and during the six-month period following a change of control, including a resignation by the employee relating to a change in duties. Employees who are terminated within the scope of the Employee Severance Plan will be entitled to certain payments and benefits including the following: (i) a lump sum equal to (1) weekly pay times full years of service, plus (2) one week’s pay for each full $10,000 of annual pay, but the sum of (1) and (2) cannot be less than 12 weeks of pay or greater than 52 weeks of pay; (ii) continued health plan coverage for 6 months ; (iii) a pro-rated portion of the employee’s targeted bonus for the year, and (iv) reasonable outplacement services consistent with current HR practices. Benefits paid upon a change of control, without regard to whether there is a termination of employment, include the following: (i) lapse of restrictions on restricted stock, (ii) cash-out of in-the-money stock options, (iii) a 401(k) plan employer matching contribution at the rate of 50% , and (iv) a lump sum cash payment equal to the product of (1) the number of “restricted shares” of company stock that the employee would have received under the company’s stock plan but did not receive for the time-vested portion of his long-term stock incentive award, if any, for the calendar year in which the change of control occurs times (2) the price per share of the company’s common stock utilized in effecting the change of control, provided that such amount shall be pro-rated by multiplying such amount by the number of full months that have elapsed from January 1 of that calendar year to the effective date of the change of control and then dividing the result by 12. |

SUPPLEMENTAL INFORMATION ON OIL AND NATURAL GAS OPERATIONS - UNAUDITED | SUPPLEMENTAL INFORMATION ON OIL AND NATURAL GAS OPERATIONS – UNAUDITED: At December 31, 2015 , 2014 and 2013 , our oil and gas properties were located in the United States and Canada. Costs Incurred The following table discloses certain financial data relative to our oil and gas producing activities located onshore and offshore in the continental United States: Year Ended December 31, 2015 2014 2013 Oil and gas properties – United States, proved and unevaluated: Balance, beginning of year $ 9,348,054 $ 8,517,873 $ 7,692,261 Costs incurred during the year (capitalized): Acquisition costs, net of sales of unevaluated properties (14,158 ) 44,634 70,903 Exploratory costs 104,169 270,850 297,113 Development costs (1) 266,982 438,334 378,242 Salaries, general and administrative costs 27,984 33,975 32,815 Interest 41,339 45,722 46,860 Less: overhead reimbursements (913 ) (3,334 ) (321 ) Total costs incurred during the year, net of divestitures 425,403 830,181 825,612 Balance, end of year $ 9,773,457 $ 9,348,054 $ 8,517,873 Accumulated DD&A: Balance, beginning of year $ (6,970,631 ) $ (5,908,760 ) $ (5,510,166 ) Provision for DD&A (277,088 ) (335,987 ) (346,827 ) Write-down of oil and gas properties (1,314,817 ) (351,192 ) — Sale of proved properties 1,064 (374,692 ) (51,767 ) Balance, end of year $ (8,561,472 ) $ (6,970,631 ) $ (5,908,760 ) Net capitalized costs – United States, proved and unevaluated $ 1,211,985 $ 2,377,423 $ 2,609,113 DD&A per Mcfe $ 3.19 $ 3.59 $ 3.43 (1) Includes capitalized asset retirement costs of ($43,901), ($20,305) and $54,737, respectively. Costs incurred during the year (expensed): Lease operating expenses $ 100,139 $ 176,495 $ 201,153 Transportation, processing and gathering expenses 58,847 64,951 42,172 Production taxes 6,877 12,151 15,029 Accretion expense 25,988 28,411 33,575 Expensed costs – United States $ 191,851 $ 282,008 $ 291,929 Under the full cost method of accounting, we compare, at the end of each financial reporting period, the present value of estimated future net cash flows from proved reserves (adjusted for hedges and excluding cash flows related to estimated abandonment costs) to the net capitalized costs of proved oil and gas properties, net of related deferred taxes. We refer to this comparison as a ceiling test. If the net capitalized costs of proved oil and gas properties exceed the estimated discounted future net cash flows from proved reserves, we are required to write down the value of our oil and gas properties to the value of the discounted cash flows. At March 31, 2015, our ceiling test computation resulted in a write-down of our U.S. oil and gas properties of $491,412 based on 12-month average prices, net of applicable differentials, of $78.99 per Bbl of oil, $2.96 per Mcf of natural gas and $28.82 per Bbl of natural gas liquids ("NGLs"). At June 30, 2015, our ceiling test computation resulted in a write-down of our U.S. oil and gas properties of $179,125 based on 12-month average prices, net of applicable differentials, of $68.68 per Bbl of oil, $2.47 per Mcf of natural gas and $29.13 per Bbl of NGLs. At September 30, 2015, our ceiling test computation resulted in a write-down of our U.S. oil and gas properties of $295,679 based on 12-month average prices, net of applicable differentials, of $57.76 per Bbl of oil, $2.44 per Mcf of natural gas and $23.04 per Bbl of NGLs. At December 31, 2015, our ceiling test computation resulted in a write-down of our U.S. oil and gas properties of $348,601 based on 12-month average prices, net of applicable differentials, of $51.16 per Bbl of oil, $2.19 per Mcf of natural gas and $16.40 per Bbl of NGLs. The March 31, June 30, September 30 and December 31, 2015 write-downs were decreased by $28,687 , $47,784 , $42,652 and $24,797 , respectively, as a result of hedges. At September 30, 2014, our ceiling test computation resulted in a write-down of our U.S. oil and gas properties of $47,130 based on 12-month average prices, net of applicable differentials, of $94.94 per Bbl of oil, $4.19 per Mcf of natural gas and $41.33 per Bbl of NGLs. At December 31, 2014, our ceiling test computation resulted in a write-down of our U.S. oil and gas properties of $304,062 based on 12-month average prices, net of applicable differentials, of $89.46 per Bbl of oil, $3.68 per Mcf of natural gas and $36.79 per Bbl of NGLs. The September 30 and December 31, 2014 write-downs were increased by $29,001 and $13,342 , respectively, as a result of hedges. The following table discloses net costs incurred (evaluated) on our unevaluated properties located in the United States for the years indicated: Year Ended December 31, Unevaluated oil and gas properties – United States: 2015 2014 2013 Net costs incurred (evaluated) during year: Acquisition costs $ (115,767 ) $ (42,384 ) $ 30,271 Exploration costs (16,315 ) (186,308 ) 188,830 Capitalized interest 41,339 45,722 46,860 $ (90,743 ) $ (182,970 ) $ 265,961 During 2013, we entered into an agreement to participate in the drilling of exploratory wells in Canada. Upon a more complete evaluation of this project and in response to the significant decline in commodity prices over the last year, we have discontinued our business development effort in Canada. Accordingly, we recognized a full impairment of our Canadian oil and gas properties in 2015. The following table discloses certain financial data relative to our oil and gas activities located in Canada: Year Ended December 31, 2015 2014 2013 Oil and gas properties – Canada: Balance, beginning of year $ 36,579 $ 10,583 $ — Costs incurred during the year (capitalized): Acquisition costs (2,862 ) 6,956 8,764 Exploratory costs 8,767 19,040 1,819 Total costs incurred during the year 5,905 25,996 10,583 Balance, end of year (fully evaluated at December 31, 2015 and unevaluated at December 31, 2014 and 2013) $ 42,484 $ 36,579 $ 10,583 Accumulated DD&A: Balance, beginning of year $ — $ — $ — Foreign currency translation adjustment 5,146 $ — — Write-down of oil and gas properties (47,630 ) $ — — Balance, end of year $ (42,484 ) $ — $ — Net capitalized costs – Canada $ — $ 36,579 $ 10,583 The following table discloses financial data associated with unevaluated costs (United States) at December 31, 2015 : Balance as of Net Costs Incurred During the Year Ended December 31, December 31, 2015 2015 2014 2013 2012 and prior Acquisition costs $ 173,902 $ (33,623 ) $ (5,118 ) $ 40,535 $ 172,108 Exploration costs 148,518 41,936 42,899 42,186 21,497 Capitalized interest 117,623 20,257 23,538 24,162 49,666 Total unevaluated costs $ 440,043 $ 28,570 $ 61,319 $ 106,883 $ 243,271 Approximately 95 specifically identified drilling projects are included in unevaluated costs at December 31, 2015 and are expected to be evaluated in the next four years. The excluded costs will be included in the amortization base as the properties are evaluated and proved reserves are established or impairment is determined. Interest costs capitalized on unevaluated properties during the years ended December 31, 2015 , 2014 and 2013 totaled $41,339 , $45,722 and $46,860 , respectively. Proved Oil and Natural Gas Quantities Our estimated net proved oil and natural gas reserves at December 31, 2015 have been prepared in accordance with guidelines established by the Securities and Exchange Commission (“SEC”). Accordingly, the following reserve estimates are based upon existing economic and operating conditions at the respective dates. There are numerous uncertainties inherent in estimating quantities of proved reserves and in providing the future rates of production and timing of development expenditures. The following reserve data represents estimates only and should not be construed as being exact. In addition, the present values should not be construed as the market value of the oil and gas properties or the cost that would be incurred to obtain equivalent reserves. The following table sets forth an analysis of the estimated quantities of net proved oil (including condensate), natural gas and NGL reserves, all of which are located onshore and offshore the continental United States. Estimated proved oil, natural gas and NGL reserves at December 31, 2015 , 2014 and 2013 are prepared in accordance with the SEC’s rule, “Modernization of Oil and Gas Reporting,” using a historical 12-month average pricing assumption. Oil (MBbls) NGLs (MBbls) Natural Gas (MMcf) Oil, Natural Gas and NGLs (MMcfe) Estimated proved reserves as of December 31, 2012 44,918 18,066 395,374 773,285 Revisions of previous estimates 3,606 2,439 36,006 72,275 Extensions, discoveries and other additions 2,367 4,395 79,729 120,299 Sale of reserves (170 ) — (214 ) (1,235 ) Production (6,894 ) (1,603 ) (50,129 ) (101,111 ) Estimated proved reserves as of December 31, 2013 43,827 23,297 460,766 863,513 Revisions of previous estimates (624 ) (331 ) (4,631 ) (10,362 ) Extensions, discoveries and other additions 9,650 7,521 131,617 234,639 Sale of reserves (4,888 ) (556 ) (46,483 ) (79,151 ) Production (5,568 ) (2,114 ) (47,426 ) (93,515 ) Estimated proved reserves as of December 31, 2014 42,397 27,817 493,843 915,124 Revisions of previous estimates (6,818 ) (20,777 ) (362,102 ) (527,675 ) Extensions, discoveries and other additions 862 11 1,499 6,738 Purchase of producing properties 685 1,808 26,136 41,095 Sale of reserves (859 ) — (1,061 ) (6,213 ) Production (5,991 ) (2,401 ) (36,457 ) (86,809 ) Estimated proved reserves as of December 31, 2015 30,276 6,458 121,858 342,260 Estimated proved developed reserves: as of December 31, 2013 27,920 11,569 246,946 483,885 as of December 31, 2014 22,957 13,743 249,924 470,118 as of December 31, 2015 21,734 4,784 90,262 249,366 Estimated proved undeveloped reserves: as of December 31, 2013 15,907 11,728 213,820 379,628 as of December 31, 2014 19,440 14,074 243,919 445,006 as of December 31, 2015 8,542 1,674 31,596 92,894 The following narrative provides the reasons for the significant changes in the quantities of our estimated proved reserves by year. Year Ended December 31, 2015. Revisions of previous estimates were primarily the result of the significant decline in commodity prices resulting in uneconomic reserves ( 570 Bcfe) primarily in Appalachia, slightly offset by positive well performance ( 42 Bcfe). Purchase of producing properties related to increases in our net revenue and working interests in multiple wells in the Mary field in Appalachia resulting from the finalization of participation elections made by partners and potential partners in certain units. Year Ended December 31, 2014. Extensions, discoveries and other additions were primarily the result of our Appalachia ( 118 Bcfe) and our deep water ( 116 Bcfe) drilling programs. Sale of reserves primarily related to the sale of certain of our non-core GOM conventional shelf properties ( 63 Bcfe) and our Katie field in Appalachia ( 15 Bcfe). Year Ended December 31, 2013. Extensions, discoveries and other additions were primarily the result of our Appalachia drilling program ( 117 Bcfe). Revisions of previous estimates were primarily the result of positive reserve report pricing changes extending the economic limits of reservoirs ( 18 Bcfe) and well performance ( 55 Bcfe). Standardized Measure of Discounted Future Net Cash Flow The following tables present the standardized measure of discounted future net cash flows related to estimated proved oil, natural gas and NGL reserves together with changes therein, including a reduction for estimated plugging and abandonment costs that are also reflected as a liability on the balance sheet at December 31, 2015 . You should not assume that the future net cash flows or the discounted future net cash flows, referred to in the tables below, represent the fair value of our estimated oil, natural gas and NGL reserves. Prices are based on either the historical 12-month average price based on closing prices on the first day of each month, or prices defined by existing contractual arrangements.

Accounting Changes and Error Corrections [Abstract] | |
RECENTLY ISSUED ACCOUNTING STANDARDS | RECENTLY ISSUED ACCOUNTING STANDARDS: In May 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers ” to clarify the principles for recognizing revenue and to develop a common revenue standard and disclosure requirements. The standard may be applied retrospectively or using a modified retrospective approach, with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. In August 2015, the FASB issued ASU 2015-14, deferring the effective date of ASU 2014-09 by one year. As a result, the standard is effective for interim and annual periods beginning on or after December 31, 2017. Although we are still evaluating the effect that this new standard may have on our financial statements and related disclosures, we do not anticipate that the implementation of this new standard will have a material effect. In August 2014, the FASB issued ASU 2014-15, " Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40)" . The guidance will require management to evaluate whether there are conditions and events that raise substantial doubt about the company's ability to continue as a going concern within one year after the financial statements are issued on both an interim and annual basis. Additionally, management will be required to provide certain footnote disclosures if it concludes that substantial doubt exists or when it plans to alleviate substantial doubt about the company's ability to continue as a going concern. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and for annual and interim periods thereafter. |

ORGANIZATION AND SUMMARY OF S28
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended |
Dec. 31, 2015 | |
Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation: The financial statements include our accounts and the accounts of our wholly owned subsidiaries, Stone Energy Offshore, L.L.C. (“Stone Offshore”), Stone Energy Holding, L.L.C., Stone Energy Canada, U.L.C., SEO A LLC and SEO B LLC. All intercompany balances have been eliminated. |
Use of Estimates | Use of Estimates: The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates are used primarily when accounting for depreciation, depletion and amortization (“DD&A”) expense, unevaluated property costs, estimated future net cash flows from proved reserves, costs to abandon oil and gas properties, income taxes, accruals of capitalized costs, operating costs and production revenue, capitalized general and administrative costs and interest, insurance recoveries, effectiveness and estimated fair value of derivative contracts, estimates of fair value in business combinations and contingencies. |
Fair Value Measurements | Fair Value Measurements: U.S. GAAP establishes a framework for measuring fair value and requires certain disclosures about fair value measurements. As of December 31, 2015 and 2014 , we held certain financial assets and liabilities that are required to be measured at fair value on a recurring basis, including our commodity derivative instruments and our investments in marketable securities. |
Hybrid Debt Instruments | Hybrid Debt Instruments: In 2012, we issued $300,000 in aggregate principal amount of 1 3 ⁄ 4 % Senior Convertible Notes due 2017 (the “2017 Convertible Notes”). See Note 11 – Long-Term Debt . On that same day we entered into convertible note hedging transactions which are expected to reduce the potential dilution to our common shareholders upon conversion of the notes. In accordance with Accounting Standards Codification (“ASC”) 480-20 and ASC 470, we accounted for the debt and equity portions of the notes in a manner that will reflect our nonconvertible borrowing rate when interest is recognized in subsequent periods. This results in the separation of the debt component, classification of the remaining component in stockholders’ equity, and accretion of the resulting discount as interest expense. Additionally, the hedging transactions meet the criteria for classification as equity transactions and were recorded as such. |
Cash and Cash Equivalents | Cash and Cash Equivalents: We consider all money market funds and highly liquid investments in overnight securities through our commercial bank accounts, which result in available funds on the next business day, to be cash and cash equivalents. |
Oil and Gas Properties | Oil and Gas Properties: We follow the full cost method of accounting for oil and gas properties. Under this method, all acquisition, exploration, development and estimated abandonment costs, including certain related employee and general and administrative costs (less any reimbursements for such costs) and interest incurred for the purpose of finding oil and gas are capitalized. Such amounts include the cost of drilling and equipping productive wells, dry hole costs, lease acquisition costs, delay rentals and other costs related to such activities. Employee, general and administrative costs that are capitalized include salaries and all related fringe benefits paid to employees directly engaged in the acquisition, exploration and development of oil and gas properties, as well as all other directly identifiable general and administrative costs associated with such activities, such as rentals, utilities and insurance. We capitalize a portion of the interest costs incurred on our debt based upon the balance of our unevaluated property costs and our weighted-average borrowing rate. Employee, general and administrative costs associated with production operations and general corporate activities are expensed in the period incurred. Additionally, workover and maintenance costs incurred solely to maintain or increase levels of production from an existing completion interval are charged to lease operating expense in the period incurred. U.S. GAAP allows the option of two acceptable methods for accounting for oil and gas properties. The successful efforts method is the allowable alternative to the full cost method. The primary differences between the two methods are in the treatment of exploration costs, the computation of DD&A expense and the assessment of impairment of oil and gas properties. Under the full cost method, all exploratory costs are capitalized, while under the successful efforts method, exploratory costs associated with unsuccessful exploratory wells and all geological and geophysical costs are expensed. Under the full cost method, DD&A expense is computed on cost centers represented by entire countries, while under the successful efforts method, cost centers are represented by properties, or some reasonable aggregation of properties with common geological structural features or stratigraphic condition, such as fields or reservoirs. Under the full cost method, oil and gas properties are subject to the ceiling test as discussed below while under the successful efforts method oil and gas properties are assessed for impairment in accordance with ASC 360. We amortize our investment in oil and gas properties through DD&A expense using the units of production (the “UOP”) method. Under the UOP method, the quarterly provision for DD&A expense is computed by dividing production volumes for the period by the total proved reserves as of the beginning of the period (beginning of period reserves being determined by adding production to the end of period reserves), and applying the respective rate to the net cost of proved oil and gas properties, including future development costs. Under the full cost method, we compare, at the end of each financial reporting period, the present value of estimated future net cash flows from proved reserves (adjusted for hedges and excluding cash flows related to estimated abandonment costs) to the net capitalized costs of proved oil and gas properties, net of related deferred taxes. We refer to this comparison as a ceiling test. If the net capitalized costs of proved oil and gas properties exceed the estimated discounted future net cash flows from proved reserves, we are required to write down the value of our oil and gas properties to the value of the discounted cash flows. Sales of oil and gas properties are accounted for as adjustments to net oil and gas properties with no gain or loss recognized, unless the adjustment would significantly alter the relationship between capitalized costs and proved reserves. |
Asset Retirement Obligations | Asset Retirement Obligations: U.S. GAAP requires us to record our estimate of the fair value of liabilities related to future asset retirement obligations in the period the obligation is incurred. Asset retirement obligations relate to the removal of facilities and tangible equipment at the end of an oil and gas property’s useful life. The application of this rule requires the use of management’s estimates with respect to future abandonment costs, inflation, market risk premiums, useful life and cost of capital. U.S. GAAP requires that our estimate of our asset retirement obligations does not give consideration to the value the related assets could have to other parties. |
Other Property and Equipment | Other Property and Equipment: Our office buildings in Lafayette, Louisiana are being depreciated on the straight-line method over their estimated useful lives of 39 years. |
Inventory | Inventory: We maintain an inventory of tubular goods. Items remain in inventory until dedicated to specific projects, at which time they are transferred to oil and gas properties. Items are carried at the lower of cost or market based on the specific identification method. |
Earnings Per Common Share | Earnings Per Common Share: Under U.S. GAAP, certain instruments granted in share-based payment transactions are considered participating securities prior to vesting and are therefore required to be included in the earnings allocation in calculating earnings per share under the two-class method. Companies are required to treat unvested share-based payment awards with a right to receive non-forfeitable dividends as a separate class of securities in calculating earnings per share. |
Production Revenue | Production Revenue: We recognize production revenue under the entitlements method of accounting. Under this method, revenue is deferred for deliveries in excess of our net revenue interest, while revenue is accrued for undelivered or underdelivered volumes. Production imbalances are generally recorded at the estimated sales price in effect at the time of production. |
Income Taxes | Income Taxes: Provisions for income taxes include deferred taxes resulting primarily from temporary differences due to different reporting methods for oil and gas properties for financial reporting and income tax purposes. For financial reporting purposes, all exploratory and development expenditures related to evaluated projects, including future abandonment costs, are capitalized and amortized using the UOP method. For income tax purposes, only the leasehold, geological and geophysical and equipment relative to successful wells are capitalized and recovered through DD&A, although for 2013 , 2014 and 2015 , special provisions allowed for current deductions for the cost of certain equipment. Generally, most other exploratory and development costs are charged to expense as incurred; however, we follow certain provisions of the Internal Revenue Code that allow capitalization of intangible drilling costs where management deems appropriate. Other financial and income tax reporting differences occur as a result of statutory depletion, different reporting methods for sales of oil and gas reserves in place, different reporting methods used in the capitalization of employee, general and administrative and interest expense, and different reporting methods for employee compensation. |
Derivative Instruments and Hedging Activities | Derivative Instruments and Hedging Activities: The nature of a derivative instrument must be evaluated to determine if it qualifies as a hedging instrument. If the instrument qualifies as a hedging instrument, it is recorded as either an asset or liability measured at fair value and subsequent changes in the derivative’s fair value are recognized in stockholders’ equity through other comprehensive income (loss), net of related taxes, to the extent the hedge is considered effective. Monthly settlements of effective hedges are reflected in revenue from oil and natural gas production and cash flows from operating activities. Instruments not qualifying as hedging instruments are recorded in our balance sheet at fair value and subsequent changes in fair value are recognized in earnings through derivative expense (income). Monthly settlements of ineffective hedges and derivative instruments not qualifying as hedging instruments are recognized in earnings through derivative expense (income) and cash flows from operating activities. |
Share-Based Compensation | Share-Based Compensation: We record share-based compensation using the grant date fair value of issued stock options and restricted stock over the vesting period of the instrument. We utilize the Black-Scholes option pricing model to measure the fair value of stock options. The fair value of restricted shares is typically determined based on the average of our high and low stock prices on the grant date. |
Recently Issued Accounting Standards | RECENTLY ISSUED ACCOUNTING STANDARDS: In May 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers ” to clarify the principles for recognizing revenue and to develop a common revenue standard and disclosure requirements. The standard may be applied retrospectively or using a modified retrospective approach, with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. In August 2015, the FASB issued ASU 2015-14, deferring the effective date of ASU 2014-09 by one year. As a result, the standard is effective for interim and annual periods beginning on or after December 31, 2017. Although we are still evaluating the effect that this new standard may have on our financial statements and related disclosures, we do not anticipate that the implementation of this new standard will have a material effect. In August 2014, the FASB issued ASU 2014-15, " Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40)" . The guidance will require management to evaluate whether there are conditions and events that raise substantial doubt about the company's ability to continue as a going concern within one year after the financial statements are issued on both an interim and annual basis. Additionally, management will be required to provide certain footnote disclosures if it concludes that substantial doubt exists or when it plans to alleviate substantial doubt about the company's ability to continue as a going concern. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and for annual and interim periods thereafter. |
