Acquisitions and Divestitures [Abstract]
Acquisitions and Divestitures	Divestitures East Texas and Other Properties In August 2015, we sold our East Texas assets and received cash proceeds of approximately $73 million, net of transaction costs and customary closing adjustments. The effective date of the sale was May 1, 2015 and we recognized a gain of approximately $43 million. The carrying value of the net assets disposed in this transaction was $28.5 million, including oil and gas properties and other fixed assets of $32.3 million, net of related asset retirement obligations (“AROs”) of $3.8 million. The net pre-tax operating income (loss) attributable to the East Texas assets was $1.0 million and $(6.9) million for the three months ended September 30, 2015 and 2014 and $1.7 million and $(18.4) million for the nine months ended September 30, 2015 and 2014. The net proceeds from this transactions were used to pay down a portion of our outstanding borrowings under the Revolver. In October 2015, we also sold certain non-core properties in the southwestern portion of our Eagle Ford acreage for approximately $13 million, net of transaction costs and customary closing adjustments. We expect to recognize a loss of approximately $9 million on this transaction in the fourth quarter of 2015. Oil Gathering System Construction Rights In July 2014, we sold the rights to construct a crude oil gathering and intermediate transportation system in South Texas to Republic Midstream, LLC (“Republic”) for proceeds of approximately $147 million, net of transaction costs. Concurrent with the sale, we entered into long-term agreements with Republic to provide us gathering and intermediate transportation services for a substantial portion of our future South Texas crude oil and condensate production. We realized a gain of $147.1 million, of which $63.0 million was recognized upon the closing of the transaction and the remaining $84.1 million was deferred to be recognized over a twenty-five year period beginning after the system has been constructed and is operational, currently expected to be in the first quarter of 2016. In September 2015, the gathering agreement with Republic was amended to reduce the number of wells initially required to be connected to the pipeline system, provide for alternative transportation in areas that will not be served by the pipeline and also reduce the gathering fees. As a result of the amendment, we recognized $8.4 million of deferred gain in September 2015. As of September 30, 2015, $2.3 million of the remaining deferred gain is included as a component of Accounts payable and accrued expenses and $73.5 million, representing the remaining noncurrent portion, is included as a component of Other liabilities on our Condensed Consolidated Balance Sheets. Natural Gas Gathering and Gas Lift Assets In January 2014, we sold our natural gas gathering and gas lift assets in South Texas to American Midstream Partners, LP (“AMID”) for proceeds of approximately $96 million, net of transaction costs. Concurrent with the sale, we entered into a long-term agreement with AMID to provide us natural gas gathering, compression and gas lift services for a substantial portion of our current and future South Texas natural gas production. We realized a gain of $67.3 million, of which $56.7 million was recognized upon the closing of the transaction and the remaining $10.6 million was deferred and is being recognized over a twenty-five year period. We amortized $0.3 million of the deferred gain during each of the nine months ended September 30, 2015 and 2014. As of September 30, 2015, $0.4 million of the remaining deferred gain was included as a component of Accounts payable and accrued expenses and $9.5 million, representing the noncurrent portion, was included as a component of Other liabilities on our Condensed Consolidated Balance Sheets.
