Business Combinations [Abstract]
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.
