Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsDivestiture of Permian Basin Properties. On November 1, 2018, the Company sold substantially all of its oil and natural gas properties, rights and related assets in the Central Basin Platform ("CBP") region of the Permian Basin, primarily located in Andrews County, TX, along with 13,125,000 common units representing a 25% equity interest in the SandRidge Permian Trust (the "Permian Trust"), to an independent third party for $14.5 million in cash, subject to certain remaining post-closing adjustments. The CBP assets and interest in the Permian Trust include 1,066 producing wells within the Permian Trust's area of mutual interest, certain wells not associated with the Permian Trust, a field office, and all equipment, inventory and yards associated with the Company's CBP operations. As a result of this divestiture, the Company will no longer have any obligations associated with the Permian Trust. This transaction did not result in a significant alteration of the relationship between the Company’s capitalized costs and proved reserves and, accordingly, the divestiture will be accounted for as an adjustment to the full cost pool with no gain or loss recognized on the sale. Acquisition of Oil and Natural Gas Interests. On November 2, 2018, the Company acquired certain oil and natural gas properties, rights and related assets in the Mississippian Lime and NW STACK areas of Oklahoma and Kansas for approximately $25.1 million, subject to certain remaining post-closing adjustments. The acquired assets primarily consist of interests in 1,962 wells, approximately 80% of which are operated by the Company, an additional 13.2% working interest in approximately 410,000 gross (54,000 net) acres across the Mid-Continent, and an additional 13.2% working interest ownership in the Company's saltwater gathering and disposal system in the Mississippian Lime.
