Divestitures [Text Block]	13. Divestitures During the first three months of 2015, EOG received proceeds of approximately $1 million from sales of assets. During the first three months of 2014, EOG received proceeds of approximately $20 million primarily from sales of producing properties and acreage in the Mid-Continent and Rocky Mountain areas. During the fourth quarter of 2014, EOG received proceeds of approximately $400 million from the divestiture of all its assets in Manitoba and the majority of its assets in Alberta (collectively, the Canadian Sales). The Canadian Sales that closed on or about December 1, 2014, occurred in two separate transactions, an asset sale and the sale of the stock of certain of EOG's Canadian subsidiaries. As these two transactions represented a substantially complete liquidation of EOG's Canadian operations, EOG reclassified approximately $383 million of cumulative translation adjustments previously recorded in Accumulated Other Comprehensive Income (Loss) on the Consolidated Balance Sheets to Net Income (Gains on Asset Dispositions, Net) on the Consolidated Statements of Income (Loss) and Comprehensive Income (Loss). The Canadian Sales also resulted in the release of approximately $150 million of restricted cash related to future abandonment liabilities.
