The moratoria were lifted October 12, 2010, but the BOEMRE has not approved new drilling permits. At December 31, 2010, no significant impairment of these properties had been recognized as a result of the moratoria and the Company intends to continue exploration and development of these properties. During the fourth quarter 2010, $46 million of exploratory drilling costs related to the Macondo well were charged to exploration expense. See Note 15.       During 2010, the Company recognized impairments of $147 million related to long-lived assets. These impairments include $114 million related to a production platform included in the oil and gas exploration and production operating segment that remains idle with no immediate plan for use, and for which a limited market currently exists. Other long-lived assets included in the oil and gas exploration and production operating segment were impaired by $31 million, which were primarily located in the Southern and Appalachia Region. Certain midstream operating segment assets were impaired by $2 million due to reduced operating activity. These assets were impaired to fair value, which was estimated using Level 3 inputs. Impairments and depreciation reduced the net book value of assets impaired during 2010 to $51 million at December 31, 2010.        During 2009, the Company recognized impairments of $41 million related to long-lived assets, including $22 million related to the oil and gas exploration and production operating segment triggered by the economic and commodity price environment, $7 million associated with certain gathering and processing facilities in the midstream operating segment due to reduced operating activity, and $12 million related to a liquefied natural gas facility site, included in the marketing operating segment. These assets were impaired to fair value, which was estimated using Level 3 inputs. Impairments and depreciation reduced the net book value of assets impaired in 2009 to $26 million at December 31, 2009.        During 2008, the Company recognized impairments of $211 million, including $113 million associated with properties in the United States included in the oil and gas exploration and production operating segment, and $98 million associated with certain gathering and processing facilities in the United States included in the midstream operating segment. These impairments resulted primarily from lower commodity prices at year-end 2008.Suspended Exploratory Drilling Costs   If an exploratory well provides evidence to justify potential completion as a producing well, drilling costs associated with the well are initially capitalized, or suspended, pending a determination as to whether a commercially sufficient quantity of proved reserves can be attributed to the area as a result of drilling. This determination may take longer than one year in certain areas (generally, deepwater and international locations) depending on, among other things, the amount of hydrocarbons discovered, the outcome of planned geological and engineering studies, the need for additional appraisal drilling activities to determine whether the discovery is sufficient to support an economic development plan, and government sanctioning of development activities in certain international locations.        At the end of each quarter, management reviews the status of all suspended exploratory drilling costs in light of ongoing exploration activities—in particular, whether the Company is making sufficient progress in its ongoing exploration and appraisal efforts or, in the case of discoveries requiring government sanctioning, whether development negotiations are underway and proceeding as planned. If management determines that future appraisal drilling or development activities are unlikely to occur, associated suspended exploratory drilling costs are expensed in that period.       The following table presents the amount of suspended exploratory drilling costs related to continuing operations at December 31 for each of the last three years, and changes to those amounts during the years then ended. The table excludes amounts capitalized and subsequently reclassified to proved oil and gas properties or charged to expense within the same year.<div><table style="border-collapse:collapse;margin-top:20px;"><tr style="height: 18px"><td style="width: 472px;

The international projects with costs suspended for longer than one year are primarily suspended pending the results of additional appraisal activities and submission of a development plan. Management believes projects with suspended exploratory drilling costs exhibit sufficient quantities of hydrocarbons to justify potential development and is actively pursuing efforts to assess whether reserves can be attributed to the respective areas. The costs associated with deepwater Gulf of Mexico projects are suspended pending the completion of economic evaluations including, but not limited to, results of additional appraisal drilling, facilities, infrastructure, well-test analysis, additional geological and geophysical data, development plan approval, and permitting. If additional information becomes available that raises substantial doubt as to the economic or operational viability of any of these projects, the associated costs will be expensed at that time.5.  Properties and Equipment        A summary of the cost of properties and equipment by function as offalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDisclosure of long-lived, physical assets that are used in the normal conduct of business to produce goods and services and not intended for resale.
