U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Reserves. 2007 Annual Report, February 2009

摘要

The U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Reserves 2007 Annual Report is the 31st prepared by the Energy Information Administration (EIA) to fulfill its responsibility to gather and report annual proved reserves estimates. The EIA annual reserves report series is the only source of comprehensive domestic proved reserves estimates. This publication is used by the Congress, Federal and State agencies, industry, and other interested parties to obtain accurate estimates of the Nation's proved reserves of crude oil, natural gas, and natural gas liquids. These data are essential to the development, implementation, and evaluation of energy policy and legislation. This report presents estimates of proved reserves of crude oil, natural gas, and natural gas liquids as of December 31, 2007, as well as production volumes for the United States and producing States and State subdivisions for the year 2007. Estimates are presented for the following four categories of natural gas: total gas (wet after lease separation), nonassociated gas and associateddissolved gas (which are the two major types of wet natural gas), and total dry gas (wet gas adjusted for the removal of liquids at natural gas processing plants). In addition, reserve estimates for two types of natural gas liquids, lease condensate and natural gas plant liquids, are presented. The estimates are based upon data obtained from two annual EIA surveys: Form EIA23, Annual Survey of Domestic Oil and Gas Reserves and Form EIA64A, Annual Report of the Origin of Natural Gas Liquids Production. Also included is information on crude oil, natural gas, and lease condensate reserves in nonproducing reservoirs. A discussion of notable oil and gas exploration and development activities during 2007 is provided.
