註釋This paper addresses the prospects for conventionally produced petroleum. This includes crude oil, natural gas liquids, and natural gas produced from accumulations where some commercial production can occur without injection or fracturing. It excludes petroleum liquids produced from tar sands, oil shale, coal, and biomass. It excludes natural gas produced from coal, shales, tight (microdarcy permeability) sandstones, and landfills. In some cases, the dividing line between the conventional and nonconventional is fuzzy, for example, between conventionally produced heavy crude oil and some tar sands or between natural gas production from low and very low permeability sandstones. These, however, are rare enough to make the distinction a workable one in practice.
