¹Represents lower 48 onshore and offshore supplies.
²Marketed production (wet) minus extraction losses.
³Gas which occurs in crude oil reserves either as free gas (associated) or as gas in solution with crude oil (dissolved).
⁴Synthetic natural gas, propane air, coke oven gas, refinery gas, biomass gas, air injected for Btu stabilization, and manufactured gas commingled and distributed with natural gas.
⁵Includes consumption by cogenerators.
⁶Includes all electric power generators except cogenerators, which produce electricity and other useful thermal energy. Includes small power producers and exempt wholesale generators.
⁷Represents natural gas used in the field gathering and processing plant machinery.
⁸Compressed natural gas used as vehicle fuel.
⁹Balancing item. Natural gas lost as a result of converting flow data measured at varying temperatures and pressures to a standard temperature and pressure and the merger of different data reporting systems which vary in scope, format, definition, and respondent type.
