Energy Production - Crude Oil (IEA)

Energy production comprises crude oil, natural gas liquids, refinery feedstocks, and additives as well as other hydrocarbons such as synthetic oil, mineral oils extracted from bituminous minerals (in the row production) and oils from coal and natural gas liquefaction (in the row liquefaction). Production is calculated after removal of impurities (e.g. sulphur from natural gas). A TOE is defined as 41.868 gigajoules or 10 Exp 7 kilocalories. One terawatt-hour = 0.086 MTOE.
