The chart shows forecast of greenhouse gas (GHG) emissions from oil exploration, production, transportation and refining of oil by GHG. CO2 and CH4 are mostly emitted by petroleum systems. Emissions of other gases is negligible.
In recent years industry focused on reduction of methane emissions from different fugitive leaks, venting from pneumatic devices, facilities, compressors, and well completions.
CO2 and CH4 emissions also come from flaring, produced water, drilling mug degassing, chemical injection pump and other equipment normal operation and malfunction.
