Methane emission by petroleum industry in Western Siberia according to satellite observations

We present a technology and results of estimation of methane emission by oil industry enterprises in Western Siberia in 2019. The experimental basis of the work is the results of satellite observations. It is established that methane emission from combustion of associated petroleum gas in flare units in Western Siberia is about 0.3 Tg. This result is based on the previously obtained information on the characteristics of flare units according to VIIRS/Suomi-NPP data. This information also allowed us to determine the locations of the petroleum industry sites in Western Siberia. TROPOMI Sentinel–5 Precurcor and NCEP-DOE AMIP-II Reanalysis (R-2) data were used to estimate methane emission by the oil industry enterprises in Western Siberia, which can reach 3.1 Tg.
