Fuel Gas Boosting

Project Description

To reduce flaring of associated gases during production at the Vakhitovskoe oilfield, TNK-BP (nowadays Rosneft OSJC) has implemented an emission reduction project. Under this project BPC Energy has supplied in total six Opra gas turbines using untreated wellhead gas as fuel gas. The gathered wellhead gas was sent to the fuel gas boosters, increasing the fuel gas pressure to the level required by the gas turbines.

CSH has supplied in total four skid mounted, electric driven screw compressors to boost the wellhead gas to a pressure of 12 bar(g).
