A study on the miscibility mechanisms and patterns of high CO2 content associated gas reinjection

Abstract To investigate the enhanced oil recovery mechanisms during the reinjection of CO2-rich associated gas, analyse the miscibility behaviour between associated gas and crude oil, and provide guidance for increasing oil recovery in field development, in this study, gas injection expansion experi...
