Reservoir Simulation of CO2 Storage Using Compositional Flow Model for Geological Formations in Frio Field and Precaspian Basin

CO2 storage is a greenhouse gas mitigation instrument for many countries. In this paper, we investigate the possibility of in region Precaspian basin using compositional flow model that was verified by data Frio pilot project, USA. We use local grid refinement commercial reservoir simulator. simulation Pilot have achieved good history matching well pressure. Different scenarios were tested, and post-injection migration shown both case studies. The long-term shows potential amount trapped residual dissolved trapping mechanisms basin. performed uncertainty study covered model’s parameters resulting P10, P50 P90 cases terms CO2.
