EOS Fluid Characterization Modeling for Miscible CO2 Flooding in Volve Field

A18 EOS Fluid Characterization Modeling for Miscible CO2 Flooding in Volve Field T. Yang* (Statoil ASA) & G. Byberg (Statoil ASA) SUMMARY Due to increasing environmental concerns with CO2 and high demands of injection gas for improving oil recovery CO2 injection for IOR process is attracting more attentions recently in many fields world wide. Besides other important factors (e.g. reservoir properties production designs) EOS fluid characterization plays a critical role for the complex miscible displacement process. This paper describes the procedures to accurate build an EOS fluid characterization to match all related gas injection experimental data (including swelling multi-contact and
