Abstract

Heavy oil production by CO2 gas foaming has been simulated with a function of depressurization pressure. The numerical simulation was carried out by using CMG-STARSTM and based on experimental physical properties of foamy oil such as foam swelling and apparent viscosity. The matching between the numerical simulations of heavy oil drainage and experimental measurements of foaming in Berea sandstone cores (Psat = 10 MPa at 50 °C) shows 31% of oil recovery after depressurization to atmospheric pressure. The behavior of heavy oil production and production scheme were proposed with assuming the CO2 gas dissolution zone. The effect of initial oil saturation and CO2 dissolution zone are the controlling factors of heavy oil production.
