Abstract

With notion to the potential use of cyclical CO2 injection as a follow-up post-CHOPS (Cold Heavy Oil Production with Sand) EOR option, a comprehensive core-to-field scale study was performed to investigate the non-equilibrium CO2 behavior. PVT lab measurements of both CO2 injection and depletion tests were performed and modeled under highly controlled conditions and at different temperatures to obtain equilibrium properties. To address the kinetics of the non-equilibrium process, a 1.5-m multiple pressure-port core holder was designed to measure the differential pressure in the various sections of the sand-pack during CO2 depletion tests. Oil and gas volumes and the signature of pressures along the core holder length were recorded at each trial.
