Abstract

A core flooding experiment was carried out to simulate an Enhanced Gas Recovery (EGR) process to inject supercritical Carbon Dioxide (SCO₂) into a core sample saturated with methane (CH₄). This was done to investigate the flow behaviour of the injected SCO₂ at the flow conditions when the injection orientation was switched from horizontal to vertical during the CH₄ displacement. From the results, it was found that gravity has significant effects on the flow behaviour of SCO₂ at lower flowrates; more pronounced is the seemingly lower permeability in the horizontal orientation compared with the vertical orientation. So the choice of the injection pattern or direction during EGR by SCO₂ injection for the purpose of additional recovery of CH₄ and subsequent sequestration of the injected CO₂ should be made in conjunction with the determination of optimum injection rate for efficient injectivity.
