... Abstract Alkali-Polymer (AP) flooding is currently piloted as an Enhanced Oil Recovery (EOR) method in Matzen field. Assessing the remaining oil saturation (Sor) both before and after AP is essential for determining the potential gain and effectiveness of this EOR method. We present...

... software RGMS, this enables comprehensive simulation of flow, thermal, and geomechanical processes during CO 2 sequestration. Buoyancy causes CO 2 to migrate upward, forming a CO 2 hydrate cap upon reaching the hydrate formation zone. Initially, the low saturation of the CO 2 hydrate cap allows limited...
