Abstract

Oil production decline in mature fields often occurs due to the reduction of natural reservoir pressure, leading to limited oil recovery. To address this issue, the application of Enhanced Oil Recovery (EOR) techniques using CO₂ injection and Alkaline-Surfactant-Polymer (ASP) is explored. This study aims to evaluate the application of the ASP Alternating CO₂ Flooding method in Field X using reservoir simulation with CMG-STARS software. Simulations were conducted with varying CO₂ and ASP injection ratios and slug size to identify that yields the best recovery factor (RF). The results show that the alternating use of ASP and CO₂ (ASPAG) significantly improves the recovery factor. The scenario with a 1:2 ratio and a slug size of 0.6 produced the largest RF increase of up to 29,3%, indicating that the combination of CO₂ and ASP injection in this ratio can enhance oil recovery efficiency more optimally.
