Abstract
As time elapses, diminishing oil reserves necessitate advanced techniques like tertiary oil recovery, specifically Enhanced Oil Recovery (EOR) methods. MES, a chemical compound derived from sodium bisulfite and methyl ester in palm oil, is the focus of this study. The objective is to evaluate the fluid stability of MES CoSurfactant in chemical injection, aiming to enhance oil production in reservoirs. In this laboratory investigation, Methyl Ethyl Sulfonate Surfactant (MES), combined with 96% ethanol (CoSurfactant) at concentrations ranging from 0.5% to 2.0%, and a salinity of 15,000 ppm, was used. Phase behavior tests assessed the emulsion stability produced by MES CoSurfactant. This process involved mixing the CoSurfactant solution with oil samples, shaking them, and incubating them at 60 degree C, observing emulsion formation over 21 days. Results indicate that CoSurfactant concentration influences emulsion formation at the specified salinity. Notably, a 0.75% CoSurfactant concentration produced the most stable upper emulsion phase, with a total emulsion of 2.50%, deemed the optimal surfactant. In the study involving light crude oil with 35 degree API and CoSurfactant, it successfully increased the total upper emulsion phase by 1%.
