Abstract
Surfactant injection is one of the EOR methods used to increase oil recovery. Using of surfactants is intended to reduce the interface tension between oil and water. The types of surfactants commonly used are oil-based surfactants, such as petroleum sulfonate. This condition causes the price of surfactants very dependent on oil prices. As efficient alternative, research on plant-based surfactants sourced from nature is being developed. Like the type of surfactant that will be used in this study is Sodium Lignosulfonate (NaLS) sourced from bagasse waste. The purpose of this study is to add reference of the characteristics of the NaLS surfactant to be used optimally. The screenings in this experiment were Aqueous Stability test, phase behavior test, and IFT test on 1.5% NaLS concentration and high salinity 70,000 ppm Nacl. The results of aqueous stability test is transparent, the results of phase behavior test is middle phase emulsion with an emulsion percent of 8.75%, and the results of IFT test obtained value of 1.98 mN/m. Based on these results, surfactants meet the screening parameters so can proceed to the injection stage for determine the value of recovery factor. Results of recovery factor for bagasse waste NaLS surfactant injection is 4.4%.
