Description
Summary:There were many old oil wells in Indonesia, besides that, it was relatively difficult to get new oil reserves, so that oil production decreases. If no new reserves were found or additional new supplies were available, slow or fast oil production would run out. One alternative that was being developed to increase petroleum production was through Enhanced Oil Recovery (EOR) technology using surfactant injection. Surfactant Sodium Ligno Sulfonate (SLS) was a surface active agent that could reduce the interface tension between oil and water. The aim of this study was to increase the usefulness of SLS surfactants from biomass waste which was abundant in production in Indonesia, especially to assess the best injection pressure and sodium lignosulfonate characterization. This research was carried out by varying the pressure (0.5; 1.0; 1.5; 2.0 kg / cm2, with surfactant concentrations in 5,000 ppm 0.5% synthetic brine of NaCl. There were 3 stages of research, namely making black liquor sodium lignosulfonate surfactant, surfactant characterization stage and core flooding test. The results achieved from this study that the pressure variations in the core flooding test could affect the yield of oil obtained. The pressure that produced the best oil yield was a pressure of 0.5 kg / cm2. The pressure on the injection of SLS surfactant to the core flooding affected the rate oil flow at yield, this was the initial hydrodynamic study of this research.
