Popis: The middle phase emulsion is the most important parameter in the compatibility test that determines the success of the surfactant in the Enhanced Oil Recovery (EOR) process. The purpose of this research was to observe the mid-phase emulsion formed on the use of Sodium Lignosulfonate (SLS) surfactant at various concentrations. One of the compatibility tests that will be used is the phase behavior test. Phase Behavior is carried out to determine whether SLS surfactant forms a middle phase emulsion when used in a crude oil. The method used in the phase behavior test is 2 mL of surfactant solution with a certain concentration mixed with 2 mL of crude oil which is inserted into a scaled test tube. Then the surfactant and crude oil solution in the test tube was shaken slowly. During the test, the test tube was placed in an oven at a temperature of 60° C for 21 days. The first observations were made during the first shaking process, then observed at 30 minutes, 60 minutes, 2 hours, 1 day, 2 days, 7 days, 14 days and 21 days. The formation water salinity were used at 40,000 ppm, 60,000 ppm and 80,000 ppm. From the results of this phase behavior test, the best mid-phase emulsion was formed at a surfactant concentration of 2.5% at 40,000 ppm of formation water salinity with an emulsion value of 11.3%. While the 60,000 ppm and 80,000 ppm formation water salinity formed the upper phase emulsion. From this research, it can be concluded that the formation of the middle phase emulsion of SLS surfactant bagasse in the intermediate crude oil was influenced by the salt content of the formation water used.
