In this research, the phase-behavioral test with observation of SLS surfactant of bagasse of three kinds of crude oil is light oil (42°API), intermediate oil (25°API) and heavy oil (18°API). From the results of these observations, it turns out SLS surfactant bagasse to form emulsion on light oil. The surfactant composition of SLS bagasse which mostly forming the middle phase emulsion (microemulsion) which is 10% is in the proportion of 10.000 ppm -1.5% composition while the surfactant composition of SLS is the smallest emulsion the middle phase (0%) is in the proportion of the composition of 20,000 ppm 4.5% and 40,000 ppm 4%. The highest injection result occurred in the surfactant composition of 1.5% with salinity 80.000 ppm which resulted in addition of recovery factor of 10.71%. While the lowest SLS surfactant injection occurred at a surfactant composition of 4.5% at salinity 20,000 ppm which only gained 1.05% recovery factor. Thus, it can be concluded that the recovery factor in the EOR process is determined by the formation of a sufficient middle phases emulsion at a small concentration of SLS surfactant.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Light oil,Oil recoveries,Phase emulsions,Recovery factors,Small concentration,Surfactant composition,Surfactant concentrations[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research was facilitated by the Research Consortium OGRINDO at ITB, Trisakti University, and the Indonesian Directorate General of Higher Education Decentralization Fund for PUPT Fund 2017 ITB – Dikti.
