In the life of oil production can defined into three steps, primary, secondary, and tertiary. Primary recovery can include natural mechanisms such as rock expansion, gas cap, and solution gas, secondary recovery that use injection water or gas to maintenance reservoir pressure, enhanced oil recovery (tertiary recovery) that include injection special materials that is chemicals fluids, gas injection, and polymer injection. In this research use done Arabic gum as polymer flooding by using Gaberoun Water Leak & distillate water as soluble material and to make a comparison between two different water, use done three scenarios of the Arabic gum concentration, the first scenario Arabic gum with a concentration of 1%wt, the second scenario Arabic gum with concentration 3%wt and the third scenario with 5%wt. Imbibition test done used for this study by using Sandstone core samples aged in oil for a long time period reach about 3 weeks, the results of Recovery is obtained in oven temperature from 30℃ to 70℃. The oil recovery results are not very good as oil recovery by using Gaberoun Water Leak without any change on sandstone core samples, in this research reach to about 65, 62, and to 74 for 1wt%, 3wt% and 5wt% Arabic gum with Gaberoun Water Leak.
