Abstract

Polymer injection is one method of Enhanced Oil Recovery (EOR), where the polymer is dissolved in water, usually the formation water. Hydrolyzed polyacrylamide (HPAM) polymer types are most commonly used. This study aims to investigate the effect of KYPAM HPAM polymer concentration and operating conditions upon the water injection in order to determine the optimal injection system. Viscosity of polyacrylamide solution was measured with a Brookfield viscometer. Variation in salinity is carried out by mixing formation water with distilled water, whereas for high salinity of formation water using evaporation method. Shear rate was varied in the range of 1-45 s-1, while solution temperature was varied in the range of 70 - 87°C , and the effect of H2S gas in the solution was conducted by saturating the solution using natural gas which has concentration of H2S as 100 ppm.The results show that the effect of salinity solution has the greatest influence on the decrease in viscosity of the solution when compared to the other factors. Decrease in viscosity was due to agglomeration process resulting precipitate of polyacrylamide in the form of vaterite and aragonite morphology. The result also show that an increase in shear rate resulting lower viscosity. The increase in temperature causes the viscosity of the solution decreases. Meanwhile, the presence of H2S in the solution reduces the viscosity of the solution due to chemical degradation.
