| Summary: | his study analyzes the rheological properties of polymer under various shear rate, polymer concentration and molecular weight, temperature, salinity and divalent for potential Enhanced Oil Recovery (EOR) application. The polymers used were Xantham Gum (XG), Guar Gu m (GG), Arabic Gum (AG), Polyvinylpyrrolidone (PP) and Partial Hydrolyzed Polyacrylamide (HPAM). Fann, Gr ace Instrument and Brookfield viscometers were employed for viscosity measurement. The result s recommended GG, AG and PP based on their shear thickening behaviour, XG and HPAM for their high molecular weight, PP and AG for their ability to withstand high temperature and salinity c ondition, and GG, PP and AG in high divalent concentration.
