Abstract

 A KEY PARAMETER FOR APPLICATION OF POLYMER GELS IN WATER SHUTOFF TREATMENT IS THE ADSORPTION OF POLYMER GEL ONTO THE ROCK SURFACE. THIS PAPER DISCUSSES THE ADSORPTION PROPERTIES OF ONE OF THE SULFONATED COPOLYMERS. STATIC EXPERIMENTS WERE CONDUCTED TO EVALUATE THE ADSORPTION OF THE HYDROGEL AT DIFFERENT PRESSURES AND SOLID/LIQUID RATIOS. MOREOVER, POWDERED CARBONATE RESERVOIR ROCK WAS USED AS THE SOLID PHASE AND THE AVERAGE TEMPERATURE OF IRANIAN RESERVOIRS WERE SELECTED FOR THE EXPERIMENTS. THE RESULTS SHOWED THAT POLYMER GEL ADSORPTION INCREASED CONTINUOUSLY BY INCREASING THE PRESSURE WHILE THE POLYMER GEL ADSORPTION INCREASED BY INCREASING THE S/L RATIO AT A LIMITED RANGE (0.01 TO 0.035). ALSO THE MAXIMUM AMOUNT OF POLYMER GEL ADSORPTION WAS OBTAINED IN PRESSURES MORE THAN 3250 PSI AND S/L RATIO OF 0.03 TO 0.04.
