Abstract: 

ONE OF THE IMPORTANT METHODS OF ENHANCED OIL RECOVERY IS WATER INJECTION INTO OIL RESERVOIRS. SPONTANEOUS IMBIBITION OF WATER INTO THE MATRIX OF FRACTURED RESERVOIRS, EXPEL THE OIL TO THE FRACTURE SYSTEM AND FINALLY PRODUCTION WELLS. IN FRACTURED CARBONATE RESERVOIRS DUE TO LOW OR NEGATIVE CAPILLARY PRESSURE, WATER SPONTANEOUS IMBIBITION INTO MATRIXES WILL NOT OCCUR AND WATER INJECTION PROCESS WILL NOT EFFECTIVE. IN SUCH RESERVOIRS THE SUITABLE METHOD FOR HIGH OIL RECOVERY IS A METHOD THAT CAUSES OIL SWELLING, OIL VISCOSITY REDUCTION, REDUCING INTERFACIAL TENSION AND WETTABILITY ALTERATION. IN FRACTURED CARBONATE RESERVOIRS, HIGH OIL RECOVERY OBTAIN AFTER CHANGE ROCK WETTABILITY FROM OIL WET TO WATER WET AND DUE TO WATER SPONTANEOUS IMBIBITION’S. THEREFORE USE OF THE METHOD POLYMER SURFACTANT FLOODING ALTHOUGH IT'S EXPENSIVE BUT IS VERY EFFICIENT FOR SUCH RESERVOIRS. IN THIS PROCESS SURFACTANT REDUCE SURFACE TENSION AND CHANGE ROCK WETTABILITY AND POLYMER INCREASE VISCOSITY AND CONTROLS MOBILITY RATIO. IN THIS PROJECT POLYMER SURFACTANT FLOODING SIMULATION IN ONE OF IRANIAN FRACTURED RESERVOIRS BY ECLIPSE SOFTWARE IS DONE AND OIL RECOVERY IS STUDY BY CHANGING KEY PARAMETERS SUCH AS FLOW, SURFACTANT AND POLYMER CONCENTRATION, SLUG SIZE, VOLUME OF INJECTION, ETC., AND OPTIMAL SCENARIOS AND VALUES ARE SPECIFIED. AND ENHANCED OIL RECOVERY UP TO 10.6% WAS ACHIEVED COMPARED TO NATURAL DEPLETION.
