Abstract

 UPON DEPLETION, FALLING THE RESERVOIR PRESSURE BELOW THE DEW-POINT OF HYDROCARBON MIXTURE RESULTS IN LIQUID CONDENSATION AROUND THE WELLBORE. THIS LIQUID BARRIER CAUSES SEVERE REDUCTIONS IN GAS PRODUCTION RATES, THE PERMANENT LOSS OF A LARGE PORTION OF VOLATILE AND VALUABLE CONDENSATES, AND A WRONG ESTIMATION OF WELL DELIVERABILITY. IT IS BELIEVED THAT APPLYING THE GENERALIZED PSEUDO PRESSURE (GPP) METHOD LEADS TO MORE ACCURATE MODELING OF RESERVOIR PERFORMANCE. HENCE, USING A COMPOSITIONAL SIMULATOR, A SECTOR OF PAZANAN RESERVOIR (IN THE SOUTHWEST OF IRAN) IS MODELED WITH TWO DIFFERENT PERMEABILITIES: WITH THE AVERAGE PERMEABILITY OF 42 MD (ORIGINAL CASE) AND 0.1 MD (TIGHT CASE). THE RESULTS OBTAINED FROM SIMULATIONS DEMONSTRATE THAT THE GPP METHOD LEADS TO ACCEPTABLE RESULTS IN PERMEABLE CASE WHILE, IN TIGHT SYSTEM, IT UNDERESTIMATES THE WELL DELIVERABILITY. FURTHERMORE, SINCE GAS INJECTION/CYCLING IS THE MAIN RECOVERY PROCESS IN GAS CONDENSATE RESERVOIR, USING THE GPP METHOD, VARIOUS GAS INJECTION SCENARIOS IN THE RESERVOIR (ORIGINAL CASE) AT PRESSURES BELOW THE DEW POINT (MAXIMUM CONDENSATE APPEARANCE) ARE INVESTIGATED WHICH SHOWS THAT GAS CYCLING SCENARIO IS THE OPTIMUM SOLUTION.
