Capillary pressure in reservoir influences either the gas rate, condensate rate, and water. Capillary pressure can help and interfere the production rate, depending on which the fluid will be produced. To determine the existence of capillary pressure effect on surface facilities design, at first, make reservoir model, and then matched the history data, sensitivity the displacement pressure (Pd), reduced CO2 and water content in gas. Reservoir was modeled as a beam with OGIP of 3,071 TSCF, consist of 8 layers and 4 wells. History matching of OGIP and production rate of gas, oil, and water were used to validate the reservoir. To determine the effect of capillary pressure, sensitivity was done by vary the displacement pressure (Pd) values of Pd are 0,02, 15, 20, 25, 35 psi. The longest time production gas was gained from the lowest Pd (0,02 psi) which 36 years, whereas the fastest time was gained from the highest Pd (35 psi) which 34,3 years. Oil production rate is same with the water, the highest production gain from the highest Pd. In this research, the vary of Pd <br /> <br /> <br /> ,gas rate still supplied the demand of constraint. <br /> <br /> <br /> The difference of water rate caused by difference of Pd/Swirr made the design of separator differs each other. The value of Pd/Swirr change of 1 made the <br /> <br /> <br /> volume change of 78,65 m3/5 minutes. Sensitivity result of TEG concentrations was the highest water content reached at the lowest concentration TEG (90%) produced water content of 49,5 lbH2O/MMSCF.
