Abstract

Condensate accumulation is a major problem encountered in most of the gas condensate reservoir. During production, the pressure decline causes the formation of condensate that reduces well productivity. Therefore, this study aims to improve well productivity by using various type of gas injection. At the same time, different injection scheme such as distance between injector and producer and injection rate also have been analyzed. Compositional simulator is employed to simulate the studies on hypothetical gas condensate reservoir model. By injecting rarely used propane, it manages to increase the recovery up to 19.8% compared to other conventional injectants. Considering the availability of propane, the efficiency of gas-gas flooding (propane+nitrogen) and gas-solvent flooding (propane+methanol) flooding has been studied where gas-solvent flooding shows 21% of recovery which is higher than pure propane and conventional gas injection. Well distance of the factor of 6 with the injection rate of 8000 MSCF/d shows 19.5% of condensate recovery increment which is the highest compared to other injection scheme studied. Based on the results, propane gas should be considered heavily in condensate removal application as it improves condensate recovery and well productivity at the same time. In general, this study confirmed that the injection component and injection scheme plays an important role in enhancing condensate recovery in the
