Abstract:
This study investigated different strategies to maximize the economics of gas and condensate production using results obatined from a compositional simulator. A simple reservoir model was constructed, and the actual initial reservoir conditions, fluid properties and composition were used in the model. Different production strategies, namely, production by natural depletion, production with gas cycling, and production with timely gas injection were simulated. The production rate, injection rate, and appropriate time to start gas injection were varied. Economic analyses were performed in order to evaluate each simulated scenario. The study concluded that production with gas cycling and timely gas injection is the optimal strategy in this gas-condensate production, and gas cycling can increase the recovery of hydrocarbon liquid, effectively.
