Summary: | X field is gas field with 12.6% recovery factor. New field development contract has been agreed for 15 years with buyer availability option in 3 years,5 years, or 10 years plateau rate time. Goal of study is to determine most economical plateau rate and plateau rate time using reservoir simulation to predict field production in which intergrated with designing production facility based on gas characteristics and production rate each scenario and last is economic calculation refer to development scenario.
In place matching and history matching process resulting that reservoir simulation model is representative enough. Field development conducted by opening 7 layer through 4 wells workover job. From reservoir simulation results, target of 3 years plateau rate time is reached by 8.3 MMSCFD plateau rate with 29.54% recovery factor,while the 5 years target is reached by 5.55 MMSCFD plateau rate with 29.34% recovery factor and the 10 years target is reached by 3.05 MMSCFD plateau rate with 28.99% recovery factor.Production facility design requires the gas separation, gas sweetening, gas dehydration dan HC dew point control systems. Based on economic analysis, the scenario of 3 years plateau rate time is the most economical scenario. |
