Alpha field gas is gas field that located in Arafura Sea, North Bonaparte Basin. This field has not been produced yet, which has initial reserve 10.68 TCF P1, 3.48 TCF P2, and 0.84 TCF P3. Project of this field will be developing within 24 years of production. The purpose of this study is to determine gas plateau rate that provide best economic scenario with nodal analysis and P/Z method to forecast the production. surface facilities design of this field based on gas fluid characteristic and production rate of each scenario. Each development scenario has economic calculation. <br /> <br /> Reservoir of Alpha Field located at Plover Formation with dominant lithology sandstone. Plover Formation has 8 zone, which is zone A-E with sandstone diverse content. This field has fluid expansion with a small contain of pv compressibility driving mechanism. The result of small pv compressibility indicate that small amount of rock compressibility change. Therefore, production forecasting with nodal analysis method and p/z method has high degree of certainty. There were 3 fields development scenario, case 1 has 858 MMSCFD plateau rate with 70.38% recovery factor, case 2 has 868.5 MMSCFD plateau rate with 71.24% recovery factor, and case 3 has 868 MMSCFD plateau rate with 71.2% recovery factor. Production facility design requires the gas separation, gas sweetening, gas dehydration, and HC dew point control systems. Based on economic analysis, case 2 is the most economical scenario.
