The economic gas plateau rate is a plateau rate that provide most benefit to contractor, evaluating from recovery factor in the end of contract and also giving <br /> <br /> <br /> high rate of return, while government get enough amount potential gas recovery that give maximum profit to them. According to this fact, formed a hypothesis that <br /> <br /> <br /> the most economical plateau rate is the corresponding rate to the meeting point of the plot Contractor Recovery Factor (CRF) and Government Recovery Factor <br /> <br /> <br /> (GRF) to Rate of Return (ROR). This thesis gives a brief description of determination of economic plateau gas flow rate that is built based on this hypothesis. <br /> <br /> <br /> Sensitivity test is also done to see the influence of each parameter on economic plateau gas flow rate. The test result yield that residual gas saturation is the most sensitive parameter for economical plateau gas flow rate. The rate of change of residual gas saturation in flow rate is 10.0608, while permeability and gas relative permeability respectively 8.4997 and 7.9656. Furthermore, a correlation established using Least-Square method to show the relationship between economic plateau gas flow rate with parameters: permeability, residual gas saturation, and gas relative permeability. The accuracy of the correlation is good with error less than 10%. The correlation is valid for permeability up to 150 mD and 0.5 residual gas saturation.
