| Summary: | Decline Analysis is analysis with purposes to define production change of a well in certain period, construct the trend and then forecast it as well performance prediction. Fetkovich Method has been used as guideline to simulate gas/geothermal well production performance. It has been used widely and give an accurate model of production performance. But, there is a weakness in Fetkovich Method, which is it’s difficult to understand the change of parameter stabilization production coefficient and deliverability exponent with their correlation in wellbore or reservoir. Acuna and Pasaribu (2010) can handle this problem with anaylitical method through parameter of friction coefficient in wellbore and productivity index in reservoir. Basic concept of this method is based on derivation of mass rate equation to pressure loss that occur in wellbore and reservoir. |
