Abstract
Reserve estimation is the fundamental study in the field of petroleum engineering for economic analysis of a reservoir. If a considerable reserve of gas or oil is in place and the pressure is also high enough, then a reservoir can be considered economically viable to go on production. In the early life of the reservoir mainly during or just after exploration; volumetric calculation is the key to estimate reserve. However, it is sometimes invaluable to estimate reserve during production life of the reservoir. Considering this aspect, we have tried to exercise a graphical and reliable approach to estimate reserve. Production data, well data, fluid properties, formation properties were used for this task. It has been found that, total Gas Initially In Place (GIIP) is about 1.63 Tcf among which about 1.3 Tcf is recoverable with a recovery percentage of 80. In addition, total remaining reserve is calculated to be about 773 Bcf. All seven wells of Rashidpur Gas Field are estimated individually and summed up. The full study is a software approach and several typecurves have been exercised using a software "FEKETE F.A.S.T. RTATM. Since all the typecurves have showed approximately same result, we can be certain about the accuracy our estimation.
