Material Balance Study of Gas Reservoirs by Flowing Well Method: A Case Study of Bakhrabad Gas Field

Abstract Due to critical production-demand situation, proper pressure survey can not be conducted on a regular basis in the gas fields of Bangladesh. Shutting in the wells for pressure survey is also very expensive for the gas production companies. Flowing well method provides an opportunity for updating the reserves without interrupting the production. In recent years, pressures of different sands of Bakhrabad Gas Field have been declining sharply and it is believed that the field would be exhausted very shortly. Therefore, Bakhrabad Gas Field is a perfect candidate for applying this new method to estimate the gas reserve and verify it by the actual reservoir performance. Flowing well method of estimating the gas reserve is based on the assumptions that…
