Natural gas has been the life line of the commercial energy resource of Bangladesh for several decades. It is the primary option to satisfy the environmentally clean energy, whereas coal is a dirty energy source and oil creates an unhealthy environment. In petroleum industry production optimization is one of the most important task for production engineer to meet the increasing demand for natural gas among the nation. If the production rate is not optimized then it is not either economic or it raises bad effects to the reservoir performance. This study aims at forecasting the optimized production rate of Meghna Gas Field. The major motive is to improve the IPR and VFP curve form the former one. The general conventional process of optimizing the production rate by cross plotting improved Inflow Performance Curve and Vertical Flowing Performance Curve in a graph paper. The two curves intercept in a single point which is considered as the best production rate against the respective wellbore flowing pressure.
