Overpressure or exclusive drawdown is one of the most common causes of failure in onshore and offshore industries. Exclusive drawdown refers to the excessive production occurred in the reservoir due to large difference of reservoir pressure and flowing bottom hole pressure. It is difficult to predict its occurrence as well as to prevent it. One of the solution is by having a good information about the well regarding the inflow pressure, outflow pressure, the expected production rate and the fluid properties of the reservoir. There are a lot of harm consequences that may happen due to exclusive drawdown that result in production decline. Thus, the projective objective is to do numerical simulation analysis as the effect of having exlusice/excessive productivity to the reservoir and petrophysical properties. The analysis will be focusing on the pressure drawdown itself. Scope of study involved conducting the simulation of software include the visual inspection and well test result by using Pansystem Software to measure the production rate and inflow performance relationship by making comparison of having optimum drawdown and exclusive drawdown. This study is very important to be conducted to ensure the reservoir can last long and meet the expected lifetime.
