A STUDY OF PRODUCTION OPTIMIZATION USING PROSPER

The production optimization of oil and gas wells using computerized well model has become a successful technique contributing towards the better efficiency and higher production of many wells. Well modeling using PROSPER, one of components of the Integrated Production Modeling (IPM) was implemented in Field X which is located in Peninsular Malaysia. The model carries all the properties of the well with detailed description of the reservoir and vertical lift performance. The process includes four phases. First phase was building well model by using PVT, IPR, surface and equipment data. Second phase was constructing well matching based on the monthly well test data. This helps to ensure that the model is well calibrated and constructed. Third phase was performing well analysis based on the well matching results. Well analysis can be performed by evaluating each components of the producing well. Often this procedure will identify possible problems occurred in the production components which restricting flow and causing the well to produce in a manner that the maximum potential rate not achieved. Overall, this production optimization technique permits engineer to come out with some modifications and suggestions which is expected to increase the production
