Abstract

The optimal location of drilling the wells. in the oil and surrounding application has caused a significant economical impact on the reservoir management. The wells location issue in a productive formation is a vital aspect in order to have an effective . field development. However, the determination of the optimal wells location in the specific geographical locations is a challenging matter since it depends on the geological and the fluid properties, reservoir characteristics and as well as on the economic parameters. Hence, reservoir simulation is recognized as one of the most . reliable tools for defining the optimum strategy of production. Nevertheless, using the simulation approach in doing the forecasting bears the risk of uncertainty in the input data. Due to the reservoir inhomogeneity and the uncertainty in the reservoir description, solution to the problem is impossible at the intuitive level. Using the conventional approach to define the number of production wells and its locations is a costly trial and error process as the outcome is fully depends on the ability of the reservoir engineer to understand the reservoir behavior and its operational limits. Thus, an alternative approach in optimizing the well location which is by determining the high productivity zone within the reservoir where the hydrocarbon production is expected to reach the maximum field production. It is performed by evaluating each. of the possible well position at different locations and defining the sensitivity of several reservoir properties which will have the significant impact to the optimum well placement. The. studied was carried out on an actual Malaysia reservoir model which is the Gelama Merah field located in offshore Sabab. By utilizing the Eclipse lOO - A black oil model simulator software, several studies have been made and the predicted values of production were significantly promising. Furthermore, it was found that the. optimal well production duration is a function of well spacing with respect to the number of production well drilled. Apart from that, changing of oil saturation (So) will always contribute to the high impact for the optimal well placement and oil productivity. Hence, the method proposed could be one of the useful tool to assist the progress in the decision making for the field development and strikes towards the optimal and effective hydrocarbon recovery.
