Abstract

Production optimization is very important since it is a method to improve the production with increase the production and reduce the operating cost. In this project, the scope study would be to investigate the best case of the surface network model that will use to increase the production in the field. Economy evaluation for each case in the model should be done in order to determine the profitable project which will give the optimum production and reasonable cost. Cases that can be done in this project would be the field which will produce naturally and with support by artificial lift such as gas lift. The area that will do for project is Pentagon cluster. It is located in the MS-325 block. In this cluster, it will divide them into 5 fields which are field A, field B, field C, field D and field E. Currently all the wells is producing naturally which means that it should be produce without any artificial lift support and will considered as the base case. After integrate the surface network model for this cluster, the average annual production is for every year is about 2.350 MMSTB while the pressure at separator after make some sensitivity analysis is 877 psig. The problems that facing in this project is wells in field B where it has less annual production although the oil production that can recovered in this field is high . It is due to the insufficient pressure draw-down which is to produce the oil. It can be the characteristics of reservoir or well which is not good enough to produce the oil. Hence, optimization study should be done in order to determine the method which can increase the production. The optimization that will do in this project is use the gas lift support at all wells in field B as the method to improve the production. The gas lift rate that use from the sensitivity analysis is I 00 SCF /STB. Thus, the prediction production should be done for both cases in order to get the production forecast. From this prediction, it is easier to know the effect of gas lift in the field by looking the annual production and bottomhole pressure for pentagon cluster. Once integrate the model, economy evaluation should be done in order to know the economical of this project for both cases when the field is producing naturally or with support by gas lift. From the study, the cases that will consider in this project are the field which is producing naturally. It is because costs that use in to design the gas lift well are increasing than the cost that will get from the oil production.
