Efforts to increase production from an oil and gas field require a holistic approach that integrates various components of production (reservoirs, wells and surface production network) as a unified whole production system. In the oil and gas industry this approach is also known as integrated production modeling. Changes occurring within the reservoir can be evaluated for their impact on well production conditions and pipeline network facility, and vice versa. Thus, the applied field development strategy will consider existing restrictions on surface network facilities and produce realistic results. In this study, an integrated production model was developed and implemented for a matures old oil field that has been operating for more than forty years. Based on the existing production conditions in the field, an integrated model is used to evaluate potential development strategies applicable to the field that emphasize on surface asset utilization. In addition, fluid flow conditions within the production network facility are also evaluated to determine potential problems that may occur in the network based on existing scenarios. The study results suggest that production increases in a relatively short time can be achieved by replacing the current ESP pumps with pumps having larger capacities, considering the production potential of wells in the field. In addition, it is observed that increasing field production rate does not necessarily reduce the potential of fluid flow problem at the surface network from happening. As the study suggests, it thus may be necessary to replace the existing mainline pipe sizes with smaller one in such a way that potential bottlenecking problem to occur can be further minimized.
