Gathering station is a part of production system in oil field therefore the location of gathering station has important influences to the performance of oil field production system (reservoir, well, flowline, and gathering station). Reservoir production performance is in dynamic condition as shown by the changing of pressure and fluid production, both influence to the capacity of fluid production that be treated and pressure loss along the flowline. The optimization of the component production system should be performed and in this thesis the optimization of gathering station location will be conducted. The criteria of gathering station location based on the highest cummulative oil <br /> <br /> <br /> production. The objective of this thesis is to define the optimum gathering station location based on optimization parameters such as plateau rate, well productivity, pressure loss in flowline, flowline length and diameter, separator pressure, and gathering station capacity. This optimization is conducted by developing model that consist of all component in oil field production system. The integrated model is representated by reservoir simulator (ECLIPSE), flowline network simulator (PIPESIM) and the interface FPT (Field Planning Tools) of ECLIPSE and PIPESIM. Using this integrated model, the location and number of production wells are determined, field plateau rate is calculated, configuration and dimension flowline are specified and then continued with gathering station location optimization for certain separator pressure. The optimization had been conducted by developing many scenarios and the best scenario that give highest cummulative oil production will be selected. The result shows that for different gathering station location will influence the cummulative oil production. The gathering station location which is not at the optimum location produced cummulative oil production of 15.91 MMSTB, otherwise for the optimum gathering station location produced cummulative oil production of 33.42 MMSTB at the separator pressure 200 psi.
