Abstract
The Lakat Formation of Central Sumatra field is a mature field that has been produced since 1970, and in 2018 the recovery factor has reach of 25.9%. In order to increase the recovery factor, hence the infill well scenario will be executed. Determination of the location of infill wells was carried out using the Decline Curve Analysis (DCA) Sectorization Method, due to in this field there is no SCAL and PVT data. The DCA sectorization method uses statistical analysis based on HCPV and permeability value. Determination of the infill wells coordinate is based on an overlay map of the three HCPV sectors, are current, permeability, and cumulative production. This method divided the formation into good, medium, and poor classes. The infill well scenario is done in good and medium classes. The development of the Lakat formation with infill The initial production rate of each infill well is determined by drawing a trendline on a combination of peak production, pressure, transmissibility, productivity index and time. The results of the analysis in the Lakat formation obtained in the good sector the exponential curve with decline rate of 7.3% has remaining reserve about 56 Mbbl. Whereas the medium sector by harmonic curve with decline rate 9.4% has remaining reserve about 71 Mbbl. The development of Lakat formation with 8 infill wells, including 6 locations in the good sector with an average initial production rate of 68 bbl/day, and 2 locations in the medium sector with an average initial production rate of 59 bbl/day. Based on the development scenario results in the Lakat layer of the Central Sumatra Field has obtained of oil production of 6479 MSTB and recovery factor of 36.1%.
