The idea of integrated development is triggered by the result of individual development plan studies of MJ and MX fields that show pessimistic results due to limited volume of resources, distances from existing facilities, high total CAPEX, low oil prices and characteristics of reservoir fluids. The characteristic of MJ’s fluid is waxy and has high pour point that will cause flow assurance and back pressure issues. In addition, MJ and MX fields are relatively far from the existing facilities, these are the problems that will lead to high CAPEX for each individual development. This paper will present the integrated sequential development plan which will cover comprehensive analysis of subsurface, conceptual facility designs and economic aspects of integrated development. The development scenario of this integrated project will start with producing MX by three horizontal wells and recover 5.6 mmbo oil reserve. Then after three years, MJ will start producing through three deviated wells and recover 4 mmbo oil and 6.5 bcf gas reserve. The form of integrated development is applied by sending water production from MX to MJ field through main water line. It will be effectively utilized after MX’s water production reach 4000 bwpd after three years of MX’s production. This method will encounter the flow assurance and back pressure issues in MJ field, thus will eliminate the establishment of heater plant and insulated pipeline for MJ platform. Furthermore, this method will shorten the material and pipeline installation period for MX field. At the end, this integrated scheme will decrease total CAPEX for field development. Eventually, we will successful to reduce the total CAPEX by 35%, achieve positive NPV, increasing IRR by 21% and five years faster payback period. Moreover, the economic indicators still show positive results at 40$/barrel oil and 7$/mmbtu gas compared to individual development.
