Value Improving Practice VIPs for optimization of a marginal oil field development in ONWJ Indonesia

An oil and gas company in West Java Indonesia operates an oil field located on the Offshore North West Java (ONWJ) block. For maintaining production rate for oil and gas, its marginal oil field will be developed in the near future in order to meet management policy for national oil and gas demand. However, global oil prices have fallen sharply over the past year, leading to significant revenue shortfalls in the company, and having it sharply cut investments in exploration and production. The current production concept used contribute surface facility cost is high and it is not comparable with the reserve to be developed. The approach will be applied for ONWJ marginal field development is to cluster some fields in an integrated and developed in a sequential manner utilizing floating structure to support production. This paper describes the selection of floating structure technology using Analytical Hierarchy Process (AHP) method. This paper also presents an effective management tool Fuction Analysis System Technique (FAST) to be used as the rationale and integrated methodology for working through Value Improving Practices (VIPs) to improve fuction or cost floating structure system. Benefits of this approach are discussed including cost savings and future development flexibility. The cluster and sequential development approach with the utilization of floating structure described in the paper provide management with alternatives to current operation concept for ONWJ marginal field development.
