In the last 5 years, the production per day in Indonesia has been naturally dropped below 1 MBOPD. The production effort has a limitation for changing the natural drop maximum 10 %. Meanwhile the replacement reserves by exploration discoveries did not have a significant result. Those fact pushed of Indonesian Government through BPMIGAS to conduct a Resources Management in Indonesia.
In general the resources management will discuss historical assessment (reserves management), current assessment (sub-commercial resources) and future assessment of the resources (resources management). Reserves management that has being done is defining the production fields which has potential for small exploration to increase the production rate of the field. Sub-commercial resources management is defining the exploration discoveries in the last ten years which has not being developed because economic reason when it's discovered. Resources management is defining from prospect & lead data then classified into four category i.e : drillable, need more evaluation, need more seismic, and on pending status, than after that are being calculated to get a prospect ranking. Final step of this resources management are integrating the results and discuss with block operators to create exploration strategy. This paper will only discuss about resources management on mature basin in Sumatera Island, Indonesia, which of four producing basin (North Sumatera Basin, Central Sumatera Basin, South Sumatera Basin and Sunda Basin). The historical assessment of those basins has found more than 42.6 BBOE which consist of more than 400 fields. Current assessment of Sumatra's basin has found more than 20 discoveries, and resources management has indicating more than 100 prospect & lead are ready to drill. All those data are being communicated and discuss with the block operators in Sumatra Island to generate a exploration strategy.
