Bekapai is a mature oil and gas field located in the offshore Mahakam Delta, Indonesia. The hydrocarbons are accumulated in complex multilayered reservoirs. Ten platforms were constructed to accommodate the oil production coming from 74 wells drilled between 1974 and 1996. The production started in 1974 with peak production at~60,000 BOPD in 1978, followed by a period of decline until it reached its lowest point at 1,000 BOPD in 2007.A field re-development project, so-called Phase 1 initiated in 2008, had increased the production to 10,000 BOPD and 46 MMSCFD by the end of 2013. It consisted of 9 development wells. Following this successful project, a new 3D OBC seismic was acquired and further development plan, Phase 2, initiated, consisting of 10 development wells and gas production facility debottlenecking. Two wells have been drilled in 2014 and contribute in stabilizing the production of 2014 at 11,500 BOPD and 38 MMSCFD, the highest oil production of the past 25 years. The gas production decreases as a consequence to field production facility limitation. It was shelved due to priority of oil development. However, it is expected to increase to 100 MMSCFD in 2015 after the debottlenecking. In parallel, idle wells reactivation to access the shallow gas resources is also reviewed. Besides contributing to gas export, the gas is also used as artificial lift to revitalize the oil wells.This paper demonstrates the main elements of the redevelopment: evolution of the geological model achieved through seismic and petrophysical data, production management in a complex production system and various optimizations at the production network in order to unlock the production capacity limit through debottlenecking projects and chemical injection at the export line. A continuous effort in even further redeveloping the field is also shown through Phase 2, the objective of which will be chasing the attic oil, blowing down the gas-cap, and double the gas production.
