Bima field, Indonesia: a sleeping giant
The recent Pertamina-ARCO Bima field discovery is 50 mi north of Jakarta, Indonesia, on the east flank of the Sunda basin. More than 1 billion bbl of oil are trapped in the Oligocene-Miocene Batu Raja Limestone within a productive area exceeding 25 mi/sup 2/. Additional oil is trapped in Oligocene Talang Akar sandstone reservoirs. The ZZZ-1 wildcat well drilled into the northern featheredge of the field in October 1974. A drill-stem test of the Batu Raja flowed 87 BOPD of heavy oil, and ZZZ-1 was plugged and abandoned as a noncommercial discovery. Postdrilling assessment suggested that the accumulation was stratigraphically controlled, and no delineation wells were drilled for 9 years. A second test of this trend was finally made in November 1983, to evaluate what was considered a separate Batu Raja closure updip from ZZZ-1. The ZU-1 well found a common oil-water contact with ZZZ-1 that suggested a structurally controlled giant field had been discovered. A series of step-out wells based on a seismic reinterpretation proved this hypothesis to be true. Phase one development drilling began in November 1985, and 57 wells should be completed within the next year. About 60 million bbl of reserves will be developed at an initial rate of about 50,000 BOPD. Phase two plans now in progress could develop an additional 40 million bbl of reserves.
