HOUSTON, May 21 -- Unocal Rapak Ltd., subsidiary of Unocal Corp., El Segundo, Calif., has drilled its fifth successful well in deepwater Ranggas oil field in the southern part of the Rapak production-sharing contract off East Kalimantan, Indonesia.
The Ranggas-5 appraisal well was drilled in 5,412 ft of water to 11,858 ft TVD, encountering 203 ft of net oil pay and 618 ft of net gas pay.
The well is 1.5 miles north of the Ranggas-1 discovery well and 0.7 mile south of the Ranggas-4 well, which was recently tested at 8,158 b/d of oil and 6.4 MMcfd of natural gas from a single interval.
"The [Ranggas-5] well penetrated more net pay than any other well in Unocal Indonesia's long history," said Brian Marcotte, president of Unocal Indonesia Co. "Because of our successful appraisal drilling program, we have initiated engineering and development studies for the field."
Unocal Rapak is operator of the Rapak PSC, holding an 80% working interest, while Lasmo Rapak Ltd., a subsidiary of ENI SPA, holds 20%.
