JAKARTA (JP): The state-owned oil company Pertamina and its partner Saga Petroleum Indonesia Jambi have discovered natural gas and condensate at the Pulau Gading-1 (PGD) well, roughly 75 km southeast of Jambi, the capital of Jambi province.

Pertamina announced on Wednesday that the well was spudded on Nov. 14, 1995 and reached a final depth of 2,220 meters on Jan. 3, 1996.

Five tests were conducted in Basement, Weathered Basement, Talang Akar and Baturaja formations.

In the Weathered Basement testing period of 1975-1990, gas was discovered at the rate of 1.127 million cubic feet per day with a CO-2 content of approximately 20-21 percent.

The testing in the Baturaja formation, interval 1744-1768 meters, found gas which exits at the rate of 14.5 million cubic feet per day, and condensate at 472 barrels per day. A wellhead pressure of 1995 PSI and a CO-2 content of approximately 6.5-8.8 percent were measured.

A further test in the Baturaja formation at 1,703-1,726 meters resulted in the discovery of gas which exits at the rate of 17.7 million cubic feet, and condensate at 628.9 barrels per day, with a wellhead pressure of 1580 PSI and a CO-2 content of approximately 6.7-7.6 percent. (13)
