HOUSTON, July 9 -- Gulf Indonesia Resources Ltd., Jakarta, said its third and fourth wells on the Ketapang production-sharing contract area off East Java found hydrocarbons.
Jenggolo-1 tested at 3,600 b/d of oil from a 7/8-in. choke from perforations between 6,272 and 6,300 ft. A second test from perforations between 5,806 and 5,854 ft flowed 5 MMcfd of gas through a 1-in. choke. A third, between 4,780 and 4,804 ft, flowed 4 MMcfd through a 1/2-in. choke.
Payang-1 well flowed 17 MMcfd of gas through a 1-in. choke from perforations between 4,822 and 4,854 ft.
The first well in the four-well drilling program on Ketapang had gas shows and minor oil shows, but was not tested. The second, Bukit Tua-1, flowed at a combined rate of 7,250 b/d from two tests (OGJ Online, Mar. 27, 2001). Two shallower zones in the Bukit Tua-1 well flowed a combined 6 MMcfd of gas.
"Jenggolo confirms the productivity of the Kujung zone that tested oil at Bukit Tua, 16 km to the east, and the gas discovered during this drilling campaign could be sold into the growing gas market in East Java," said Cliff Zeliff, vice-president of exploration for Gulf Indonesia. "To evaluate the areal extent and magnitude of these discoveries, the partnership is now discussing a work program that includes a 3D seismic program over Bukit Tua-Jenggolo to be followed by further appraisal drilling in 2002."
Gulf Indonesia is contract operator of Ketapang and owns 50%. Its partner is Petronas Carigali Overseas Sdn. Bhd., which owns the other half.
Gulf Canada Resources Ltd., Calgary, owns 72% of Gulf Indonesia. Conoco Inc. has offered to buy Gulf Canada for $4.3 billion in cash (OGJ Online, May 29, 2001).
