HOUSTON, Apr. 1 -- ConocoPhillips Indonesia, a subsidiary of ConocoPhillips, reported the successful test of its Suban-8 delineation well on the southwest flank of Suban natural gas field on the Corridor block production-sharing contract in South Sumatra, Indonesia.
The step-out well was spudded Oct. 3, 2002, and reached 3,147 m TD on Nov. 23. Suban-8 successfully tested a separate fault block adjacent to and southwest of Suban field. The well encountered a gross pay section more than 400 m thick, and tested at a maximum rate of 35 MMscfd of natural gas and 163 b/d of condensate through a 52/64-in. choke.
ConocoPhillips Indonesia evolved from then-Conoco Inc.'s purchase in 2001 of Gulf Canada Resources Ltd., which owned a 72% interest in the Jakarta-based consortium Gulf Indonesia Resources Ltd., the original discoverer of Suban field (OGJ Online, May 29, 2001). Former Gulf Indonesia Pres. and CEO Bill Fanagan said at the time: "Suban field has the potential to be 4 tcf or more in size, which could support additional gas sales of 550 MMcfd from the Corridor block over and above the current contracted amounts (OGJ Online, May 7, 2001)." ConocoPhillips Indonesia is continuing to appraise and develop the field.
Gas from Suban currently is sold to Pertamina for the Duri steamflood project operated by Caltex Petroleum Corp. in central Sumatra. The agreements call for 1.1 tcf of gas to be delivered over a period of 19 years in exchange for Duri crude oil at 8 Mcf/bbl. Gas quantities delivered are expected to reach 180 MMcfd by the middle of this year to offset a planned decline of 245 MMcfd in the original agreement with Caltex (OGJ Online, Dec. 22, 2001).
ConocoPhillips serves as operator of Suban field and holds a 54% ownership interest; Talisman (Corridor) Ltd., a wholly owned, indirect subsidiary of Talisman Energy Inc., has 35%; and Pertamina 10%.
