Gulf Indonesia Resources Ltd. reported its Suban-4 delineation well tested at the highest flow rate of any it has drilled in Indonesia�80 MMcfd of gas and 420 b/d of condensate from three perforated sections.

Production from the three sections�limestone, sandstone, and pre-Tertiary granite�flowed through a 1.5-in. choke with flowing tubing pressure of 2,000 psi. Suban is on the Corridor Block production-sharing area in South Sumatra.

Gulf Indonesia said the gas contained 5.5% carbon dioxide and will require very little processing to meet the sales gas requirement of 5%.

Bob Klassen, vice-president of operations for Gulf Indonesia, said the quality of the gas and the productivity of the Suban reservoir, demonstrated by both Suban 4 and the nearby Durian Mabok-2 well, meant development costs could be $1/boe or lower.

Suban-4 is undergoing an extended flow test. Suban-5, will be spudded 6 km from Suban-4 in the next few days.

"Approximately 1.1 tcf of gas from the Suban field will be dedicated to the Caltex II gas sales contract that is expected to be executed before yearend," said Bill Fanagan, president and CEO of Gulf Indonesia.

The company holds a 54% working interest in the Corridor Block PSC and is contract operator for Pertamina. Partners are Talisman (Corridor) Ltd., with 36%, and Pertamina, with 10%.
