LONDON -- All three production wells in the Kambuna field, offshore North Sumatra, Indonesia, have now been tested and production has stabilized, according to field operator Serica Energy plc.
The final well, the Kambuna-4 production well, tested the Belumai reservoir over the 56 ft (17 m) interval 7,154 to 7,210 ft (2,181 to 2,198 m) true vertical depth (TVD) below mean sea level and produced gas at a stabilized rate of approximately 41 MMcf/d (1 MMcm/d) together with approximately 2,900 b/d of 54º API condensate. The flowing wellhead pressure during this test was 1,444 psi. The Kambuna-4 well was drilled as a deviated well from the surface location of Kambuna-2 and reached a maximum deviation angle of 55º from the vertical.
"We have now finished the completion and testing of all three Kambuna production wells and have achieved a combined stabilized gas rate of 114 MMcf/d (3.2 MMcm/d), which is considerably higher than we had expected, exceeding our initial sales gas target of 50 MMcf/d (1.4 MMcm/d) by a significant margin," says Serica CEO Paul Ellis said. "We shall be updating our Kambuna field reservoir model to investigate whether increased sales volumes can be justified, particularly given the strong gas prices now being realized for domestic gas sales."
