LONDON -- Having completed the drilling phase of the Kambuna field development program, production tests are being carried out on the three production wells.
The first test on the Kambuna-2 well offshore North Sumatra, Indonesia tested at a stabilized rate of 33 MMcf/d, according to operator Serica Energy.
Kambuna-2 tested the target Belumai reservoir over the 97-ft (30-m) interval 7,245 to 7,342 ft (2,208-2,238 ft) below mean sea level and produced gas at a maximum stabilized rate of 33 MMcf/d on a 72/64-in. choke. The flowing wellhead pressure during this test was 1,870 psi and the maximum production rate was limited by the testing equipment.
A second test was carried out at production rate more representative of that required from the well when full field production commences, Serica says. During this test, at a choke setting of 48/64 in., the Kambuna-2 well produced gas at a stabilized rate of 19 MMcf/d together with 2,000 b/d of 53 degrees API condensate, at a flowing wellhead pressure of 2,280 psi.
Further production tests will be carried out on the Kambuna-3 and Kambuna-4 wells over the next few weeks.
Serica holds an interest of 65% in the Kambuna field project.
