Serica announces N. Sumatra gas production test results

UK-based oil, gas firm Serica Energy plc announced on Wednesday its production well test result from the Kambuna development field, Glagah-Kambuna TAC, offshore North Sumatra.

The Kambuna-2 production well tested the target Belumai reservoir over the 97 ft interval 7,245 to 7,342 ft below mean sea level and produced gas at a maximum stabilised rate of 33 million standard cubic feet per day (mmscfd) on a 72/64? choke. The flowing wellhead pressure during this test was 1,870 pounds per square inch (psi) and the maximum production rate was limited by the testing equipment, the company said.

A second test was carried out at production rate more representative of that required from the well when full field production commences. During this test, at a choke setting of 48/64?, the Kambuna-2 well produced gas at a stabilised rate of 19 mmscfd together with 2,000 barrels per day 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, it said

?This is an excellent production test result. Being able to produce Kambuna-2 alone at over 30 mmscfd goes a long way to meeting our target field production rate of around 55 mmscfd. The test also confirms that the initial condensate yield from the field is likely to be around 100 barrels per million cubic feet of gas, or about 5,000 barrels per day,? Serica CEO Paul Ellis said.

The Kambuna development wells are expected to produce at a total rate of 50 mmscfd, delivered at Pangkalan Brandan, about eight kilometres onshore and the site of a Pertamina gas plant and refinery

Serica is the operator of the Kambuna Field and holds an interest of 65% in the project. (denny)
