Kambuna Field Tests at 33 Mmscf/d for Serica

Serica Energy plc provides an update on development activities in the Kambuna field, offshore North Sumatra, Indonesia.

Having completed the drilling phase of the Kambuna field development programme with GSF Rig 136, production tests are being carried out on the three production wells and the results of the first test are now available.

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-in. 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.

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-in., 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 course of the next few weeks.

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

Serica CEO Paul Ellis 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."

Paul Ellis MA (Oxon) Engineering and Serica's Chief Executive, who has over 35 years' experience in the upstream oil and gas industry, has reviewed and approved the technical information contained in this announcement.
