Serica Energy Finds Gas with Kambuna-2 Appraisal Well

Serica Energy reports that its Kambuna-2 appraisal well, offshore North Sumatra, Indonesia, has successfully tested gas and condensate.

The Company is now preparing a Plan of Development for the Kambuna Field, which is located approximately 45 kilometers north of Medan, Indonesia's third largest city.

The well was drilled to a total depth of 7,963 ft below mean sea level ( and entered the target reservoir, the Belumai sandstone, at a depth of 7,278 The well encountered 64 ft of net gas pay sand with no indication of a gas-water contact.

The Belumai sandstone was tested over the 64 ft interval 7,278 to 7,342 on a 48/64' choke at a stabilized rate of 17.5 million standard cubic feet of gas per day (MMscfd) together with over 1,500 barrels per day of 55 degrees API condensate. The flowing wellhead pressure during this test was 2,000 pounds per square inch and the quoted production rate was limited by the testing equipment.

Serica will now examine the test results with the aim of submitting a Plan of Development for the Kambuna field to Pertamina (the Indonesian state oil company) before the end of 2005.

Serica CEO Paul Ellis said: "Serica's success in the first well that we have drilled as operator is a demonstration of the credible exploration experience of the management team and the dedicated efforts of our staff.'

'Our team has extensive knowledge in building businesses and we are now working on the development plans for the Kambuna field in order to bring the reserves to market at the earliest opportunity.'

Serica is operator and holds a 55% interest in Kambuna-2 through the Glagah Kambuna Technical Assistance Contract (TAC). Serica operates the Glagah Kambuna TAC on behalf of itself and its partners, Duinord Asahan Petroleum Inc, Jagen Asahan Pty Ltd, PT Gunakarsa Kambuna Energi and Greevest Asahan Pty Ltd.

The field discovery well, Kambuna-1, flowed gas at 13.9 MMscfd, along with 950 barrels/day of condensate, from an open-hole test over a 100-ft interval in the Belumai sandstone.

The Galaxy Driller will shortly leave Kambuna-2 to commence drilling the Togar-1 exploration well in the Asahan Offshore Production Sharing Contract (PSC), where Serica is the operator and also holds a 55% interest.

Serica will next week commence the acquisition of up to 1,500 line kilometers of 2D seismic in the Asahan Offshore PSC. This program is expected to take 15 days to complete and is being carried out to enable further drilling locations in the PSC to be confirmed.
