LONDON -- The Kambuna #3 and #4 deviated development wells in the Kambuna field, offshore North Sumatra, Indonesia, are being batch drilled from the Kambuna production platform, according to operator Serica Energy. The platform was installed earlier this year at the Kambuna #2 well, the first of the three planned development wells.
Kambuna #3 has been drilled to 7,483 ft (2,267 m) TVDSS. The well entered the target Belumai reservoir at 7,166 ft (2,184 ft) TVDSS and encountered gas-bearing sands over an interval of 107 ft (33 m) with a net pay of 77 ft (23 m). There was no indication of a gas/water contact.
A 7-in (18-cm) production liner has been set in Kambuna #3 and the well will be suspended while the remaining section of Kambuna #4 is drilled. Later in April all three development wells will be completed for production and short production tests will be carried out.
The company anticipates that production from the field will commence in December 2008. Serica holds an interest of 65% in the Kambuna field project.
