HOUSTON, May 11 -- Serica Energy Corp., Toronto, has signed a contract with Indonesian agent PT Lins Petrotama Energi for the use of Northern Offshore Ltd.'s Galaxy Driller semisubmersible for a two-well drilling program off North Sumatra. The $5.7 million contract includes drilling and ancillary services.
The Galaxy Driller will spud the first well, Kambuna-2, on the Glagah Kambuna technical assistance contract (TAC) to appraise Kambuna natural gas-condensate field, discovered by Bow Valley Energy Ltd. in 1986. Kambuna-2 will be drilled to 8,200 ft. TD.
The field's Kambuna-1 discovery well flowed gas at 13.9 MMscfd and condensate at 950 b/d from an open-hole test over a100-ft interval in the Belumai sandstone, Serica said. The TAC, in which Serica holds a 69.4% interest, is off North Sumatra, 45 km north of Medan.
Serica recently concluded an agreement with PT Gunakarsa Glagah Kambuna Energi and Indonesia's national oil company Pertamina to extend the rehabilitation period of the TAC to Dec. 16. The TAC expiration date remains unchanged at Dec. 16, 2016.
In the second project, Galaxy Driller will drill exploration well Togar-1 on the Serica-operated Asahan offshore production-sharing contract. The PSC surrounds the Glagah Kambuna TAC on three sides.
Togar-1, to be drilled to 6,300 ft TD, will investigate a series of possible hydrocarbon-bearing sands in the Baong sandstone formation.
Galaxy Driller, a second-generation Mariner-design semi built in South Korea in 1977, currently is in Singapore undergoing an extensive refit and upgrade. The first well is expected to be spudded in June.
