MELBOURNE, Mar. 29 -- Indonesia’s Pertamina let a contract to Cooper Energy Ltd., Perth, for operation and development of three small oil fields in south Sumatra.

The fields—Sukananti, Tangai, and Bunian—have been on stream previously and have produced to date a total of just over 1 million bbl.

Cooper paid a signature bonus of $861,888 and plans a 24 sq km 3D seismic survey plus a new development well and three workovers of existing wells plus infrastructure upgrades. The program is expected to cost $6.8 million over 3 years.

Bunian is still producing 60 b/d of oil through a single well; however the other two fields have been shut in pending workover operations.

Tangai was producing through four wells, while Sukananti was producing from one well.

Cooper Energy intends to redevelop the fields to produce a further 1 million bbl of oil. The company also anticipates further exploration and appraisal potential within the block, and this will be assessed as part of the work program.

Private Indonesia firm Mega Adhyaksa Pratama is a joint venture partner in the field with 10%.
