Well improvements increase production at offshore Thailand fields

Offshore staff

SINGAPOREKrisEnergy has issued an update on its development programs in the Asia/Pacific region.

The B8/32 and B9A complex in the Gulf of Thailand continues to produce at the highest rates for more than three years due to wireline zonal recompletions.

During 2Q seven infill wells were drilled with production averaging 52,289 boe/d.

In June the first export cargo from the Nong Yao oil field in G11/48, also in the Gulf, was lifted to China. However, the contract area acreage of the concession was reduced by more than two-thirds following the Department of Mineral Fuel’s (DMF) approval of the Reservation Area application.

The license now covers four discreet areas in the Gulf of Thailand. Drilling of four infill wells started last month, and these are expected to lift production, currently 9,722 b/d, by a further 4,000 b/d.

DMF approved the Reservation Area application for G10/48 in May, reducing the acreage size to 1,783 sq km (688 sq mi).

Production at the Wassana field in this concession has averaged 9,102 b/d, slightly below expectations, most likely due to mechanical problems at up to five wells rather than a reservoir issue. Plans are under way to remedy the problem.

DMF has also approved the Reservation Area application for G6/48, which has been halved to 284 sq km (109 sq mi) to comprise two separate areas in the Gulf of Thailand. One is the Rossukon Production Area, containing the Rossukon oil development, which was approved last November.

Indonesia’s Environment Ministry has approved the environmental impact assessment for the Lengo gas development in the Bulu PSC offshore East Java, Indonesia. Approval of the environmental permit is pending.

Six companies have qualified for the engineering, procurement, construction, and installation tender.

Final versions of transaction documents for the offshore Cambodia block A oil development are ready for signature and will be followed by enactment of supporting legislation. KrisEnergy has completed a review of the subsurface, facilities, schedule, cost, crude marketing, and economics.
