LONDON -- Development of the Chim Sáo field off southern Vietnam remains on schedule, according to Premier Oil.
During the first half of 2010, installation was completed of the production platform jacket and the 100-km (62-mi) pipeline which will transport gas from Chim Sáo to the Nam Con Son trunkline.
Development drilling started in mid-June, with eight wells to be drilled ahead of first oil. The topsides for the wellhead platform have been installed offshore. At end-July, conversion of the Lewek Emas FPSO in Singapore was 60 % complete. The finished floater will be moved out to the field during the first half of 2011.
Also under way is detailed subsurface and facilities studies to define the development plan for the Dua field, which could be tied in to Chim Sáo at a later date. The partners aim to settle on a final development project decision in the first part of next year.
Elsewhere in the Vietnamese offshore sector, Premier says work has continued on the Cá Rong Do oil discovery in the Nam Con Son basin block 07/03 ahead of a planned appraisal well early in 2111. During July, 3D seismic data acquisition started over the central area of the block and over block 104-109/05 offshore northern Vietnam, ahead of exploration drilling planned during mid-2011.
In the Natuna Sea block A offshore Indonesia, Premier says the Gajah Baru project is progressing well. This is the first of various fields which will be developed to supply additional gas to Singapore and Batam under three new gas sales agreements signed in 2008.
Fabrication continues at two yards in Batam of the wellhead platform and the central processing platform. By end-July, the overall Engineering, Procurement, Construction, and Installation contract was over 63% complete. The wellhead platform currently is being installed, with development drilling due to start in September. Premier adds that the project remains on track to deliver first gas in October 2011.
With demand for gas in the area increasing, Premier has drawn up a five-year exploration plan for the block, with a prospect inventory review in progress to determine the remaining risked resource potential. Two exploration wells could be drilled next spring on the Anoa Deep and Biawak Besar prospects.
On the Premier-operated Tuna block, preparations are under way for exploration drilling later this year on the Gajah Laut Utara and Belut Laut structures. Processing and interpretation have been completed of an 850-sq km (328-sq mi) 3D seismic survey.
Seismic attribute analysis has highlighted several prospects with a seismic response consistent with what was observed in the hydrocarbon-bearing reservoirs of the Cá Rong Do well in Vietnamese block 07/03, immediately north of Tuna.
