Bentara appraisal well flows oil offshore Malaysia

Offshore staff

SYDNEY, Australia – BC Petroleum (BCP) has completed initial testing of the Bentara-2 well offshore Sarawak, East Malaysia.

Bentara is one of four fields in the Balai Cluster risk sharing contract (RSC), which comprises Balai, Spaoh, and West Acis. BCP’s shareholders are ROC Oil, Dialog Group, and Petronas.

After finalizing the logging program, the well was completed and perforated over a 6-m (19.7-ft) interval with an estimated reservoir net pay section of 9.4 m (30.8 ft).

The zone was tested over 23 hours to prove up reservoir production potential. The test achieved a stable oil rate in the range 1,685-2,275 b/d on a 40/64-in. choke, and oil gravity of 30° API.

Bentara-2 well has been shut-in until the early production vessel arrives to perform extended production testing of the remaining reservoirs. Up to 14 reservoir sections have been identified in the well from logging data, with total estimated pay potential of more than 100 m (328 ft).

The drilling rig is about to relocate 25 km (15.5 mi) to the east to the Balai field to drill the Balai-2 well.

Drilling of the Balai Cluster RSC appraisal wells is part of the pre-development phase that started early this year. On completion, and assuming agreement on the fields’ viability, BCP will submit a field development plan.
