Malaysia: Balai cluster appraisal well gauges oil

BC Petroleum Sdn. Bhd., the company incorporated to operate and manage the four-field Balai Cluster Risk Service Contract offshore Sarawak, Malaysia, has completed initial tests of the first well, Bentara-2.

The Bentara-2 well in Bentara field achieved rates of 1,685-2,275 b/d of 30° gravity oil on a 40/64-in. choke from a perforated interval at 2,665-71 m measured depth below rotary table. The test accessed an estimated 9.4-m reservoir net pay section, said operator ROC Oil Co. Ltd.

Logs indicate as many as 14 reservoir sections in the well with a combined estimated hydrocarbon pay thickness of more than 100 m. Now shut-in, the well awaits arrival of the early production vessel to conduct extended production testing of the remaining reservoirs.

BCP will move the rig to Balai field, 25 km east of Bentara, to drill the Balai-2 well. The Balai Cluster RSC consists of Bentara, Balai, Spaoh, and West Acis fields.

Drilling of appraisal wells is part of the predevelopment phase that began in early 2012. Upon successful completion of the predevelopment phase and agreement on the fields’ economic viability, BCP will submit a field development plan and progress to develop the fields.

BCP shareholders are ROC Oil 48%, Dialog Group 32%, and Petronas Carigali 20%.
