Roc Oil Highlights Workover Program at BMG Oil and Gas Field
Anzon Australia Pty Ltd, a wholly owned subsidiary of ROC, has provided an update on BMG Oil and Gas Field operations.
Drilling and Workover Program
Production testing from the Basker-3 ("B3") well commenced on August 1, following the successful installation of a multi-zone SMART completion, designed to optimize selective production from targeted Basker intra-Latrobe reservoirs. B3 is expected to produce at a rate of approximately 2,000 BOPD (ROC: 600 BOPD) on completion of the current reservoir clean up and testing program.
The Basker-7 ("B7") development well is drilling ahead at a depth of 3,537 meters. The well target depth (3,950 meters) is expected to be reached during the coming week, ahead of schedule. B7 is expected to produce at a rate of approximately 3,000 BOPD (ROC: 900 BOPD) on successful completion of tie-in and commissioning activities in September.
The Basker-2 ("B2") well has been shut-in and isolated following identification of a minor leak on the subsea choke located on the Basker A manifold ("BAM") during normal production operations. The leak was isolated and relevant authorities were informed. A series of isolation and pressure tests have confirmed the BAM's operational integrity and production from other wells operating through the manifold is continuing.
Planning for repair of the B2 choke is underway. As previously advised, BMG will be offline for approximately eight weeks from mid-September for planned inspection and maintenance programmes and installation of a gas compressor package on the Crystal Ocean FPSO. This planned downtime will provide an operational window for B2 choke repairs. An Installation Support Vessel, which is scheduled to be on site to undertake B7 tie-in and commissioning activities in early September, is also being considered for use to accelerate B2 choke repairs.
BMG is now producing at an average rate of approximately 1,100 BOPD pending the successful completion of the B3 and B7 wells. Additional production from B3 and B7 wells is expected to increase the average rate to approximately 6,000 BOPD before the planned downtime in mid-September. On successful completion of B2 repairs, the average production rate is expected to increase to approximately 10,000 BOPD.
Participating interests in the BMG Joint Venture, subject to closing of the sale by ROC of a 10% participating interest to Pertamina, are as follows:
- Anzon Australia Pty Limited (Operator); 30%
- Beach Petroleum Limited; 30%
- CIECO Exploration and Production (Australia) Pty Ltd; 20%
- Sojitz Energy Australia Pty Ltd; 10%
- PT Pertamina Hulu Energi; 10%
ROC 2009 Production
ROC will provide an updated 2009 production forecast once the timing for repair of B2 is finalized and the current BMG drilling and workover program is completed. However, ROC is now unlikely to achieve the 2009 production target of 11,000 BOEPD.
