Basker-5 well workover suspended

Offshore staff

SYDNEY, Australia -- The Basker-5 (B5) well workover has been suspended and the semisub Ocean Patriot has moved to the Basker-3 (B3) well workover, according to Anzon Australia.

The B5 workover program was designed to isolate water production through the installation of a cement plug to isolate the lower reservoir sands. The production log acquired during the workover showed a more complex combination of water and gas flowing within the well, the company reports. The workover has been suspended and the isolation procedure is under review.

As a result, the oil acceleration benefits from B5 (assessed at 800 b/d of oil prior to the start of the program) are currently uncertain, the company says.

Subject to further assessment of the log results, the company may carry out a revised B5 workover at the end of its current drilling campaign, which includes the B3 workover and the Basker-7 (B7) development well.
