SYDNEY -- Production testing is under way from the Basker-3 (B3) well in the Bass Strait, according to operator Anzon Australia, a subsidiary of ROC.

This follows the successful installation of a multi-zone SMART completion, designed to optimize selective production from the targeted Basker intra-Latrobe reservoirs. B3 should produce at around 2,000 b/d once the current reservoir clean-up/test program is concluded.

The Basker-7 (B7) development well is currently at a depth of 3,537 m (1,078 m), and should reach target depth of 3,950 m (1,204 m) in the next few days. This well is expected to deliver around 3,000 b/d once tie-in and commissioning work is completed in September.

However, the Basker-2 (B2) well has had to be shut-in and isolated following a minor leak on the subsea choke on the Basker A manifold. Isolation and pressure tests have confirmed the manifold’s production integrity, and production is continuing from other wells.

Anzon is working on a repair plan. The Basker-Manta-Gummy (BMG) production system will be offline for around eight weeks from mid-September for inspection and maintenance and installation of a gas compressor package on the Crystal Ocean FPSO. An installation support vessel, due on site to conduct tie-in and commissioning of B7, may also be deployed to accelerate repair of the B2 choke.

BMG is currently procuring at an average of 1,100 b/d, but further additions from B3 and B7 should lift this rate to around 6,000 b/d before the planned downtime in mid-September. Once B2 is also restored, output will increase to around 10,000 b/d.
