Strike Energy Limited has provided an update on West Erregulla on behalf of the EP469 Joint Venture.
Since the last update, Strike has performed the installation of the wellhead section for the 13-3/8” casing in preparation for drilling ahead with the second intermediate hole section.
The company advised that pressure testing of the wellhead seals was unsuccessful and upon investigation it was found that the slip and seal assembly for the 13-3/8” casing connection had failed.
With the slip and seal assembly not suitable for reuse, a new assembly will be required and is currently due to arrive in approximately one week.
Strike will now complete remedial and preparatory activities before the rig stands by the arrival and subsequent installation of the new slip and seal assembly.
Following this rectification work, the well drilling program will resume as planned.
About the West Erregulla Appraisal Campaign
Up to three appraisal wells will be drilled in the West Erregulla field, which is located in EP469.
The appraisal wells will be drilled down to approximately 5,000 metres with West Erregulla 3 designed to test the continuation of the commercial gas accumulation in the northern fault block and West Erregulla 4 (and 5) to appraise the reservoir distribution in the central fault block.
After various coring and logging operations all three wells will be flow tested (on success) and completed as future producers across the Kingia/High Cliff sequences for the proposed Phase 1 production operations.
The Wagina gas discovery made in West Erregulla-2 will be appraised during the West Erregulla 4 and 5 wells.
Strike Energy is the operator and the holder of a 50 per cent joint venture interest in EP469, and Warrego Energy holds the remaining 50 per cent joint venture interest.
