The 50-50 joint venture of Strike Energy Ltd. and Warrego Energy Ltd. in onshore North Perth basin permit EP469 began the first of three new appraisal wells on West Erregulla gas field.
West Erregulla-3 spudded Sept. 21. It will be followed immediately by Nos. 4 and 5.
Strike, as operator, said all three wells will be drilled to depths of about 5,000 m.
West Erregulla-3 is designed to determine the continuation of the commercial gas accumulation in the northern fault block, while West Erregulla-4 and -5 will appraise the reservoir distribution in the central fault block.
The wells will be cored and logged before being flow tested and, if successful, completed as future producers across the Kingia/High Cliff reservoirs for the proposed Phase 1 field development.
The discovery of gas in the Wagina reservoir in West Erregulla-2 also will be appraised during the West Erregulla-4 and -5 drilling program.
The JV made the three-reservoir West Erregulla discovery during the drilling of West Erregulla-2 in August-September 2019.
Strike and Warrego still aim to bring West Erregulla Phase 1 development on stream during first-half 2022 via a 50 terajoules/day processing plant and connecting pipeline to the nearby Dampier-Bunbury trunkline.
