West Erregulla-5 confirms large, high-quality gas resource
Strike Energy Ltd has confirmed a large, high-quality gas resource in the main Kingia formation reservoir of West Erregulla gas field, with initial well results in line with expectations.
The West Erregulla-5 appraisal well in the onshore North Perth basin of Western Australia was drilled to 5,015 metres total depth in the Holmwood shale. Kingia was encountered at 4,771 metres, which was shallower than expected. The formation had a gross thickness of 183 metres and comprised almost one single unit of very clean sand displaying thick blocky porosity.
Gas was observed throughout the Kingia which is interpreted to have a net pay of 32 metres and an average porosity of 10% with highs of 15%. Reservoir pressures will be captured in forthcoming wireline runs.
The underlying High Cliff sandstone was observed to have negligible reservoir development, but additional pay was identified in shallower Permian reservoirs that will be subject to further testing.
West Erregulla-5 lies about 1.7 km due north of the West Erregulla-2 discovery well and is the third appraisal in the field in permit EP469.
Strike will conduct additional wireline logging to gather fluid samples, pressures, and other data prior to running production casing and a flow test of the reservoir.
The appraisals were designed to test reservoir distribution in the field, and all will be completed as future producers across the Kingia Sandstone for the proposed Phase 1 production operations.
Strike is operator with 50% interest. Warrego Energy Ltd holds the remaining 50%.
