West Erregulla JV raises Perth Basin potential

Strike Energy has revealed that initial drilling results at the West Erregulla 3 well in the onshore Perth Basin in Western Australia indicate conventional potential.

The company, on behalf of its EP469 joint venture with Warrego Energy, reported on Monday that drilling continues through the Dongara, Upper Wagina and Basal Wagina sandstones at West Erregulla 3 and has entered into the Caringynia shale.

Strike has collected logging while drilling (LWD) results across these Permian sequences and was drilling ahead at 4279m.

“Initial LWD results indicate conventional potential in the Dongara and Upper Wagina sandstones with six metres of net pay at an average porosity of 10.6 per cent,” the company reported.

Further wireline logging and testing will be required to indicate the materiality of these initial results, Strike added.

“These early observations correlate to strong gas shows seen in the well and are similar to other conventional Dongara and Wagina discoveries which have been made throughout the basin,” Strike stated.

The company is drilling ahead to the primary Permian targets in the Kingia and High Cliff Head Sandstones.

Upon reaching the upper Kingia, Strike will pull out of the hole to add further measuring and logging tools to the bottom hole assembly before drilling through the primary targets.

Up to three appraisal wells will be drilled in the West Erregulla field in EP469 by the 50:50 JV.

The wells will be drilled down to at least 5000 metres with West Erregulla 3 designed to test the continuation of the commercial gas accumulation in the northern fault block.
