Strike JV Finds 'Significant' Gas in Perth Basin

Australian Strike Energy August 27 said Strike-Warrego joint venture has made a ‘significant’ gas discovery in the Kingia sandstone as part of the West Erregulla-2 drilling campaign.

The Kingia formation was encountered at 4,753 metres with gas on rock showing a gross gas column of at least 97 meters, Strike said. The lower section from 4,790 metres onwards is made up of several high-quality large units of clean sand with thick blocky porosity development. This 67 metre section, which has high gas saturation throughout, is interpreted to have net pay of 41 metres and an average porosity of 14.3% with peaks of up to 19%, Strike added.

“This is truly an exceptional outcome. The Kingia results at West Erregulla have exceeded Strike’s highest expectations and indicate a significant discovery that appears to have higher reservoir quality than the Waitsia gas field,” managing director Stuart Nicholls said. “With West Erregulla-2 now being one of the deepest wells ever drilled onshore Australia and finding such excellent quality sandstone reservoirs, the subsurface paradigms of the Perth Basin are shifting.”

The West Erregulla-2 campaign is taking place within EP469 in the North Perth Basin in Western Australia. Strike is the operator and the holder of a 50% joint venture interest, and Warrego Energy is the holder of the other 50%. 

Nicholls said that the company believes it has unveiled a new conventional gas fairway, with these initial results validating its geological model.

“With gas discoveries in the Wagina and now the Kingia sandstones the West Erregulla campaign is company-changing for Strike. With the well drilling ahead to the High Cliff sandstones which show an even better anomaly than the Kingia at West Erregulla, the chance of adding a further material discovery looks promising,” Nicholls said.

Strike said it will continue drilling through to a nominal final depth of 5,200 metre at the top of the Holmwood Shale. This will be followed by wireline logging, side wall coring, casing and running of a production completion followed by a flow test.
