Strike Energy discovers gas in ‘staggering’ find

The Strike Energy and Warrego Energy joint venture has discovered gas in the Kingia sandstone as part of the West Erregulia-2 drilling campaign.

The Kingia formation was encountered at 4753 metres with gas on rock showing a gross gas column of at least 97 metres.

According to Strike, the lower section from 4790 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 per cent with peaks of up to 19 per cent.

Strike managing director Stuart Nicholls said the discovery exceeded the company’s expectations with higher reservoir quality than the Waitsia gas field.

“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,” Nicholls said.

Adelaide-based Strike believes it has unveiled a new conventional gas fairway, with initial results validating its geological model.

Early this month, the Strike-Warrego JV made another gas discovery in the Wagina sandstone in the Perth Basin.

“With gas discoveries in the Wagina and now the Kingia sandstones the West Erregulla campaign is company-changing for Strike,” Nicholls said.

“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.”
