Strike Energy has kicked off a 3D seismic campaign at its Walyering conventional gas discovery in the Perth Basin, where it has previously defined prospective resources of up to 263 billion cubic feet of gas and 6.3 million barrels of associated liquids condensate. The discovery was originally made in 1971 at about 3,350m depth, where the Walyering-1 gas well flowed at 13.5 million standard cubic feet per day.
