Strike Energy has announced two significant gas discoveries made in the Erregulla Deep-1 exploration well in the Perth Basin.
The two discoveries include 26m of net gas pay within the Kingia Sandstone with an average porosity of 13 per cent and 2m of net gas pay within the High Cliff Sandstone with an average porosity of 11 per cent.
The well was drilled to a total depth of 5225m, making it the deepest well drilled onshore Australia.
Multiple gas samples have been acquired in both discoveries and have confirmed good permeabilities, gas gradients and materially lower CO2 contents than observed at West Erregulla.
“The discoveries at Erregulla Deep are higher quality than Strike anticipated prior to drilling, with reservoir quality, formation pressures and lower CO2 content all exceeding expectations relative to the West Erregulla wells,” Strike Energy managing director Stuart Nicholls said.
“The Erregulla Deep-1 well is the most easterly and deepest penetration of the Kingia-High Cliff Sandstones in the basin to date and is a significant play extender to the East and at depth for Strike’s 100 per cent acreage.
“Erregulla Deep will be completed as a future producer and on a successful flow test may add to the overall developable resource in EP469/L25, which includes the West Erregulla gas field’s independently estimated gross 452PJ of 2P Reserves plus 2C contingent resources.”
