Another drilling success has been achieved in the gas-rich onshore Perth basin in Western Australia, this time with a successful appraisal well on the Walyering gas field.

Results of the Walyering-5 well exceeded pre-drill expectations, with four gas-charged reservoirs intersected with a total gross thickness of 116 metres and total net pay of 51 metres.

It is a high-quality, low CO2, conventional gas accumulation, said the operator Strike Energy.

Once drilling is complete, Strike said it plans to prepare the well for a production test in the first quarter next year that will feed into an independent joint venture resource statement.

This is Strike's second major success in the Perth basin this year, following on from the Greater Erregulla drilling successes.

Netherland, Sewell & Associates has certified 300 petajoules (283 billion cubic feet) of proven plus probable gross gas reserves at the West Erregulla field in one sandstone alone - the Kingia - giving Strike the confidence to proceed with a phase one development.

Strike's chief executive Stuart Nicholls said: “The results of the Walyering-5 well have exceeded Strike’s pre-drill expectations with thicker and better-quality gas charged sands being encountered across several reservoirs.

"These results are another example of the excellent geoscience outcomes that the Strike team continue to deliver, and this result bodes well for ongoing success throughout the basin.

“The co-location of the Walyering gas field with transmission infrastructure, better than pipeline quality gas and position on free-hold land, combines to make the potential for a very fast to market domestic gas development.

“Strike will now work with its partner Talon Energy to put together a plan for a fast and low-cost development before production testing the W5 well and having the resource independently certified.”
