Walyering-5 confirms gas presence

Walyering-5 gas presence

Strike Energy and Talon Energy have confirmed the Walyering-5 appraisal well has the presence of a high-quality, low CO2, conventional gas accumulation in the Perth Basin.

The results exceeded expectations with both higher quality reservoir and the presence of additional net gas pay in deeper sands being observed.

Pressure data collected from the reservoir was measured at approximately 4,386psia with permeabilities of 274 mD.

Strike’s managing director and chief executive officer Stuart Nicholls said the thicker and better-quality gas charged sands that were encountered across several reservoirs exceeded expectations.

“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,” Nicholls said.

“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.”

Nicholls said Strike will now work with its partner Talon Energy.

“[Talon Energy will] put together a plan for a fast and low-cost development before production testing the W5 well and having the resource independently certified,” he said.

Talon’s CEO and executive director David Casey said the results were fantastic for the company and its shareholders.

“It’s not often that companies have success in their first drilling campaign in a new basin, and it is a credit to Strike and their team that they have been able to deliver this result for the Joint Venture,” Casey said.

“While we still need to undertake production testing, the results are yet another significant milestone as Talon looks to transition from explorer to producer in the near future.”

Casey said Talon now had other plans.

“On the back of this result our exploration efforts will now shift to other larger leads identified in EP447, as well as the analogous Condor prospect, which has a Prospective gas and condensate P50 Resource of 408BCF and 20.2MMbbls respectively,” he said.

Strike is running in and plans to cement 5-1/2-inch casing in place before completing the well across the Cattamarra Coal Measures with a 2-7/8-inch tubing string.

This comes after the announcement that Walyering-5 reached its final depth of 3435 m MD after only 13 days, eight days ahead of schedule.
