Sydney-listed Strike Energy on April 8 said results from its West Erregulla 4 (WE4) well in EP469 in Western Australia’s Perth basin are "above expectations".  

WE4 well has reached a final depth of 5,069m with wireline logging ongoing. Overall results are above expectations with initial wireline logs and petrophysics across the primary targets indicating the thickest Kingia penetration seen in the Basin to date at 155m. The results also show porosities of up to 19% in the Kingia and reservoir pressures at 4,898m of 6,821 psia. No gas water contact was encountered which deepens and extends the areal extent of the field, Strike said.

Strike spudded the well in January. It is the second of three appraisal wells in a planned campaign at West Erregulla, discovered in 2019. Strike operates the field with a 50% interest, while partner Warrego Energy also has 50%.

Going forward, Strike will look to finish the wireline logs to procure fluid samples and additional pressures across other formations. Once complete, the company will then condition the hole in preparation for running the final production casing string which will be cemented in place and then completed for the upcoming flow test across the Kingia sandstones.  

The well will then be kept on inventory for the first phase of development as a future producer. Post WE4 the rig will move to start drilling operations at West Erregulla 5.
