Australian vitality firm Strike Power Ltd as operator of the EP469/L25 Joint Enterprise, which incorporates the West Erregulla fuel area, accomplished the movement testing program on the Erregulla Deep-1 (ED-1) discovery effectively in EP469 with glorious outcomes, the corporate stated.
The EP469 three way partnership is a 50-50 partnership between Strike Power and Warrego Power 469 Pty. Ltd. Strike Power stated in a media launch that ED-1 is the deepest effectively ever drilled onshore Australia. The corporate flow-tested the Kingia fuel discovery individually and the Excessive Cliff fuel discovery by way of a comingled take a look at.
ED-1 had 79 toes of perforations throughout the Kingia from 15764 toes true vertical depth beneath sea degree (TVDSS) and 39 toes of perforations throughout Excessive Cliff from 15912 toes TVDSS. Multi-rate movement checks and build-ups, together with downhole gauges and manufacturing logging, had been carried out. The ED-1 effectively demonstrated sturdy efficiency all through the testing interval, confirming exceptionally excessive reservoir stress and vital permeability within the Kingia Sandstone, the corporate stated in a press launch.

On a standalone take a look at the Kingia produced at a max instantaneous price of 60 million normal cubic toes per day (MMscfd) and a stabilized price of 53 MMscfd on a 46/64” choke at a flowing tubing head stress (FTHP) of 5,515 psi.
“ED-1 has carried out exceptionally while on take a look at over the past 3 weeks. The take a look at has confirmed that ED-1 is among the finest wells ever drilled within the Perth Basin with extraordinarily excessive deliverability and low impurity. The effectively end result has vital optimistic impacts on the West Erregulla area growth and the neighboring prospectivity the place Strike has a serious 100% owned tenement place”, Strike’s Managing Director & Chief Govt Officer, Stuart Nicholls, stated.
Resulting from ED-1’s potential as a future producer for the West Erregulla fuel area, testing charges had been maintained inside a conservative vary to make sure effectively integrity and security, the corporate stated. An absolute open movement (AOF) calculation suggests the effectively might produce at a most price of 400-450 MMscfd, highlighting the reservoir’s high quality. No sand or formation water was produced throughout testing, and the fuel composition was a low impurity dry fuel, with CO2 ranges round 4 p.c, decrease than these on the West Erregulla fuel area, Strike Power stated.
The corporate inhibited Excessive Cliff zone testing as a result of high quality of the Kingia fuel discovery. The Excessive Cliff discovery will likely be reserved for a second section of the effectively’s life, which can embody the zone of excessive prospectivity encountered within the Irwin River Coal Measures.
ED-1 will now be suspended as a future producer and the testing gear will likely be demobilized from the effectively website, Strike Power stated. The corporate will undertake engineering, documentation, costing, and planning to incorporate the ED-1 effectively throughout the submission of the sphere growth plan to the three way partnership.
