Strike gathers confidence at West Erregulla after testing

Strike Energy has returned “outstanding” flow test results from the Kingia sandstone at the West Erregulla gas project in Western Australia.

The company announced that the clean-up flow of the West Errugulla 2 gas exploration well had been completed, the multi-rate flow test and pressure build-up program commencing.

A testing program is designed to determine well deliverability with a series of flow tests at different choke settings, rates and wellhead pressures and collection of gas samples for compositional analysis.

Kingia Sandstone is the zone being tested, with 48 metres of perforations placed across the interval between 4799 metres and 4951 metres measured depth.

A flow rate of approximately 69 million standard cubic feet per day of gas was achieved through a two-inch choke with 700 psig wellhead pressure over a one-hour period.

Production was limited by surface equipment constraints indicating the reservoir has the capacity to flow at higher rates.

The multi-rate testing has exceeded initial expectations and provided further reservoir information consistent with other high rate North Basin Basin gas well.

Strike chief executive Stuart Nicholls said the flow rate from the Kingia formation confirmed interpretations of a very high quality reservoir with excellent productivity.

“This result, along with the significant upside in the High Cliff and Wagina formations, increases the attractiveness of West Erregulla as the company progresses towards appraisal and development of these resources in the Perth Basin,” Nicholls said.
