Sydney-based gas company AWE has produced more positive test results at its Waitsia gas field, with the highest flow rate to date recorded during recent flow testing.

AWE has a 50 per cent stake in the project, located in the Perth Basin, which has been touted as the largest onshore conventional gas discovery in Western Australia for decades.

The company said the testing achieved an instantaneous maximum flow rate of 90 million standard cubic feet per day at Watsia 4, believed to be one of the highest rates recorded onshore in Australia.

AWE chief executive David Biggs said the results had exceeded expectations.

“The results from Waitsia 4 are exceptional and the 2017 Waitsia appraisal program overall has been outstanding,” he said

“We have successfully confirmed a high-quality, conventional reservoir system with excellent well deliverability.

“Waitsia 4 completes the sub-surface works program. Results from Waitsia 4 will be incorporated into AWE’s ongoing evaluation of Waitsia reserves, and we expect to release a reserves update before the end of 2017.”

Mr Biggs said no further appraisal was required before a final investment decision for the Waitsia Stage 2 development.

The Waitsia 4 well will now be shut in for a brief pressure build-up survey prior to a series of flow tests at various choke settings, rates and well head pressures.

The testing program is expected to be completed by the end of November 2017.

Waitsia has the potential to supply at least 100 terajoules per day into the domestic market.
