AWE: Highest Waitsia flow rate to date - 90 MMscf/d at Waitsia-4
Wednesday, Nov 22, 2017
AWE Limited (ASX: AWE), the Operator of Production Licences L1/L2 in the onshore Perth Basin, Western Australia, has commenced flow testing the Waitsia-4 well which will complete the appraisal program on the conventional Waitsia gas field for 2017.

The testing program is designed to determine well deliverability from the southern extent of the Waitsia field and to collect gas samples for compositional analysis. The zone being flow tested is the Kingia Sandstone, where a 50 metre interval (3,370 metres to 3,420 metres Measured Depth Below Rotary Table) has been perforated.

Well clean-up operations commenced at 15:48 hours AWST (Australian Western Standard Time) on Monday, 20 November 2017. On Tuesday, 21 November, at the end of a 17 hour clean up period, the well flowed gas at an instantaneous maximum rate of 90 million standard cubic feet per day (MMscf/d) and an average of 89.6 MMscf/d on a 96/64 inch choke at ~2,395 psig flowing well head pressure over a 23 minute period.

AWE’s CEO and Managing Director, David Biggs, said:

“The results from Waitsia-4 are exceptional and the 2017 Waitsia appraisal program overall has been outstanding. We have successfully confirmed a high quality, conventional reservoir system with excellent well deliverability.

“Overall, these results have exceeded our pre-test expectations and reinforce our plans for the Stage 2 development, particularly the low number of wells initially required and the straightforward facilities design.

“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. No further appraisal is required before a Final Investment Decision (FID) for the Waitsia Stage 2 development,” Biggs concluded.

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.

The Waitsia-4 appraisal well is located approximately 18.5 km south-east of Dongara, Western Australia, and 3.3 km north-northeast of Waitsia-3.
