Waitsia-2 delivers excellent gas flows
Friday, Nov 10, 2017
  • Another excellent flow test result from the Waitsia field, onshore Perth Basin
  • Waitsia-2 achieves a maximum flow rate of 38.7 million standard cubic feet per day from the Kingia Sandstone
  • The Kingia Sandstone performance at Waitsia-2 sits between Waitsia-1 (25.7 MMscf/d) and Waitsia-3 (50 MMscf/d), reflecting difference in pay thickness and completion strings

AWE Limited (ASX: AWE), the Operator of Production Licences L1/L2 in the onshore Perth Basin, Western Australia, has commenced flow testing Waitsia-2, the second appraisal well in its 2017 three well test program on the conventional Waitsia gas discovery.

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 42 metre interval (3,173 metres to 3,215 metres Measured Depth Below Rotary Table) has been perforated.

Well clean-up operations commenced at approximately 07:45 hours AWST (Australian Western Standard Time) on Tuesday, 7th November 2017. On Wednesday, 8th November, at the end of a 19.8 hour clean up period, the well flowed gas at an instantaneous maximum rate of 38.7 million standard cubic feet per day (MMscf/d) and an average of 38.5 MMscf/d on an 80/64 inch choke at ~1,315 psig flowing well head pressure over a 2.1 hour period.

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

“Waitsia-2 has delivered another excellent flow test result from the Waitsia gas field. Net pay at Waitsia-2 is 30% of that in Waitsia-3, so to achieve a maximum flow rate of 38.7 MMscf/d is a fantastic result,” he said.

“The flow test confirms that the Kingia Sandstone at Waitsia-2 shares all the outstanding conventional reservoir properties observed at other wells in the field, particularly high porosity and low total inerts. Overall, these results underline the laterally extensive nature of this excellent reservoir system,” Biggs concluded.

The Waitsia-2 appraisal well has been 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. Once the Waitsia-2 flow test is completed, AWE will undertake the final flow test in the 2017 program at Waitsia-4. The testing program is expected to be completed by the end of November 2017.

Waitsia-3 is located approximately 16.5 kilometres east-south-east of Dongara, Western Australia, and 5.6 kilometres south-south-west of Waitsia-1.
