Warrego Energy Limited confirms flow test results from the West Erregulla-2 (WE-2) well located in EP469, onshore Perth Basin, Western Australia.
The testing program is designed to determine well deliverability from the Kingia Sandstone reservoir at the West Erregulla field, and to collect additional well data and gas samples for compositional analysis to feed into reserve certification calculations and gas marketing conversations. Three intervals totaling 48 metres, from 4,799 metres to 4,851 metres Measured Depth Below Rotary Table, were perforated and flowed.
Well clean-up operations commenced on 21 October 2019. On 24 October, following completion of the clean-up flow, the well flowed at a maximum rate of 69 million standard cubic feet of gas per day (MMscf/d) on a 2-inch choke at ~ 700 psig well head pressure over a 1-hour period.
Warrego Energy Group CEO & Managing Director, Dennis Donald, said:
“The flow test results from West Erregulla-2 have exceeded our initial expectations and demonstrate the exceptional quality of the Kingia reservoir in terms of porosity, permeability and pressure.
“This test further validates our view that West Erregulla is one of the best resources in the onshore Perth Basin,” he said
“We will incorporate data from the flow test into our models and anticipate being in a position to update our Contingent Resources for West Erregulla as soon as practical. We also look forward to advancing a gas balancing agreement with our joint venture partner and addressing ourselves to gas marketing options and opportunities to enable the development of the field.
“Beyond that, we are keenly progressing plans through the joint venture process with our 50% partner in the block to undertake further 3D seismic and drill additional delineation wells in 2020 to fully define the field and the extent of the resource. Only 1/3 of the EP469 Block area has been mapped by 3D seismic and we are optimistic that further West Erregulla-like resources will be identified during the 2020 campaign,” he concluded.
