The AWE Ltd.-operated joint venture with Origin Energy Ltd. has tested a significant flow of natural gas from its Waitsia-1 well in production licenses L1/L2 in the north Perth basin onshore Western Australia.
The well flowed at a rate of 24.7 MMcfd of gas from the High Cliff Sandstone, the rate only being constrained by tubing size.
AWE says the flow is twice that of the nearby Senecio-3 well and is only from the first zone of interest in the well. The Kingia Sandstone deep gas play is still to be tested.
The Waitsia tests are designed to determine well delivery rates from the two conventional gas reservoirs as well as to collect samples for analysis.
The High Cliff Sandstone is a 23.5-m thick interval in the well below 3,382 m.
Waitsia-1 will now be shut in to allow pressure build-up prior to a series of flow tests later this week through various choke settings, rates, and wellhead pressures.
A plug will then be set to isolate the lower interval prior to a similar test of the Kingia Sandstone. This reservoir tested at 12.3 MMcfd at Senecio-3.
AWE plans a rapid development of 9 months with a pipeline planned to connect Waistia-1 and Senecio-3 to the Xyris production facility near the Waitsia-2 well.
AWE and Origin each have 50% interest in the licenses.
