Australia’s Strike Energy said its joint venture with Warrego made a gas discovery in the Wagina sandstone as part of the West Erregulla-2 drilling campaign.
The Wagina sandstone was found to be ~74 meters plus in thickness and made up of sections of clean sand with interpreted blocky porosity development that was observed on drilling to have hydrocarbons present throughout. This section was observed and interpreted from 4,106 to 4,180m.
The well section was finished without observing the end of the Wagina and there is potential for further Wagina sands to be encountered in the next section.
Strike’s managing director, Stuart Nicholls said, “This is a significant discovery and comes from a secondary target which carried a low pre-drill probability of success. Importantly, it provides further confidence in Strike’s predictions of good porosity development within Permian reservoirs being possible at depths greater than that of Waitsia and to the South-East.”
“With good porosity trends continuing with depth, Strike believes that it is on track to find a good quality reservoir within its primary target in the Kingia-High Cliff,” he said.
“With the primary target remaining to be drilled and potentially even more Wagina to come, this is a very exciting time for the company,” concluded Nicholls.
West Erregulla-2 is being drilled in EP 469, which is adjacent to and targeting analogous Permian gas sands of a similar size and nature as the Waitsia gas discovery. The well will be drilled to a planned total depth of 5,200m.
The remaining targets include a conventional gas target in the Basal Wagina sandstone and the primary gas sand sequence in the Kingia High Cliff.
Strike Energy is the operator and the holder of a 50 percent joint venture interest in EP469, and Warrego Energy the holder of the other 50 percent joint venture interest.
