Strike Energy announced that through the Strike-Warrego Joint Venture, it has made a significant gas discovery in the Wagina sandstone, part of West Erregulla-2 drilling campaign.
Strike said that the Wagina sandstone is estimated to be more than 74m in thickness and consists sections of clean sand with interpreted blocky porosity development, observed and interpreted from 4,106 to 4,180m.
The company said that the well section was completed without observing the end of the Wagina and there is potential for further Wagina sands to be encountered in the next section.
In addition, the wireline logs were loaded into its geological model and formation tops have been correlated to nearby offset wells.
The unexpected inflow of over-pressured gas into the well during the drilling of Wagina surpassed the expectations, according to the company.
Strike 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. With the primary target remaining to be drilled and potentially even more Wagina to come, this is a very exciting time for the company.”
Strike intends to acquire the remaining data taking into the gas discovery outcome in this early section of the well.
The company said thaat booking of a contingent resource will be subject to conducting a flow test on the Wagina sandstone in the future.
Located in EP 469, which is adjacent to and targeting analogous Permian gas sands of a similar size and nature as the Waitsia gas discovery, West Erregulla-2 will be drilled to a planned total depth of 5,200m.
