A joint venture of Energy Resources Ltd. and Norwest Energy NL made a conventional gas discovery in the Lockyer Deep-1 wildcat onshore North Perth basin permit EP368 in Western Australia.
Gas has been encountered in the target Kingia and underlying High Cliff sandstone reservoirs.
Norwest Energy reports that logging-while-drilling resistivity separation indicates good inferred porosities throughout a gross interval of 26 m in the Kingia (4,041-4,067 m). Elevated gas readings continued to the top of Bit Basher shale at 4,109 m well depth.
Available data suggests that no gas-water contact is evident in the Kingia which supports the case for significant resource potential across the greater Lockyer Deep-North Erregulla Deep structure.
Elevated gas readings also have been observed in a gross interval of 42 m in the High Cliff reservoir (4,172-4,214 m).
Additional hydrocarbon potential, including oil shows, was encountered within a 158 m gross interval in the shallower Dongara-Wagina formations.
The joint venture is running a comprehensive wireline logging program across the entire bottom-hole section to appraise the gas-oil deliverability of all four hydrocarbon intervals. If positive results are obtained, the Lockyer Deep-1 well will be completed for production testing.
Lockyer Deep is a three-way dip structure, fault closed to the west.
The discovery lies in permit EP368, but the overall structure spills into the western sector of adjoining permit EP426. EP368 also contains the undrilled Greater Springy Creek prospect on trend to the north.
The Lockyer Deep discovery well lies 10 km north of Strike Energy-Warrego Energy’s 2018 West Erregulla gas discovery now being readied for development. It is also 15 km east of Mitsui-Beach Energy’s Waitsia producing gas field.
Energy Resources is operator of Lockyer Deep with 80% interest. Norwest Energy NL holds 20%.
Energy Resources is a division of Mineral Resources Ltd. which acquired the assets of Empire Oil & Gas in 2017 and folded them into the Energy Resources subsidiary that was formed in 2018.
