Energy Resources, Norwest find gas in Perth basin
Australian explorers Energy Resources and Norwest Energy on September 8 reported a "significant" conventional gas discovery at Lockyer Deep-1 in the Perth basin.
Norwest said that elevated gas readings were observed within the High Cliff Sandstone from 4,172 m and 4,214 m and additional hydrocarbon potential has also been encountered within the shallower Dongara/Wagina formations.

“Apparent absence of gas water contact in Kingia supports the case for a large resource across the greater Lockyer Deep/North Erregulla Deep structure,” Norwest said.
Oil fluorescence was observed over a 158 m section from the top Dongara Sandstone and into the Wagina formation. Fair to good oil shows were observed within the upper 68 m of this interval, of which approximately 48 m is interpreted as the Dongara Sandstone, Norwest added.
A comprehensive wireline logging programme is now being run across the entire bottom hole section in order to fully appraise the gas/oil deliverability of the Dongara/Wagina/Kingia/High Cliff intervals, the company said.
“Positive results from the programme will lead to Lockyer Deep-1 being completed for production testing, for which planning has already commenced,” it said.
Lockyer Deep-1 is located within exploration permit EP368, a joint venture between Norwest (20%) and Energy Resources (80% and operator). Energy Resources is a wholly-owned subsidiary of Sydney-listed Mineral Resources.
