Mosman Oil and Gas Limited (AIM: MSMN) the oil exploration, development, and production company, announces that a third-party technical report confirms that its 100% owned and operated permit EP 145 in Northern Territory, Australia has the essential ingredients for Helium and Hydrogen prospectivity, in addition to hydrocarbons.
A preliminary technical evaluation by Geognostics Australia Pty Ltd (“Geognostics”), has identified favourable scenarios for all three essential play elements related to viable helium and hydrogen plays in EP 145 (“Technical Report”). These components are also present in the Mount Kitty-1 and Magee-1 wells in the Amadeus Basin which flowed helium, hydrogen and hydrocarbons.
Geognostics Prospectivity Report
The key findings of the Technical Report are summarised below:
· Identified favourable scenarios for all three essential play elements related to viable helium and hydrogen plays including:
1) basement composition as a source of helium;
2) basement structure and connectivity via faults systems to support entrapment and / or migration of deeply-sourced gases (hydrogen and helium); and
3) possible seal facies above basement
· EP 145 is underlain by felsic-intermediate granites, a known source of helium in the basin.
· EP 145 contains the West Walker anticline with traps at multiple levels and migration pathways.
· The Gillen Formation evaporites interlayered with thin salt could be present and could act as viable seals.
Geognostics are independent experts with over 25 years’ experience of working for governments and companies in Australia and internationally( https://www.geognostics.com ). Its Technical Report comprehensively integrates geophysical, well and field mapping data from the permit with regional gravity, magnetics, seismic and well data to produce a review on the prospectivity in EP 145.
Five high-graded areas of prospectivity, including hydrocarbons, helium and hydrogen have been identified and ranked based on an enhanced understanding of the structural configuration and evolution of the Walker Creek Anticline. New play concepts have been developed for deeper, basement-derived helium and hydrogen exploration.
Based on the Geognostics report, and data from other wells in the Amadeus basin, Mosman has estimated gross Prospective Resource volumes for hydrocarbons, helium, and hydrogen associated with the Walker Creek Anticline as a lead within the boundaries of the EP 145 permit using a deterministic approach and applying the SPE PRMS standard.

The ongoing exploration work programme on EP 145 is to acquire seismic prior to drilling an exploration well. Mosman has applied for the required regulatory and Central Land Council (“CLC”) approvals. The CLC has conducted a site survey as a pre-requisite to land access approval for seismic acquisition.
