An independent reservoir rock characterisation study has revealed promising geological parameters for hydrogen generation and storage at Gold Hydrogen Ltd (ASX:GHY)'s flagship Ramsay Project in South Australia
All necessary ingredients for hydrogen
The geological parameters appear to have all the necessary ingredients for the generation and accumulation of hydrogen gas.
Historical well chip samples from legacy wells on the PEL 687 permit, which falls within the project boundary, were obtained from archive storage and tested in laboratory conditions by an independent scientific organisation.
Key indicators, including porosity (the storage capacity for hydrogen) and permeability (the ability for hydrogen to flow) were found across offset wells, supporting the belief that the Ramsay area has the capacity to flow hydrogen gas.
The presence of microfractures in Cambrian limestone and fractured basement further supports the company's theories on hydrogen migration potential.
This study analysed 34 samples and found hydrogen presence in 31, confirming hydrogen can be stored and transported in the rock matrix.
Independent mapping of the formation confirms the magnetic results from the company’s airborne survey, published on August 9.
Hypothesis supported
Moreover, fluid inclusion work conducted in the laboratory demonstrated the mineralogy of the area to be rich in iron, meaning it is capable of generating hydrogen gas in the presence of water.
This supports the company’s hydrogen generation hypothesis – that through a hydrolysis process, natural hydrogen is generated sub-surface, and is potentially able to flow from the source of its generation into other formations.
This update corroborates Gold Hydrogen’s earlier theories and supports the decision to twin the historic Ramsay Oil Bore 1 in mid-October.
The new well, Ramsay 1, aims to test for hydrogen in the upper Cambrian limestone, aligning with previous findings from the Ramsay Oil Bore 1 well.
