Gold Hydrogen Ltd (ASX:GHY) has contracted Terrex to conduct a 2D regional seismic survey over its flagship Ramsay Project in South Australia, which is prospective for natural hydrogen and helium.
The survey will be flown over about 650 line kilometres within the PEL 687 licence on the Yorke Peninsula in South Australia with the aim of delineating an extensive and regionally-sized natural hydrogen and helium system, which was previously penetrated by the Ramsay 1 and 2 wells.
Terrex is one of Australia’s leading onshore seismic survey acquisition specialists. GHY has also contracted Total Seismic to assist with interpretation, project management and modelling of data from the survey.
To underpin geological model
“The seismic data will be the first modern regional seismic data set acquired over the Yorke Peninsula and will provide essential input into unravelling some of the geological complexities associated with the natural hydrogen and helium occurrences in the area,” Gold Hydrogen chief exploration advisor Frank Glass said.
“The seismic data, in combination with the historical and recent well data, will underpin the building of a consistent regional geological model and will assist with the selection of the drilling locations for the company’s next drilling campaign.
“With the ongoing support of Terrex and Total Seismic, I am confident the Ramsay 2D acquisition project will result in quality subsurface data, acquired safely and within all technical and environmental constraints.”
GHY expects to begin its second phase of exploration well testing in early July this year, scheduled to take about four weeks.
Stage 2 will involve the mobilisation and installation of a pump to lift formation water from each well through tubing to the surface with the intention to facilitate free gas flow to surface.
Gold Hydrogen says the testing program will aid in determining potential flow rates and accumulation metrics of the gas reservoirs at Ramsay, and that any detection of free hydrogen flowing to the surface would be “highly encouraging” for the future of the project.
