Following completion of drilling at the prospect, six miles north of the historic Model Dome helium field, raw gas was found and analysed, showing a calculated air-free gas composition of 8.8% in the Lyons formation.
The composition of the gas, in addition to nitrogen and carbon dioxide concentrations, was found to be similar to the average historic Model Dome analogue production, which represents one of the highest in-situ helium concentrations found both in the US and globally.
Commenting on the find, Trent Spry, Managing Director, CEO, Blue Star, said, “The whole Blue Star team is incredibly proud of this result. This result proves that gas is trapped in the Voyager prospect and is a strong validation of that interpretation and our prospect mapping.”
He added that historic well data in the Argo Galactica and Pegasus prospects has also been interpreted.
The Voyager prospect is associated with the Thatcher Dome area, an historic location for the Model Dome field helium processing facility.
Following the site’s abandonment in the 1920’s and 1930’s, Blue Star reinterpreted old well data, resulting in mapping of the Voyager prospect to unearth gas that had been missed in the area.
The water well drilling programme is an agreement between Blue Star and local ranch holders to drill three water wells in a data gathering mission to aid in defining helium prospects.
