Highlights
- Higher Helium Concentration: New samples from the State-16 well show a 2.17% helium concentration, up from the previous 1.65% average.
- Encouraging Reservoir Connectivity: Well head pressure of 10 psig — the highest recorded to date — suggests positive long-term flow potential.
- Ongoing Analysis at Jackson-31: Gas samples from the nearby Jackson-31 well are still under evaluation, with results pending.
Helium One Global (LSE:HE1), the leading helium explorer in Tanzania with a 50% stake in the Galactica-Pegasus Project in Colorado, has reported a significant increase in helium concentration at its State-16 well. The update follows an announcement by Blue Star Helium (ASX:BNL), the project operator, and highlights promising progress for the development.
Helium Concentration Rises to 2.17%
Newly collected gas samples from the State-16 well show an uncorrected helium concentration of 2.17%, representing a material increase from the previous 1.65% average. When previously adjusted for air contamination, helium levels had reached 1.90%, but the latest results suggest a natural enrichment of the reservoir over time.
The latest gas composition breakdown includes:
- 2.17% helium (up from 1.65%)
- 36.26% nitrogen (previously 28.05%)
- 61.56% carbon dioxide (down from 70.29%)
The rise in helium levels is attributed to natural reservoir equilibration near the well bore, an encouraging sign for future production capacity.
Positive Pressure Signals Flow Potential
Alongside the improved helium concentration, well head pressure was recorded at 10 psig, the highest level observed at State-16 so far. This pressure increase indicates significant reservoir connectivity, suggesting that the well could sustain long-term, commercially viable flow rates.
The well is already completed for tie-in to production facilities, positioning the project for a smooth transition into production once final testing is complete.
Awaiting Jackson-31 Results
Helium One and Blue Star are continuing their evaluation of the nearby Jackson-31 well, with gas samples still under analysis. Results from this well could provide further insights into the broader reservoir’s helium potential and support strategic development decisions.
