Gold Hydrogen’s Ramsay 3 Well Flows 13,000 bbl a Day as Helium Phase 2 Looms
Key Takeaways
- Ramsay 3 Phase 1 delivered a Productivity Index of about 40 bbl/day/psi, roughly double Ramsay 1's derived figure of about 20, though the wells were tested under different conditions.
- Gross fluid rates reached up to 13,000 bbl/day with more than 25,000 bbl recovered between 10 and 30 September 2026, from a 105m perforated interval of the 180m Kulpara Dolomite.
- Helium concentrations, net pay and final flow rates are still undetermined, with gas and water samples under internal analysis and all Phase 1 data labelled preliminary.
- Phase 2 will move the 20,000 bbl/day ESP shallower for a stepped-rate test, with integrated results to feed a Contingent Resource assessment, though no timing has been given.
- Natural Hydrogen zone testing at Ramsay 3 follows helium testing, building a dual-commodity case alongside Ramsay 1 and 2 helium grades of about 19% and 20%.
Ramsay 3 Phase 1 helium flow test completed, Phase 2 next
Gold Hydrogen (ASX: GHY) has completed Phase 1 of helium flow testing at its Ramsay 3 well in PEL 687, Yorke Peninsula, South Australia, following its 14 September 2026 announcement. The headline numbers are a Productivity Index of approximately 40 bbl/day/psi, a gross fluid rate of up to 13,000 bbl/day and more than 25,000 bbl of fluid recovered.
Phase 1 ran from 10 September 2026 to 30 September 2026, including wellbore clean-up, with the Electrical Submersible Pump (ESP) set at approximately 730m. The company says the Productivity Index highlights strong permeability and deliverability in the 180m thick Kulpara Dolomite reservoir.
For you as an investor, that matters because deliverability is one of the first things a helium project needs to show. Still, the company stresses that the Phase 1 data are preliminary and remain under review and interpretation. Gas and water samples are currently undergoing internal analysis.

Phase 1 at a glance
The table below pulls together the key Phase 1 figures from the company’s technical disclosure.
| Metric | Result | Why it matters |
|---|---|---|
| Productivity Index | Approximately 40 bbl/day/psi | Company describes it as an indicator of strong deliverability and permeability |
| Gross fluid rate | Up to 13,000 bbl/day | Shows how much fluid and gas the lower interval delivered to surface |
| Fluid recovered | More than 25,000 bbl | Volume produced during Phase 1 |
| Perforation interval | 105m in Kulpara Dolomite, 500m to 800m depth | The section of the 180m gross target zone that was tested |
| Test dates | 10 to 30 September 2026 | Includes wellbore clean-up |
The source says insufficient information is presently available to determine net pay thickness, representative helium concentrations, or final flow rates. Final flow rates must wait until Phase 2 flow testing is complete.

Phase 2 targets the shallower helium zone
The 20,000 bbl/day capacity ESP is being repositioned shallower within the Kulpara Dolomite. Phase 2 is designed as a stepped-rate flow test, which means flow is stepped through different rates to see how the reservoir responds.
The company lists four areas of focus:
- Establishing additional reservoir deliverability data.
- Evaluating gas composition and helium concentrations.
- Determining flow rates under different operating conditions.
- Assessing the reservoir’s dynamic pressure and flow characteristics.
Rates of up to 20,000 bbl/day are expected, not demonstrated. That is a target for the test, not a result.
Ramsay 3 is the company’s larger-diameter scale-up well, which it says offers an opportunity to evaluate the Kulpara Dolomite under enhanced testing conditions. Once Phase 2 is complete, the integrated Phase 1 and Phase 2 results will be released to the market. The data and interpreted results will then be integrated into the geological model for Contingent Resource assessment. The announcement gives no timing for either step.
What is a Productivity Index, and why does it matter?
A Productivity Index (PI) measures how much fluid a well produces for each unit of pressure drawdown, in this case barrels per day per psi. A higher number generally means the rock lets fluid move more easily.
That is why the company links the figure to permeability and deliverability. For a helium project, a reservoir that flows readily is one input into whether a commercial case can be built, though it is only one input.
Ramsay 1 offers a comparison point. Its derived PI was approximately 20 bbl/day/psi at approximately 100 psi drawdown, with values of up to 34 bbl/day/psi also calculated. That test was constrained by a 2,000 bbl/day ESP, which the company says limited the rate, not the reservoir.
Ramsay 3 recorded approximately 40 bbl/day/psi. The wells were tested under different conditions, so the comparison is indicative only, and the figure does not by itself establish commercial viability.
Building on Ramsay 1 and Ramsay 2 results
Ramsay 3 follows earlier testing at the neighbouring wells. The company’s previously reported results include:
- Ramsay 1: sustained air-corrected helium concentrations of approximately 19%, with successful flow to surface, plus separation and purification trials using Quantum Technology purification equipment.
- Ramsay 2: sustained air-corrected helium concentrations of approximately 20% from the 180m Kulpara Dolomite interval, without purification.
- Reservoir continuity: dynamic testing at Ramsay 2 confirmed continuity of the helium-bearing Kulpara Dolomite approximately 500 metres from Ramsay 1.
The company describes these results as an increasingly substantial technical foundation for evaluating the Ramsay Helium Project, including the assessment of Contingent Resources. A Contingent Resource is a volume of resource that is potentially recoverable but not yet considered commercially mature.

Natural Hydrogen testing to follow at Ramsay 3
After helium testing, the company intends to test the Natural Hydrogen-bearing zones at Ramsay 3. That would allow it to keep evaluating both helium and Natural Hydrogen within the same scale-up well.
The Ramsay Project is being developed around a dual-commodity opportunity, with potential to generate value from both gases. McDonald said that with Phase 2 approaching, followed by Natural Hydrogen testing, “we believe this is an exciting period for Gold Hydrogen…”
The Phase 1 data are preliminary, and there is no certainty that the testing will achieve expected outcomes, that Contingent Resources can be booked, that an accelerated FEED or a Ramsay development will proceed, or that commercial viability can be established.
