Gold Hydrogen Begins Ramsay Flow Testing Campaign Ahead of Commercial Assessment
Gold Hydrogen has announced that mobilisation is underway for its 2026 Ramsay flow testing campaign in South Australia, with testing expected to commence within approximately one week across the Ramsay 1, Ramsay 2 and Ramsay 3 wells. The campaign represents the next major step in evaluating the commercial potential of the company's natural hydrogen and helium discovery.
Site preparation, civil works and mobilisation of testing equipment are well advanced, while key regulatory approvals have already been secured. Gold Hydrogen expects the SWS Rig 04 workover rig to arrive at the Ramsay 1 well shortly, after which flow testing will begin using significantly higher-capacity electric submersible pumps than those employed during previous testing.
The Ramsay 1 test will target helium-bearing formations, collecting flow rate, pressure, sampling and laboratory data. During the company's 2024 testing program, Ramsay 1 returned helium purities of up to 36.9%, although flow rates were constrained by the use of a 180-barrel-per-day mechanical pump. The new campaign will utilise a 2,000-barrel-per-day electric submersible pump for both Ramsay 1 and Ramsay 2, while Ramsay 3 will be tested using a substantially larger 20,000-barrel-per-day pump designed specifically for its larger wellbore.
Gold Hydrogen said previous drilling and evaluation work has identified air-corrected natural hydrogen purities of up to 97% and helium purities of up to 36.9%, supporting the continuity of hydrogen- and helium-bearing reservoirs across the Ramsay Project. The upcoming campaign is intended to measure sustained flow rates from these formations and generate the engineering and reservoir data required for commercial assessment.
According to the company, successful completion of the testing program could support the booking of contingent resources, future field development planning and Front-End Engineering Design (FEED) activities. Gold Hydrogen also noted that a recent commercial assessment completed by Worley has identified potential pathways toward accelerated commercialisation, particularly for helium production.
