Southern Rukwa ESP Test — Early Signals, Big Potential16 Feb 2026 21:51
The RNS today confirms that Helium One’s early-stage Electrical Submersible Pump test at ITW-1 has been successfully completed, producing up to 16,400 barrels of fluid per day, a six-fold increase over natural flow during the 2024 Extended Well Test. Helium concentrations were sustained at 5.4%, peaking at 9.2%, demonstrating that helium is consistently coming to surface.
Importantly, this was an initial production validation, not full commercial production. The ESP ran continuously for over 450 hours with zero downtime, proving both operational reliability and manageable water handling at surface. Reservoir pressures re-pressurised quickly after shut-in, indicating strong reservoir support and connectivity.
The next stages will involve further ESP optimisation, additional testing, and potentially new wells to better understand helium distribution, gas-water ratios, and Basement/fracture system performance. Different flow rates over different timescales will provide more granular data to guide development decisions and partner engagement.
This RNS is extremely positive: the well is producing reliably, the ESP has exceeded expectations, and the project is now positioned for a strategic farmout to bring in an industry partner. For investors, this early-stage success reduces operational risk, validates the helium system, and sets the stage for commercial development.
The message is clear: the southern Rukwa project is advancing, the ESP program is continuing, and Helium One is steadily moving from exploration towards a scalable helium production operation.
