Pulsar Helium’s Jetstream #1 well achieves triple 2024 flow rates, validating Topaz project’s global significance and confirming exceptional reservoir productivity.
Pulsar Helium Inc., a specialist in helium project development, has released highly encouraging flow test results from the Jetstream #1 appraisal well at its Topaz helium project in Minnesota, USA. The results mark a major step forward, with natural flow rates now more than three times higher than those recorded in 2024.
On August 15, 2025, Jetstream #1 achieved a peak natural flow rate of approximately 501 thousand cubic feet per day (Mcf/d) on a 38/64-inch choke at around 30 pounds per square inch (psi) wellhead pressure. Importantly, this was achieved without the use of stimulation or compression equipment, and no formation water was detected. The well has consistently produced dry gas, further confirming the quality of the reservoir.
This represents a substantial improvement compared to April 2024, when the same well delivered ~150 Mcf/d at similar pressure conditions. At that time, helium concentrations ranged between 8.7% and 14.5%. The current results, therefore, demonstrate not only the effectiveness of the well’s deepening to 5,100 feet but also the productivity of the helium-bearing formation.
According to President & CEO Thomas Abraham-James, the test results validate the company’s geological model and significantly de-risk the Topaz project. He emphasized that the ability to achieve such strong natural flows confirms the reservoir’s exceptional recharge capacity and positions Topaz as one of the leading primary helium projects globally. Abraham-James noted that these outcomes build on earlier confirmation of a “major helium discovery” and represent the beginning of unlocking the project’s full potential.
In addition to peak flows, Jetstream #1 maintained stable sustained rates of 150–300 Mcf/d for 12–18 hours using smaller choke sizes, with rapid pressure recovery after testing. This consistency highlights the strength and stability of the reservoir, which is crucial for long-term production planning.
Looking ahead, Pulsar is preparing compression-assisted flow tests at Jetstream #1 to evaluate maximum deliverability. Previous compression tests in 2024 boosted flow to ~821 Mcf/d, and similar or higher results are expected this time. Such tests will provide valuable data for designing production facilities and advancing the Topaz project toward commercial development.
After completing current testing, all equipment will be relocated to Jetstream #2 for comparable assessment, with further updates on helium concentrations and gas composition anticipated soon. The company believes these results strongly reinforce Topaz’s role as a potentially world-class source of primary helium at a time when global demand for secure helium supply continues to grow.
