Pulsar Helium announced a major milestone at its flagship Topaz Project in Minnesota.
The Jetstream #3 well commenced drilling on Oct. 17 and has encountered pressurized gas with a calculated bottom-hole pressure of approximately 960 psi, underscoring a highly charged gas reservoir.
This development marks a significant step forward in the ongoing drilling campaign, building on the success of the earlier Jetstream #1 and #2 wells and confirming the continuity of the helium-rich system.
Jetstream #3 is located 0.6 miles northeast of Jetstream #1 at the Topaz helium project east of Babbitt.
Jetstream #3 intersected two gas-bearing intervals at approximately 1,717 and 2,036 feet depth, with bottom-hole pressure estimated at 960 psi at 2,167 feet.
This strong pressure reading indicates a robust, pressurized reservoir at the well location, a major validation of the Topaz field’s potential.
For comparison, Jetstream #1 had a bottom hole pressure of 185 psi when drilled in 2024, and Jetstream #2 had a bottom hole pressure of 205 psi when drilled in 2025.
Jetstream #3 has a planned total depth of 3,500 feet and is being drilled using the coring method with a hole diameter of 3.8 inches.
Drilling personnel observed gas bubbling in the drilling mud returns at surface during pipe connections. This indicates an active gas influx from the formation while drilling is underway.
Thomas Abraham-James,President and CEO said, “Encountering such strong gas pressure at Jetstream #3 is extremely encouraging for our team. A near-1,000 psi bottom-hole pressure suggests we have a highly charged reservoir at this location.
“This outcome not only validates the geological model we built from Jetstream #1 and #2, but also boosts our confidence as we continue drilling and begin the testing phase. We will proceed carefully to collect comprehensive data, including gas samples for lab analysis, to fully understand the reservoir’s characteristics. It’s an exciting milestone for Pulsar as we advance Topaz toward becoming a leading primary helium project in North America.”
Once Jetstream #3 reaches total depth, Pulsar will initiate a comprehensive downhole evaluation program, including a suite of openhole wireline logs, flow testing and pressure build-up analysis.
Concurrent with field testing, core and gas samples from Jetstream #3 will undergo thorough laboratory analysis. The lab program will determine the gas composition and exact helium content of the samples.
The analysis will include assays for helium-3, a rare isotope of helium, given that helium-3 was previously detected in the Topaz reservoir at notable levels.
