Pulsar's Jetstream No. 4 well hits pressurized gas

Executive Summary

• Pulsar Helium Inc. reports a pressurized gas encounter at Jetstream No. 4, with a calculated bottom-hole pressure of approximately 674 psi at a depth of 1,457 feet (444 metres).
• The well has intersected gas-bearing intervals at two distinct depths and continues drilling toward a total depth of 3,000 feet (914 metres), maintaining a 100% success rate for gas encounters across the Jetstream program.
• Upon reaching total depth, both Jetstream No. 3 and No. 4 will undergo simultaneous comprehensive evaluation, including wireline logging, flow testing, and laboratory analysis for helium-3 isotopes.

Key Details

• Well Status: Jetstream No. 4 commenced drilling on Nov. 9 and is currently at 1,457 feet (444 metres), advancing toward a planned total depth of 3,000 feet (914 metres).
• Pressure Reading: Calculated bottom-hole pressure is approximately 674 psi at 1,457 feet; this is subject to change as the hole is deepened.
• Gas Intervals:
  • Interval 1: 1,187 to 1,277 feet (362 to 389 metres).
  • Interval 2: 1,327 to 1,437 feet (404 to 438 metres).
• Drilling Method: Continuous HQ core drilling with a hole diameter of 3.8 inches (96 mm) and large-diameter core (~63.5 mm) to maximize sample recovery.
• Observations: Visible gas bubbling in drilling mud returns was observed during pipe connections, indicating active gas influx.
• Future Testing Plan:
  • Simultaneous testing of Jetstream No. 3 and No. 4 to reduce mobilization costs.
  • Suite of open-hole wireline logs for geological and petrophysical data.
  • Optical televiewer to image wellbore wall geology.
  • Controlled flow-testing and pressure build-up program to measure well deliverability.
  • Laboratory analysis of core and gas samples to determine gas composition, helium concentrations, and helium-3 isotope levels.
• Contextual Data (Jetstream No. 3): Reached total depth on Nov. 7 with a calculated bottom-hole pressure of approximately 960 psi.
• Contextual Data (Jetstream No. 1): Reached total depth of 5,100 feet in Jan 2025; August 2025 flow test showed peak gas flow of ~1.3 million cubic feet per day with 7-8% helium (as helium-4) and confirmed measurable helium-3.
• Project Location: Topaz helium project, northern Minnesota, USA.

Notable Quotes

• "Encountering another zone of pressurized gas at Jetstream No. 4 is a highly encouraging continuation of what we are seeing across the field. A [approximately] 674-pound-per-square-inch pressure reading at this relatively shallow depth reinforces the strength of the reservoir and further validates the geological model built from the earlier Jetstream wells." — Thomas Abraham-James, President and CEO
