Pulsar Helium Reports Pressurised Gas Encounter at Jetstream #4 as Appraisal Drilling Advances

Core Viewpoint - Pulsar Helium Inc. has successfully commenced drilling the Jetstream 4 well, encountering pressurized gas, which indicates a strong gas reservoir and reinforces the geological model established from previous wells [3][5][8]. Drilling Operations - The Jetstream 4 well began drilling on November 9, 2025, and has reached a depth of 1,457 feet (444 meters) with a calculated bottom-hole pressure of approximately 674 psi [3][8]. - The well is located 0.4 miles (~600 meters) south of Jetstream 3 and 0.1 miles (~250 meters) north of Jetstream 1 at the Topaz helium project in Minnesota [7]. - Jetstream 4 has a planned total depth of approximately 3,000 feet (914 meters) and is being drilled using a coring method with a hole diameter of 3.8 inches (96 mm) [7][9]. Gas Encounter and Pressure Readings - Gas-bearing intervals were encountered at depths of approximately 1,187-1,277 feet (362-389 meters) and 1,327-1,437 feet (404-438 meters) [7][8]. - The bottom-hole pressure of 674 psi at 1,457 feet (444 meters) is a strong indicator of a pressurized reservoir, complementing the 960 psi recorded in Jetstream 3 [7][10]. Future Steps and Testing - Upon reaching total depth, both Jetstream 3 and Jetstream 4 will undergo comprehensive evaluations, including open-hole wireline logs and flow testing [10]. - Laboratory analysis will determine gas composition and helium concentrations, including testing for helium-3, which was previously detected in Jetstream 1 [10][11]. Project Overview - The Topaz project is located in northern Minnesota, where Pulsar holds exclusive leases and is the first mover in the area [11][15]. - Previous wells, including Jetstream 1 and Jetstream 2, have successfully penetrated helium-bearing reservoirs, with Jetstream 1 achieving a peak gas flow rate of approximately 1.3 million cubic feet per day with a sustained flow of 7-8% helium [11].
