Helix has measured up to 55% NatH2 in Montana
Helix’s Clink #1 well at the Ingomar Dome prospect in Montana delivered promising
NatH2 results with the Flathead formation, which yielded 55.2% hydrogen in drilling
mud. During drilling, the mud interacts with the formation, allowing formation
materials to mix into the mud and vice versa. These materials are detected at the
surface using a mass spectrometer as the mud returns from the hole. While the
system is designed to capture formation gas or fluid, insufficient gas was recovered,
likely due to the mud restricting its flow. However, hydrogen was detected in
significant concentrations, spiking dramatically upon reaching the Flathead
formation, rather than increasing gradually with depth. Helix plans to revisit these
horizons possibly with an acid treatment, building on the unexpected hydrogen
results. Helix had thought that NatH2 may be present as another well drilled in
northern Montana saw 26% helium in the mud system. Also all the geological
conditions for NatH2 generation are present: ultramafic (high iron content) rock and
the Wyoming Craton (oldest rock in North America).
