Avanti Energy makes promising helium discovery in Montana


Avanti Energy has finished completions on the Flathead Cambrian Zone on its WNG 11-22 well in Greater Knappen, Montana, and has reported “major” helium discovery.

The firm on Wednesday (13th April) said its preliminary lab results show the gas composition of the Cambrian Zone to be 97.5% nitrogen, 1.1% helium, 1.1% methane and 0.3% carbon dioxide (CO2).

Based on such results, Avanti Energy has confirmed it is pursuing a facility design based on an inlet production rate of five million cubic feet of helium per day (mmcf/d) of raw gas, resulting in an estimated 55Mcf/d of net helium.

Chris Bakker, CEO of Avanti Energy, said, “The testing results of the WNG 11-22 well’s Flathead Cambrian zone is further evidence of the potential of Avanti’s Greater Knappen property.”
