Avanti Energy has completed an acidisation and and clean-up process of the Flathead Cambrian zone on its WNG 11-22 well, after which the well peaked a flow rate of over 4 mmcf/d for six days. Preliminary lab results of the Cambrian Zone indicate a helium concentration of 1.1% and 97.5% nitrogen. Based on these results, the Company is pursuing a small facility design based on an inlet production rate of 5 mmcf/d of raw gas, resulting in an estimated 55 mcf/d of net helium (~20 liquid ISOs of helium per annum). There are no details on the reserve potential and the size of the structure appears to be fairly small.
