So to put the potential of this sandstone area into perspective if my maths is correct:

A well at 850,000 scf/d at 12% is 102,000 scf/day or 102mcf/day of helium. Over a 345 day year of production that equates to 35190mcf/yr or 35.19mmcf/yr or 0.03519bcf/yr of helium from one well.

If you consider global helium usage is about 6bcf per year that's about 0.6% of global helium demand from only one well.

Or about supply of 0.6% of the US$13.21b helium market from one well. Or if my maths is right at an exchange rate of 0.65 that's about AUD$122m/yr of the global helium market from one well. That's at pricing of about US$2200/mcf noting Renergen would only ever get that sort of pricing rarely in the bulk spot market.
