While the result is interesting, I don't understand the rally in SP - all the new well has done is to confirm the result of the original Ramsay bore which I guess was the objective. What we really need to know is whether the H2 flows to surface, what pressure and whether it is continuous. The Helium again is interesting at 3% but you need to produce a lot of gas (most of which is Nitrogen) to get a volume that would be commercially viable. Bayu Undan field has only 0.1% He in the natural gas but it has produced > 3 Tcf so the sales volume of He is significant. Hard to see how you can trap large volumes in the fracture network unless they extend for 10's of km in which case you need a lot of wells.

Early days for GHY. It all comes down to how it flows and what connected volume is there.
