mostly good news, page-3

Agreed, CW, you beat me to it because I was running some calculations before posting to confirm my initial thoughts.

This is pretty darn good news. Obviously the casing problems are disappointing but I know for a fact the same thing happened to Linc and as Carbon recently released, they had a similar problem. That's just a minor engineering hiccup (at a guess, related to the lateritized basalts in the tophole section that don't occur at Chinchilla). They'll figure it out.

The exciting news for me was the calorific value, particularly in light of the negative claims about Ergo's technology by some on this site. It was pointed out that air injection gives syngas with 1/8th the CV of natural gas, and oxygen injection about 1/4. The CV of natural gas is around 39MJ/m^3 (depending on composition) which means the CV of Kingaroy syngas ranges from 1/8th to 1/6th of natural gas - ie better than reasonably would be expected. The upper limit is about 18% the CV of natural gas, compared to 25% for oxygen injection. And Ergo is getting this from air!!

Of course we will need to wait and see if Cougar can maintain this level of production (obviously they need to control casing failures to do it), but this is a fantastic start.

Go the Cat, indeed!
