maximum theoretical flow rate has increased under stimulation from 2.3 to 2.5 mmscfpd, so bugger all difference for the risk. This was the best section to stimulate and has produced a resource that has at best 1.4 bcf recoverable and will be sub-commercial within 4 years. GIP value would be around $1.6m for T/O evaluation on this section alone, pending further sections stimulation. remaining zones will need to produce a field of 20bcf minimum to make this a viable T/O target IMO and that will be highly unlikely, so vertical drills are unlikely to be viable here.
This is not even close to a Perth Basin analogue. It's a pup.
