RE: Appraisal well23 Nov 2020 10:29
Some investors, or perhaps our non-investing commentators, will only see today’s RNS in a negative light. My take on it from a geologist’s rather speculative point of view is a bit more favourable. I think the B-1 well may have been deviated to the east to penetrate the slope towards the Southern Gas Basin. This would have made it a very ambitious step-out / appraisal well. It’s therefore good to know that the Kirkham Abbey reservoir extends this far. I would have expected both objectives to be much thinner here than at the A site, just as they are in the offshore area. In my view there’s no good reason to assume that the sidetrack, which is presumably designed to look at the shelf area again, won’t work for the Kirkham Abbey. I suspect it will probably be drilled in the general direction of the WN-1 and A-2 wells, but I’ve seen no published evidence for this. Regarding the Cadeby, the RNS says “The secondary target ..... contained insufficient reservoir development at this location”. This fits in with my slope hypothesis and, although disappointing, it’s not a great surprise in the geological context. RBD also say “The sidetrack will also provide an additional penetration into the Cadeby, which Reabold believes remains a valid target in this location” . This doesn’t appear in UJO’s RNS and I don’t know if it means anything, but RBD’s and UJO’s RNSs usually say much the same thing. So it’s possible UJO now has a slightly different view of Cadeby prospectivity since so little was seen in the B-1 well, let alone a reef, at what was meant to be a favourable location. I guess the jury has yet to decide on the Cadbey, IMO of course.
