GP from memory wasn’t there also an over/ under pressure I forget which that they had to manage and needed beefed up equipment before going further down. I think they also confirmed it wasn’t the optimum location to test Cadeby hence the B1 well will check this formation again.

I think Rathlin originaly went for, and found, the gas. They've always known about Cadeby & it's potential which is why t they got permits in place for B1 at the same time as A2 (B2 was an add on I beleive) Basically they were always planning on drilling Cadeby in an optimal location for the potential reservoir even if the A2 well had only come up with gas.
Hi Rubey. Sorry for not being more explicit. I meant that there could still be significant oil in a well developed Cadeby formation in B-1. By that I don't mean just shows. However, my feeling is that if it had previously been really promising, wouldn't they have tried to test the Cadeby too?
GP, do you mean we might get a pleasant surprise because they might find oil in the Cadeby formation, or we might get a pleasant surprise because it might be a vertical drill? It's probably me, but I'm struggling to understand.
I've finally tracked down the source of the diagram in RBD's latest presentation (the one dated February '20 that shows B-1 as a vertical well and B-2 as a horizontal well). It's almost identical to figure 6 on page 12 in the technical section of Deloitte's June 2017 CPR. It's now very out of date as it predates the drilling of the A-2 well, although they've added a horizontal B-2 well to spice things up a bit. At the time, I they may have thought the Cadeby was still the primary WN objective, as it was before A-1 was drilled, and that it might be a "pinnacle reef". These are often seen in the Devonian of Western Canada, which is where Connaught, Rathlin's original parent company, are based. The English Zechstein / Cadeby and Kirkham Abbey Formations aren't usually developed in that way. But we might still get a pleasant surprise, one hopes.
Thanks GP. Not sure if it is a change in tack, or whether it's just a shortened version. Regarding WNA-2;
"encountered hydrocarbon shows within the secondary target Cadeby formation with an oil saturated core"
became;
"encountered oil shows in the Cadeby formation"
Whichever it is though, to be honest I like the reference to a core taken from the Cadeby formation from either WNA-1, WNA-2 or both being referred to as oil saturated.
A PS for Rubey. Did you see that i the 22 Sept RNS it said: "The WNA-1 well recovered oil saturated core and the WNA-2 well encountered oil shows in the Cadeby formation, which is expected to have better reservoir development at the WNB-1 location”
Do you think that’s a slight change of tack regarding which well had a Cadeby core?
All the best. GP
Hi Rovers66. In RBD’s 22 Sept RNS it said “drill the main borehole to a depth of approximately 2,000 metres. Completion is expected to take six to ten weeks” and I wondered why it would take so long. Perhaps a four week contingency has been included for unexpected results, I thought, or maybe for a well test. So I had another look at the latest presentation on the RBD website - which I think is dated February '20. It certainly shows B-1 as a vertical well, and B-2 as a horizontal well restricted to the Kirkham Abbey Formation. Speaking as a former geologist, I have to say that B-2 looks a bit odd for what was meant to be a further appraisal well (if drilled,and it looks more like a development well path to me. So I think this may be an old, somewhat schematic slide from Rathlin. For example, look at how the Cadeby Formation is shown; it certainly isn't drawn very accurately, well not geologically speaking. I also note that UJO no longer includes this slide in their own presentations. So, unless there is a more recent RBD presentation which shows B-2 as a vertical well, I'm inclined to take both the B-1 and B-2 well paths with a pinch of salt. Maybe I’ve got this wrong, so could someone please point me to an RNS where it says that B-1 will be drilled (more or less) vertically? Maybe it’s in a later presentation, but it still doesn't seem to be very clear from recent RNSs.
WNB-1 is a vertical well targeting the Cadeby formation - which is potentially much larger than the KA formation. By default this well will further appraise the higher KA formation in order to reach the Cadeby formation which is deeper.
WNB-2 will be a horizontal well through the Kirkham Abbey formation - and will be completed as a production well.
This has been stated by RBD repeatedly and is detailed in the latest investor presentation on the website. Whether they drill WNB-2 is another matter.
Recent half-Yr results said they plan to do an EWN at both WNA and WNB straight after the WNB-1 drill
Thats the work programme for the next 6 months.
Personally I reckon drill results won't be until early Dec. The earlier the results the worse the conclusions.
I agree Rubey. Plus 'leaks' of course. There may be a need to communicate via RNS to counter 'market speculation'.
This well is supposed to be vertical and the B2 a deviated lateral into the KA.
Manwell is on the money here with timing and they wil want to get on with the A2 EWT asap afterwards.
GP. My understanding is the planned horizontal drill will only be concerned with the Kirkham Abbey formation. I believe this drill (WNB-1) is targetting both Kirkham Abbey and Cadeby formations, so I assume it will be pretty much 'straight down'. As such I expect some feedback about the presence of oil around 15th November.
B.H....Yes it's ironic that the Bashers bible and Californian oil wells are both American creations. I had a laugh I admit, and can see why some on here like you and G.P think that some of the so called signs apply to me.; they do, but not many, and then only by default. I would like to think that what I post is constructive criticism where it is due, and not just for personal gain. Remember quite a few 'newbies' on this blog are akin to moths being drawn to a bright light. These 'moths' need to see both the Rampers versus other's comments, and be advised to do in-depth research on companies they are looking at investing in. Some companies need more research undertaken on them than others, as I am sure you will agree.
To think that there will be an early RNS this year regarding the outcome of the W>N project is delusional in my view. But hey ho we will soon know who is correct!
GP even if there is some sort of inclination it will be minor. B2 is the well that’s planned for a big build as it’s horizontal through the KA. You are correct in saying TD could more more than TVD. My +/- covers that as we don’t know exact depths, however I would expect the fm depths to be the same in the short distance from A2.
Oh persi.... don't try to change the subject. It won't work because we've all read the 'Bashers Bible' courtesy of GP
We don't give a hoot for your political peregrinations, your Californian crumbs or your Corallian cant. We are still laughing at the Easter gag.....laughing AT not WITH.
It's a good thing there is a seller or you'd look a right wally. When that stops this will..... boing
Is B-1 to be deviated, like some of the previous wells? If so, the measured / drilled well depth to TD could be significantly more than 2100 metres vertically. It might therefore be slightly slower drilling, and take a bit longer to drill, hence the suggested 10 weeks. And we don't know how many cores they may need to take in the event of success. So Rathlin's time estimate may be erring on the cautious side.
B.H.......I guess you like all the companies and investors in Californian oil fields are desperately hoping for a Trump win in the upcoming U.S Presidential elections. An Uncle Joe win and it's green fields everywhere, with wind farms replacing nodding donkeys. I think a dilemma for many who have a vote.
VOTE TRUMP X
Thanks Manwell! Persi sounding a little desperate with his ‘Easter’ LOL
Best return to California etc
Or not.....
A heat haze and twitter gossip will be a big clue whats going on well be for EWT results are confirmed
Last well duration was 26th April to 9th June, just over 6 weeks. If drilling +/- 2100 metres vertically takes 10 weeks I’ll eat my hat. We will at the very least get drilling, logging & core results prior to Xmas.
"Completion is expected to take six to ten weeks. Once completed, the drilling rig will be demobilised from the site over a period of approximately one week".
Between New Year and Easter before any results will be known, and that's without any 'hiccups' along the way!
They need to spud ASAP as 6/8 weeks puts us mid/late November. Doesn’t leave us much time then to rig down & de-mob the rig, then rig up & welltest before Xmas.
Looks like they’re already to go, just surprised UJO not moved at same level this morning ? Hopefully we should have some news for WN before Xmas
Glad I topped up. Gone NT to buy
some chunky buys and maybe the seller has now paused - can't get a price on even 1k - 5575 to sell though so something is afoot
They have my permission to get going.
Over
