Building on WhichWayNow's post (Sat 17:39) i.e. :

"Discovery of Oil column
Geology analogous to Lancaster
Expectation of 935million barrels, one of the biggest recent discoveries in U.K. waters
Suspended as a future producer subject to a workover at that time to clean the well up
TL moves to Lincoln for appraisal well "

I would add:

Issues analogous with that experienced at Halifax, but with time could be resolved
oil type confirmed to be same as Lincoln
pressure gauges successfully engaged (to validate continuation of Lincoln and the rest of the field)
the large fractures encountered (location and size) tie in with seismic (validating model)

The upshot is I believe, if there is enough data from the drill to allocate 2C resources via a CPR then the well is a Rsuccess and hopefully lots of useful data and lessons learnt can be utilised on the next drills. Lets hope the expected RNS confirms most of the above. Fingers Crossed. GLA and ATB

Hi adoubleuk,
Don't know why my reply to you disappeared, must be a glitch with this new website (why do these people keep changing things!!!!!!). Anyway there was nothing contentious in my reply as you know, I was just thanking you for taking the time to give me the benefit of your experience, which many on this site appreciate. I also copied a reply I got from another helpful poster (Linz22) from the other site which complimented your response i.e.

"creating a wellbore in fractured basement is problematic due to instability, by definition, ie. it's heavily fractured. Furthermore, they're using a brine circulation system, heavilly laden with LCM, which means they'll be drilling the reservoir section underbalanced, rendering it even more unstable. CT drilling (with a bit and downhole motor on coil tubing) is most suitable for tight access in more stable wellbores, eg. workovers in previously lined production wells, not long-reach exploration wells, vertical, dog-legged or otherwise. And, I think that's probably what you meant by being advantageous over "open hole" drilling..?"

Lets hope a discovery is confirmed at WD, and its then just a question of how to get the oil flowing without clogging it up (if this is the reason). As always, necessity is the mother of invention and I'm sure great minds are working on this as we speak.
I vote for WhichWayNow to head the PR department for Hurricane!!! ATB

Anyone know how Lundin carried out their successful horizontal drilling in the Rolvsnes fractured basement discovery and how this compares with the method Hurricane have used/adopted, especially wrt mud type/weight utilised etc?

However, I expect the rock type/pressures etc are not the same so maybe not a straight comparison.

I hope both companies are collaborating on their experiences to date (good and bad)for their mutual benefit.

Just out of interest could CT drilling for both the vertical and horizontal sections have been possible in fractured granite and would this have advantages over open hole drilling? Thanks in advance. ATB

I'll second that Albi1, I think you speak for very many on here.

What a journey so far!

Lets hope it continues for some time yet, although I will be happy if we are 'interupted' for the right reasons. ATB LTH's.

Anyone know where, along the well the DST is likely to be taken, or will a number be taken along the length of the well, maybe to determine the flow from different fractures etc? Thanks in advance. ATB

A useful bit of research in the following link:

Gotti, Thanks for adding the presentation link.

Mitch stated that SQZ's contribution to final decommissioning of the present assets will be 15%. Anybody got an idea of the likely 'full' cost of decommissioning the present assets?? ball park even, just to get a handle on it?

Thanks in advance. ATB

Don't know if this has been posted before but while we are waiting attached is a very interesting paper produced by AEA for the HSE wrt FSPO turrets/swivel systems etc.

"It is very difficult to imagine that Bluewater’s engineers did not consider the possibility that modification might be required to the winch capacity resulting from the larger buoy and increased operating depth. If they did not crass stupidity."

Agreed, but mistakes happen in real life. A thorough independent checking procedure and certification process in place will in most cases mitigate gross errors. I'm sure there were checks carried out, but something went wrong, and we may never know the full facts.

Anyway, lessons will have been learnt and the next hook up attempt will hopefully be successful as originally anticipated.

In some literature I breezed through recently it stated that hook up of the buoy in a FSPO should take about 3 hours. Dr T in previous interviews stated that a 6 hour window is required, and IMO it would appear that he sated 6 hours as a conservative figure i.e. he expected it to be done quicker. ATB LTH's.

As previously infered by snaggletooth I would expect that the replacement rope will have a higher load carrying capacity than the ropes already used, for obvious reasons. Generally speaking temporary works design loads (which is what we are looking at) are normally 1.5 times the working load. The working load to be resisted by the rope will also need to be re verified and independently checked before any replacement rope is procured. None of us here know whether the rope was defective/inadequate or the design loads were miscalculated. However, I'm sure all the necessary analysis/checks will be done thoroughly again and double checked before a new rope is procured (and hopefully certified by Chartered Engineers).

On MT it looks like she is lining up for another go. Fingers crossed! ATB all LTH'S

Looks like she is moving again???????????

Ohe main reasons for so many of the existing wells becoming redundant is apparently due to lack of maintenance and well bore collapse or clogging up of the production stem with sand.
ZEN will be fully aware of all the issues now and I fully expect them to be able to design these out by utilising the most up to date methods.
For information, attached below are a couple of useful links showing the non oil professionals like myself how pipework is installed and cemented in place and t screens/packing methods available to ensure the wells flow.

Great news today which removes much of the concern about funding operations going forward.
-Funding in place without dilution (well played Andrea!).
-Full ownership of 3 rigs.
-Experienced Geotech Specialist now in place to ensure a properly targeted and prioritised programme of work
-Oil in place
Soon to be drilling in earnest when the 100 and 260 rigs get to site. All to play for here

Mudstud, Thanks for the correction. Yes it is apples and oranges with the comparisons but in simplistic terms there is still massive potential 'if' they can get the oil out. The oil is there, a lot of it, but it has so far proved not so easy to get it out. Drilling new wells will surely make a significant difference. The challenge now as everyone knows is getting the oil out before the money does! ATB, Mally
