edgar222 re Targets
View of someone who has 35 years oil experience including onboard Stena Icemax drilling offshore poster Coman. I noted he stopped posting here when we spudded Perseverance 1 - for what it's worth I re-post a valuable view given by Coman headed under
"Duster or Winner Timeline" August 2020
I have a lot of experience of drilling these types of wells with these types of rigs. I have no knowledge of the actual well design but looking at the stratigraphic column and the timing of 30-45 days (the difference i suspect relates to whether the well is dry or a success)."Based on the outline well plan that was shown I think on one of the Simon Potter presentations it should take approximately 10 days to get to the 1st reservoir target.
A typical operational outline would be;
1) Load up with all materials and sail to location, I assume the clock starts when the rig is on location.
2) Position the rig and drill the riserless top hole section. This will involve either jetting in typically +/- 80m of 36" conductor or drilling 36" x 42" hole and then running and cementing the conductor. Then drill 26" hole to typically +/- 800m below the seabed and run and cement either 22" or 20" casing. Depending on whether the conductor is jetted or cemented all this should take +/- 7 days.
3) Run and test BOPs on the wellhead. As the rig is set up for managed pressure drilling (MPD) this involves running and rigging up additional equipment so will probably take +/- 5 days
4) Drill 17.1/2" hole to above the top reservoir and run and cement 13.5/8" casing. They may run some wireline logs before the casing. Approx timing for this could be +/- 5 days.
5) Drill 12.1/4" through the reservoir to well TD. Typically an exploration well would be a vertical hole and based on the quoted target depth of 4,822 metres and the photo on page 11 that is the case here. It may take 7 or 8 days to drill this section depending on ROP and if they need to use the MPD system. As soon as they start drilling through the reservoir they will see the real-time logging while drilling (LWD) data and have a very good idea if they are in the success case scenario or not....everyone on the rig will know!
6) Perform wireline logging. In the failure case, this may only take 1 or 2 days. In the success case, this could take up to 10 days. From what i can see there is no plan to do a drill stem test (DST) to determine reservoir properties and flow rates etc however there are wireline logging tools now available where you can get a lot of this data anyway. It also makes more sense to do a DST on an appraisal well rather than incur significant additional costs on an exploration well to be ready to perform a DST and then not do it. They will know for sure at this stage if it is a success or not and could make an announcement shortly after. On recent projects, I have been on the companies have made announcements within a couple of weeks of logging...Continued

Proselenes,
Thank you for your advice but the wrong board...I appreciate I do really, will return your favour with a big Glasgow kiss! lol
Today STENA ICEMAX 14 days since Spud commenced on Sunday 20th December 6.30 am Perseverance 1 - anticipated 45 - 60 days to complete.
The following I re-post once again the view from someone if you are new we were lucky to have on board, namely poster Coman. A 30 year experienced in offshore drilling industry engineer who also has a degree in Petroleum Engineering. He is familiar with our type of drilling rig, been lucky enough to work on both the Maersk Viking and the Stena Icemax, Therefore, as I see it if you are going to ask a question he is well qualified to explain drilling process on STENA ICEMAX. He obligingly said he is happy to offer any operational insight where he can...
Coman views
"On Page 11 of one of the corporate presentations shows the various targets, the top one being the Albian and looks to be at +/- 1750m. The rest of the targets look to be from +/- 2500m and below. That means they must be drilling the 16-1/2" hole through the top Albian target and setting the 13-3/8" casing between the 1st and 2nd target. Thereafter looks like they plan to drill 12-1/4" through the rest of the targets - if they can.
Some of the timings in the EIA don't seem realistic - eg 1 day to run BOPs, part of that is done off the critical path due to the dual derrick set up on the Icemax but I still don't think 1 day is possible especially with the MPD kit to hook up. However based on the well plan in the EIA if they don't encounter any problems I'd say they should easily be in the 1st reservoir within 10-15 days
The MPD package helps manage the well problems associated with drilling these formations. So assuming they are going to have that system completely set up and utilised it would probably add a couple of days overall to the time taken to reach the 1st reservoir.
BPC will most likely have the Schlumberger tools available to perform a mini DST on wireline which gives a lot of the same information. A mini DST also does a pressure drawdown followed by a pressure build-up. Very few companies now do a DST on an exploration well due to the costs associated with having the equipment available and then not doing the test if the well is a duster. Having the tools available for a mini DST won't cost much more than having the normal wireline tool package available and a mini DST can be done in a couple of days as opposed to potentially a couple of weeks or more for a full DST. In a well like this, a mini DST also has the advantage of being run over several of the different zones
My experience is all in Drilling however from what I know of production using an FPSO in the water death and environment makes perfect sense, produced oil would be pumped from the FPSO to an Oil tanker to be taken to a refinery so what has been quoted seems perfectly logical
*Thanks, COMAN for your various views during November & December 2020, it all help everyone form our own opinion.

THANKS, COMAN.
Below a post from our resident offshore drillship experience poster CoMan, subject of keeping it confidential 3rd Oct 2020
"normally everyone onboard who has access to the screens on the rig that show the realtime logging while drilling data has to sign a confidentiality agreement. Obviously, the BPC team in town will also have realtime access to all that data as will some of the 3rd party service company providers (Halliburton). The logging while drilling tools are placed just above the bit while drilling so very quickly the team will have a good idea what they have drilled and whether it contains oil or water. No matter how hard the company tries to prevent this information from getting out, it's very difficult to do so. The wireline logging which is performed after the section has been drilled records a lot of the same information but in much more detail with far better resolution so is more accurate - which is why a company would wait until they have that information before making any announcement regarding the success or otherwise of the well "
