Yeah,but what is the first piece of hardware to go down in an oil exploration/drilling?
Usually conducter pipe, I think. On land jobs, you hammer it into the ground. Here, I think the weight on the sea muck may set it. Then you jet it out or "wash" it out to get it deep enough to allow drilling. I don' think the initial conducter is cemented in.

Basically there is some drilling that is done and casing is set before setting the well head in place then the BOP is set later.
The actual drilling guys could probably give you a better response.

so they can dril a shallow hole before installing the BOP?
Yes. They don't need the BOPs until they get deep enough for the pressure gradient to matter. At ten feet below mud line, pressure is about the same as it is at mudline. Nothing is going to flow. At 5,000 feet, the pressure is a heck of a lot higher, so you need something capable of controlling the potential flow.

what is the diameter of the riser pipe we are seeing?
Posted on 6/2/10 at 10:59 am to JLTIGER
I thought I heard somewhere around 21" maybe but I could be wrong.

have a new riser with matching flange set up with about 15' of allthread for bolts. should be able to get within 15' of the flange before gushing oil pushes new riser away. once you get a few threaded, start to tighten them down and voila, problem solved.
Or have some multiple long finger type mechanisms that are hinged on the horizontal finger part. The LMRP is lowered, the spring loaded fingers hinge back at the top of the flange, then spring back under the flange. Ratchet down or maybe use a vise-grip clamping mechanism.

I turned my head and now the pipe is cut. Is that a ck line, it doesn't appear to be the 21 inch riser.

I think the C/K lines have already been cut. The lines alternate between the bolts. I think.

I've heard this theory a few times lately. I guess my only thought is that it is still an option if the LMRP solution does not work, and you were going to have to cut that riser to get the flange unbolted. So maybe it will happen.
I personally think it would be like trying to put the nozzle on your hose while it is going full blast, but smarter people then me think it could work.

Is that yellow thing an intake for a cooling system? A cuttings magnet? Does anyone know?
Posted on 6/2/10 at 11:22 am to JudgeHolden
I think that it is a bubble level and they are trying to find out if the thing is cutting straight. I don't see the bubble.
Posted on 6/2/10 at 11:23 am to JudgeHolden
havent seen it before, I was wondering the same thing

level, ball is on the left wall currently under some grime

thats why you use long runs of all-thread so you can thread them before the pressure gets too intense. i doubt it would work but it's something they should at least try.
to eliminate pressure you could also have an in-line valve above the new flange that is open, allowing oil to flow out of the riser while bolts are tightened, then once they have a solid connection close that puppy and start slurping.

Isn't that a bubble right in the center? Hard to tell with all the debris.
Edit: NM, I see it now on the left side.

not a bubble, small metal ball on the far left.

Could you push an air filled rise with a valve on the bottom that deep? Is the weight of the riser enough to counter-act the buoyancy? If a water filled riser is lowered then the hydrate crystal problem could reoccur.
Shady tree mechanic time. Could you mount a large mixing tool (think milkshake mixer) to the drilling line and break up the crystals?

They ought to somehow "crimp" the pipe and reduce the flow. Nothing that they set out to do has worked.
Like I said yesterday this probably wouldn't be a good idea. It would create pressure inside of the riser while they are trying to make the difficult final cut.
