[QUOTE=rlanasa;34137]Nothing will blow material 60 feet through water. You might displace water for some distance but not misshaped projectiles through it. If we had an explosion that displaced the water the ROV would thrown with it and we would lose the shot. Consider what happens when a cameraman falls…

That must mean the guys on DWH that testified the well blew a 20" stream through the derrick some 200’ or more were lying then. You still comment on things not on the BP website?
"BP stopped Development Driller II progress to prepare the DDII BOP to be put on the DWH blow out well."
More likely they stopped to prevent communication between a formation DDII was drilling through and a formation DWM blow out ops were pumping to.
The coefficient of friction though water is much great than air. Try to throw a brick underwater next time you are in the pool. Try the same thing in your yard.

[QUOTE=CPTdrillersails;34134]CM1 - Thanks for all your info. I probably should let people know I’m a geologist (and a cpt driller) and have worked on just about every kind of drilling EXCEPT for petroleum. You guys lingo is definitely specific. Could you describe hot-stabbing and blinds? If you looked at the bp guys video he describes this LMRP cap process and I’m trying to get a handle on that. My understanding is they are going to cut the riser off just above the BOP and install this seal across that surface. I don’t understand why they don’t run a (vented) tapered tool into the riser. Or at least I didn’t understand until I found out that they also have drill rod stuck in the riser, so they have to essentially cut 2 steel pipes, the riser and the drill rod “rattling” around inside it, when they get done with that, they will have a pipe within a pipe, both cut off flush both exploding with oil, sand, gas, methane hydrate, rock debris, metal shards, etc… Still, a tool could be fabricated that would fit between the riser and drill rod, or even [I]over[/I] the riser. What do you think?
Not a happy situation.[/QUOTE] A hot stab is simply stabbing a well control device over live pressure or possible live pressure. Blinds are rams that when closed will not allow flow through them. picture a valve with two rods pushing two have gates that overlap each other. The only reason I can see the DDII getting over the well is to run down with a set of hydraulic shears & sutting the ram & joint of pipe then maybe pulling the riser up or at least out of the way. The probllem with Settles statement is they evidently sent weight down, possibly with the DDII & smashed the riser on top of the stack before they started pumping Wednesday afternoon.
By doing this they constricted flow to where they could probably catch up with rate easier, but it also makes it darn near impossible to get back over the well with wht’s left. that’s the difference between a guy like that & a working hand. Maybe they know something I don’t, I kinda doubt it though. It doesn’t look like anything is doable with that mess & the well flowing at that depth. Remember that rig is DP & has to be completely stationary to even make a stab in static conditions with an ROV doing the guiding. Imagine the working conditions with 40k blowing at you.

Do us all a favor & take two bricks & smash them together with your head in between.

I’m sorry for the people who died in airplane crashes but a plane crash could never cause such damages and hazards for millions of people/animals and for environnement for YEARS.
I don’t think it is wise or fair to compare the two things, with all respect for all the people working for oil industry.
[QUOTE=company man 1;34126]goedude are you in directional drilling or a geologist, mud man, etc.?[/QUOTE]
I’m just an oil geologist who is looking at a train wreck for his industry. We’re all feeling BP’s pain, now. The growing drilling moratorium is going to put a lot of my colleagues out of work in the coming months. I stumbled on this site during a google search and found the discussion to be enlightening, despite the occasional rants. So long as enough posters keep saying something interesting I’ll keep following. And if something comes up that I think I can answer, I’ll chime in.
I feel a little like a rubbernecker on the highway slowing down to look at a wreck. I know in my mind I should just look straight ahead and drive forward, but I can’t help but look. I can’t wait till they kill this thing so I can stop keeping the video feed in the corner of my screen and being mesmerized every time something happens. It feels a little like watching Apollo 13 and they are down to using duct tape to put a square filter in a round hole. Failure is not an option.

Bob, you said exactly what I was thinking. Remember they said they lost, what 3000 barrels of mud to circulation when they hit a thief zone that was within 5000 ft or so of the seafloor. I believe that was said in this morning’s hearings.
To geo… it feels a lot like Apollo 13 to me also… and also another one “up there” that begins with a “C” I’m retired now by 18 months, but it “feels” the same, and my heart is grieved for those that have been lost, and those effected. Good people, some poor judgment, and some critical hardware that failed… couple that with a lot of energy and you have a real tar ball…
To rlanasa, I am not overly impressed with PhD’s in tactical situations. For the record I am an experimental nuclear physicist, some of the best ideas when under fire, come from the line. The PhD’s are best performing the refinements to make those ideas implement technically, and the managers so that the solutions implement seamlessly in time and space… When I’m in a firefight I know the kind of person I want next to me. Been there, done that over a 38 year career.
Let’s be nice and I would be honored if you cut CM1 some slack.
I didn’t want to sound so harsh the other day & you probably got into this thing late in the game so just to let you know, I came in here asking questions & seeking info just like you. I happen to have worked in these conditions & have the background to understand just about everything they are addressing. I never imagined I would be doing this stuff a few weeks ago, but there is so much ignorance out there being pumped by highy paid so called experts that have never set foot on a rig when, I address these things it is from a position of trying to protect my business & set the record straight, while informing people who are wanting to learn more & therefore become a friend to this industry & understand better the challenges that we face everyday. I cannot & will not excuse the arrogance, incompetence, & lack of communication that have become evident leading up to this disaster & ever since. I find BP to be relentless in their arrogant I’m smarter than you attitude. This is a perfect example of exactly what was the MAIN cause of this adccident.[QUOTE=geodude;34155]I’m just an oil geologist who is looking at a train wreck for his industry.

[QUOTE=rlanasa;34043]OilDrum.com has a much better understanding of the loads and mass we are dealing with. [/QUOTE]
Really? Where are they getting their information from? You . . . . uh, I mean BP sure isn’t letting the rest of us in on mud weights being used, pumping rates, what pressures they are seeing at the stack etc. Keep moving your hands around real fast. . . . . . . maybe we’ll all lose sight of which walnut shell the pea is under yet.
