and it may be. I just tend to believe what my sources say over some scientist who isn't privy to all the data that my sources have.

Sounds like the recruiting board

My guess would be the temperature of the fluids is so high compared to the surrounding water its just rising straight up.

Appreciate the reply, but that's a big heat sink and you would think it would cool things rapidly.

That it could take a while and/or several tries.


But things are definitely moving in the correct direction right?

Everything is essentially going according to plan from what I understand but people need to be patient. It's like any construction project where you're dealing with soil (or mud in this case) it actually has to settle out before you can move onto the next step correct?

As long as this process is "working" I'm tickled and cautiously optimistic.

Thanks you guys who have connections for keeping everyone abreast of developments.

Those were night shift guys and haven't talked to them since. The day shift guys were upbeat on the progress. At some point today a formal press release will come out from BP.

They are really tight lipped about about information coming out of the central command center.

Question to anyone who knows. The mud is dense, that is heavier than water. I also know that the ROV seems quite close. However, given the amount of time the mud has been spewing you would think the area would be quite murky, but that picture seems quite clear. Does anyone know why?

we have situations like this when you're drilling the top hole section of a well -- the first section of the well, drilled without BOP's using waterbased mud. the mud is circulated up to the mudline and runs out on the seafloor, and the ROV sits down there monitoring the situation for however long it takes us to drill the necessary footage (ususally ~1500-2500').

anyway, the mud is still dense as it runs out, so it falls down to the mudline after existing the top of the 36" casing. it doesn't atomize or anything.

what really messes up visibility is when the bottom is disturbed an all those little mud / sand particles get up in your field of vision. it takes forever for them to fall back to bottom, and since there's very little current (or usually none) on bottom everything just sort of hands there.

This is my laymans read of the situation and not based on anything from my contact. It appears to currently be status quo for lack of a better term. No positive or negative movement. Perhaps some of our other industry folks on the board may have a better reading.

And TigerFred, thanks for the update.

Maybe the ROV camera is too close to tell what that mud is like, but to my ignorant eyes it seemed like the mud was being atomized as it was spraying up. It was just an observation that didn't look visually right. Probably just an optical allusion. Thanks for replying.

That is a very good point.

So are you suggesting that the billions of gallons of the bottom ocean layer at 36 degrees might soak up a little heat?

I am laughing at myself. Of course, you are right. Plus, when they pulled it out, it looked like it was just a wrench.

Do you think they are trying to get a read on the opaqueness in order to tell if it is oil or mud? I am scratching my head looking for reasons why you would stick a wrench into that flow.

you have to remember that "mud" is not just dirty water. it's a dense, viscous solution that's designed to hold together during drilling and carry debris out of the well and back to surface. it consists of the base fluid (water), barite, gels, polymers, and other additives to give it strength.

Good grief how far we've come. When my grandpa was a kid..........mud was mud.

So approx how much does mud cost per gal/barrel? and how much do you think they will use to finish the job?....just curious....

No idea how much it costs. But I read in the T-P that there is 50,000 bbls on board the ship. I'm sure they can get more if they need it but the sentiment seems to be that if they need more than that, it's not working.

It ain't cheap, and they will use a couple of boatloads.

You ever notice how production is measured in barrels, but spills are measured in gallons?

I have no idea. I looked at the video because posters were discussing the wrench and didn't see what they did.

I am going to nominate oilfieldtiger, TigerFred, and COTiger to moderate this board.

This is old data, but a couple of years ago it was about $30,000 per day for a rig that was simply tripping with small losses. They are losing most of the mud they pump here, so the cost is going to be many, many times that.

It was a wrench. No doubt about it.
