the slick. clouds obscure most of plaq parish
it's not very clear at all though and I think the red line is underestimating the extent of the sheen.

yes.

The choke, kil etc are smaller pipe of some sort I understand. how does the drill stem/pipe (the APT threaded stuff ive seen...about 4" od and very heavy wall) progress through the riser with all the other lines in the riser?
they are on the outside of the riser running parellel to the main tube.

What space does the mud return to the rig through?
throught the main tube of the riser.

What goes through the BOP? ie
drill pipe and casing

they may have been nearby the rig, but if they were tied to a floater, their boat would be beaten to shite.

I just found the story of some fisherman who were tied to the rig when things began to go wrong, and witnessed the explosions. It is an amazing story.
That story is total bullshite. They would not have been allowed to tie up to the Horizon.
They could have been in the area. The thread that you linked provides a link to another site that is down so I can't read the whole story.
Cadello,
Please don't post crap like that.

Someone posted a picture of the riser pipe. Much more complex joint than I was thinking. I understand it much better. I like asking questions when I get good answers, if you get tired just tell me youve had enough...I am used to it.
So the choke, kill, etc stop at the bop?
Am I correct in that they provide control to some functions of the bop?
Does the bop provide more function than just the shearing of the casing and the drill stem?
Also, it sounds like you are able to control the passage of fluids etc through the annulus (ie opening and closing the annular???) is this correct?

Back to the original topic "Oil Spill and Offshore Fishing" here is a link to the map showing the areas off limits to recreational and commercial fisherman.

I've been in the books for a while recently and I missed a lot of the now updates.
Any word on the sheen moving W towards our area and closing that down too?

Not that map makes since. What the news was showing was the coastline plus inland a little. That did not make since. The waters closed, Is that federal waters? I'm not a big offshore fisherman so I am not quite sure where fed waters start. Can Feds close inland state waters? Thought that would be state decision. Who would want to go in that area anyhow? That area closed to fishing should be a no brainer. I would hate to foul up my 100K + boat in that mess, unless I was helping protect the coast from the oil.

kinda. you see, there is also a control line that goes down with the riser jts that provides electronic/hydraulic power to the stack.

of course. there are pipe rams that will close around the pipe without shearing it. there are two annulars that will do the same thing. there are failsafe valves that will open the choke and kill lines letting you bring back fluid to the rig through them while the annular is closed. there are failsafes that open so that you can pump down the choke and kill lines and bring back stuff through the riser. you see, there is a choke manifold on the rig floor that can be lined up in many different ways to pump down the hole.
when the well is taking a kick, you first close off the annulars, open those failsafe valves, and monitor what comes back through the choke and kill lines. these lines essentially "feed" the choke manifold. from this manifold, you can feed the kick to many different sections of the rig. basically.
so, when you hear the term "they were on the choke", that means that the annular bags where closed around the pipe and the failsafe valves were open to monitor the well's flow.

federal waters begin 3 miles from the coast line in LA MS AL and FL(I think) and 10 miles from TX.

Looks like it is just Federal waters closed from the mouth of the river east. I think it would be up to the state to close inshore and that may be a real possibility once the oil hit the marsh. If there is any good news to this it looks like everything is staying east of the mouth of the river. Unless someone has any evidence other wise I haven't seen anything moving west of the river.

Can someone explain to me how this spill is NOT worse than the Exxon Valdez? This is an open, gushing well of oil unlike the Valdez which was a ton of oil - but a fixed amount from within the ship.
What am I missing here?

North winds sure will help. My friend here in town is scared to loose business over this. Fishing tackle does not sell well when fishing is closed or if oil makes a heavy land fall.

Everyone is comparing total spilled by EV with currently spilled from Deepwater Horizon.
So, as of now, total barrels of oil spilled by the rig is less than total barrels of oil spilled by Valdez.
I've heard that the rate of the spill could potentially jump to to the area of 40,000 or 50,000 barrels per day if the riser were to go out.
Has anyone else heard this, or can shed some light? (mylsuhat or tigerdup07)

your friend will be compensated.

I would really be surprised if that were the case. I think 20,000 barrels is probably a reasonable worse case flow from this well but I am curious to hear what others think.

that makes NO SENSE at all. the riser has ZERO to do with the flow of oil.
Posted on 5/3/10 at 8:58 am to tigerdup07
Yeah i dont know where they were going with the riser going out issue either. I guess they were implying if the flow of oil was completely unrestricted then it might get that high. But honestly what is restricting the flow right now anyway?
