Gulf of Mexico oil spill

BP's latest technical update video. Actually, some good info about what they are doing. Now paralleling things up - three containment options (short, medium and long) and two separate relief wells, one 9 days ahead of schedule. Some good graphics and ROV footage too. Worth a look. Kent Wells Technical Update - 31 May 2010
 
I heard today that they seem to be trying the top hat and pump it up method again. But apparently at first it will result in more oil spilling before starting to work.

Do they know what they are doing?
 
No worries. The video i saw of Simmons was him talking about the fact he didnt beleive so much oil could come from the end of a 21" pipe, even if it is pressured from a 50m oil reservoir. Who knows, maybe he will be proven right...

Anyhow, some food for thought....what happens when a hurricane hits oil?

Oh yeah - today is the first day of hurricane season.
 
Oh and they were going to try cutting the pipe and then capping it. Or something.

Sounds so simple I am amazed they did not try it first!
 
The risk with their current method is that cutting or moving the pipe could damage the BOP and make the whole mess worse. All previous attempts have stayed away from actually touching the leaking pipe

It's really just waiting on the relief wells. Hurricanes will mean we'll see more oil flowing freely into the ocean until they can get back out there and collect the oil again.
 
The Russians did it, several times

They successfully did it four times but not, as far as I'm aware, in the deep ocean. Even if they chose to do it in this case they still have to bore a hole deep down into the ocean seabed in which to place the bomb - it wouldn't be a case of detonating it on the ocean floor.
 
From The Oil Drum
In the meanwhile, a little calculation, based on reports that the White House has announced that the removal of the riser and drill pipe that are protruding from the Blowout Preventer (BOP) of the Deepwater Horizon well in the Gulf may increase the amount of the petroleum leak by 20% when the riser section is removed.
 
Oil hits Alabama, Mississippi barrier islands

Rust-colored oil washed ashore on barrier islands off Alabama and Mississippi on Tuesday, while more patches of crude offshore appeared to be moving toward those states' coasts, authorities reported.

Researchers scrambled to clean up tar balls and puddles of oil from the beaches of Alabama's Dauphin Island, while a strip of oil about two miles long and three feet wide stretched along Petit Bois Island, about five miles away off Mississippi, Gov. Haley Barbour's office reported.

It marked the first time oil has hit Mississippi's shores since the largest oil spill in U.S. history erupted in late April. And while tar balls associated with the Gulf spill had hit Dauphin Island, about 35 miles south of Mobile, in early May, residents said that Tuesday was the first time they had seen oil hitting the beach.

Only part of the island's beaches have been lined with protective booms, with much of those barriers lined up near a protected wildlife area on the west end of the island.

Oh dear, oh dear.

"BP PLC has concluded that its "top-kill" attempt last week to seal its broken well in the Gulf of Mexico may have failed due to a ruptured disk inside the well about 1,000 feet below the ocean floor.

The disk, part of the subsea safety infrastructure, may have ruptured during the surge of oil and gas up the well on April 20 that led to the explosion aboard the Deepwater Horizon rig,

The ruptured disk may have allowed much of the heavy drilling mud being injected into the well last week to escape into the rock formation outside of the wellbore, people familiar with BP's findings said. As a result, BP was not able to get sufficient pressure to keep the oil and gas at bay."

If the drilling mud is leaking outside the well, so is the oil and gas....although the article managed not to make the obvious conclusion.
 
Oil nears Fla. beaches as BP tries risky cap move

PORT FOURCHON, La. – The BP oil slick drifted close to the Florida Panhandle's white sand beaches for the first time as submersible robots a mile below the Gulf of Mexico made the latest risky attempt to control the seafloor gusher.

Even if it works, the current mission to cut a major pipe and cap it would only reduce the flow, not stop it. If it fails, it could make the largest oil spill in U.S. history even worse. The best hope for sealing the leak, until a permanent fix is possible in August, failed Saturday, when engineers were unable to plug it with heavy mud in a maneuver called a top kill.

Investors ran from BP's stock for a second day Wednesday, reacting to the top kill failure and the Justice Department's announcement that it was looking at criminal and civil probes into the spill, although the department did not name specific targets for prosecution.

Shares in British-based BP PLC were down 3 percent Wednesday morning in London trading after a 13 percent fall the day before. BP has lost $75 billion in market value since the spill started with an April 20 oil rig explosion and analysts expect damage claims to total billions more.

In Florida, officials confirmed an oil sheen Tuesday about nine miles from Pensacola beach, where the summer tourism season was just getting started.

Winds were forecast to blow from the south and west, pushing the slick closer to western Panhandle beaches.

Emergency crews began scouring the beaches for oil and shoring up miles of boom. County officials will use it to block oil from reaching inland waterways but plan to leave beaches unprotected because they are too difficult to protect and easier to clean up.

"It's inevitable that we will see it on the beaches," said Keith Wilkins, deputy chief of neighborhood and community services for Escambia County.

heh, a BP engineer who is an ROV controller took exception to a post by someone about their cutting abilites. 0wned.

queezyweezel: Watching the ROV work; they obviously don't have the right tools for the job, and the ROV operator is not exactly a carpenter....they're having a lot of trouble cutting the pipes. Trying to inserte the saw blade into the cut and then start the saw is never a good practice.

kendelrio : Ok, I am one of the operators of the ROVs. Let me explain to you what you are seeing. You are seeing a hydraulically controlled non-spatially correspondent 7-function rate controlled arm operating at 3,000psi. It is not coordinated like our arms. We also operate by looking at a TV screen. If you start the blade before you go in, you will be getting jagged edges and damaging more than you accomplish. You also fail to realize the pipe will not fall down and pinch the blade as a piece of wood would. (There is a crane on the surface rigged to hold it in place and lift it clear when the cut is complete.) Also, the arm is controlled by what amounts to a digital joystick (fap). It has only on/off functions in a rate controlled valve, not graduating degrees of control like you would get out of a proportionally controlled valve or servo.


As far as the tools go, that is a hydraulically operated 54" carbide tipped graphite blade designed to cut through hardened steel like the proverbial knife through butter. Guess who gets to tool up those "not the right tools for the job". Do you think we would go into a high profile situation like this just to make ourselves look like dumbasses?

Also, the pilot on the stick has over two thousand (that's 2,000 for you letter challenged types) hours of flight time. There isn't a man with less than that being allowed to even **look** at the pilot chair right now.


Understand working in water takes most of the rules you have learned on land and ass rapes them and sends them crying home to mama.

I am willing to let this go as simple ignorance, not malicious stupidity.

BTW, the article is absolutely crock.

Investigation reveals possible criminal activities connecting Obama to the spill.

http://www.examiner.com/x-37620-Con...nal-activity-connecting-Obama-to-BP-oil-spill

The new line of defense employed by the Obama Administration to deflect criticism of its lackadaisical handling of the BP oil spill is to launch a criminal investigation of the company.

Perhaps this is the best thing that could happen. Such an investigation would, of course, uncover all of BP's connections to the Democratic Party and Barack Obama, who were the single largest beneficiaries of BP campaign contributions over the last 10 years.

(AP Photo/Susan Walsh).

Granted, the Obama Justice Department, under the leadership of Obama lackey Eric Holder, would never delve into any real criminal activity if it involved revelations concerning the Administration's connections to BP, as well as the cozy relationship the company has with Democrats on the Hill.

Someone else, however, has already done such an investigation and has uncovered explosive information that possibly implicates Barack Obama, certain members of his Administration, and Democrats in Congress, in the committing of crimes.

The key is to follow the money trail.

JoAnne Moretti, along with a team of investigators, delved into records which pointed to a paper trail connecting the major players in this disaster--BP, Deep Water Horizon, Halliburton, Citigroup, Goldman-Sachs, the U.S. Government, and a company called 'NALCO.'

A few recognizable names of individuals involved in the paper trail also surfaced--Warren Buffet, George Soros, John Holdren, Tony Rezko....and Barack Obama.

At the heart of the scandal which Moretti reveals is the concerted effort by all of these major players to delay the cutting off of the oil flow into the Gulf of Mexico.

Why?

The bottom line--NALCO is the manufacturer of chemical dispersements and water purification systems that are being used in the Gulf to attempt to 'disperse the oil before it reaches the shoreline.'

This is what is known as 'the top kill' method which BP has claimed is the best manner possible of dealing with the spill. The top kill method, however, does nothing to actually stop the flow of oil from its source--the well hidden deep in the waters of the Gulf of Mexico.

The Obama Administration and BP have been noticeably lazy about stopping the flow of oil into the waters of the Gulf. Obama claimed that as soon as the explosion of the oil rig occurred, Federal SWOT teams were dispatched to the area in order to 'secure it.' The notion that the Obama Administration did not know the extent of the leak is contradicted by the announcement that federal teams were 'on the scene from day one.'

Obama claims that he backed off from doing anything to stop the oil leak in deference to BP, which he claims was better equipped to deal with the situation. And indeed, that much is true. BP did, in fact, say such a thing publicly.

But BP's interest in actually cutting off the flow of oil into the Gulf is just as suspect as the U.S. Government's.

And here is where the story takes a sordid, and potentially criminal, turn.

Clicky link for more. Tenner says this never makes the BBC. :D
 
A guy on another forum, said he lives near Biloxi, he said you can smell it in the air, and he's been getting nosebleeds, 3 in a week, which is apparently rare for him. He said it's all over the shoreline :(
 
This is the nightmare scenario. Well control relies critically on ensuring that the only possible path to surface is inside the green path in barking's schematic. One possibility is that there is an exit point somewhere and oil and gas is leaking "behind" the green tubing (through the annulus formed with the casing) to surface. If any of the seals between the different casings are passing, the only thing containing *that* path is bare rock and an even worse possibility is that somewhere on that path it is entering a natural fracture in the earth, and being transported to the surface, possibly miles away to some currently unknown leak point.

You can find youtube videos of gas blowouts, and often see that the locus of the bubbles is some way from the rig - this is fracture transport. Although *very* unlikely, this would account for the difference in volumes observed and volumes estimated from the known leak points. You could tell if they had encountered fractures during drilling from the drilling record, which of course BP is not publishing.

If casing integrity has been lost, the intercept wells have to intercept *below* that point or their integrity is also bypassed - the deeper the leak point, the harder that is. At the limit, where the leak point is right at the entry point to the reservoir, the leak is irreparable.

This natural fracture theory, which Prof Simmons also mentioned, is all making a lot of sense. This would explain these city sized plumes developing several miles from the broken well head leak sites, which several scientific reports have described as gushing straight out of the sea bed (i.e. not from a broken well head) like a "volcano". B.P. claim these plumes don't exist and haven't as far as I can recall made any comment yet about these leak sites. Once they drill the relief wells this would presumably reduce the pressure and reduce the flow from them. If there is such a natural fracture, can they not just dump tons of rubble and cement onto the sea floor to plug it?

As I understand it BP (or Tony Hayward) has said that no underwater plumes exist (period), i dont think they were specifically referring to any that had developed by a natural fault in the seabed and were the result of the main oil well having broken.

VENICE, La. — Disputing scientists' claims of large oil plumes suspended underwater in the Gulf of Mexico, BP PLC's chief executive on Sunday said the company has largely narrowed the focus of its cleanup to surface slicks rolling into Louisiana's coastal marshes.

During a tour of a BP PLC staging area for cleanup workers, CEO Tony Hayward said the company's sampling showed "no evidence" that oil was suspended in large masses beneath the surface. He didn't elaborate on how the testing was done.

Hayward said that oil's natural tendency is to rise to the surface, and any oil found underwater was in the process of working its way up.

"The oil is on the surface," Hayward said. "There aren't any plumes."

The idea that there are substantial leaks from the main oil well (ie leaking through the casing) were given some credibility from a WSJ report:

....The disk, part of the subsea safety infrastructure, may have ruptured during the surge of oil and gas up the well on April 20 that led to the explosion aboard the Deepwater Horizon rig, BP officials said. The rig sank two days later, triggering a leak that has since become the worst in U.S. history.

The broken disk may have prevented the heavy drilling mud injected into the well last week from getting far enough down the well to overcome the pressure from the escaping oil and gas, people familiar with BP's findings said. They said much of the drilling mud may also have escaped from the well into the rock formation outside the wellbore.

As a result, BP wasn't able to get sufficient pressure to keep the oil and gas at bay. If they had been able to build up sufficient pressure, the company had hoped to pump in cement and seal off the well. The effort was deemed a failure on Saturday.

BP started the top-kill effort Wednesday afternoon, shooting heavy drilling fluids into the broken valve known as a blowout preventer. The mud was driven by a 30,000 horsepower pump installed on a ship at the surface. But it was clear from the start that a lot of the "kill mud" was leaking out instead of going down into the well.

Oil Drum forum folk said that there was no disk at the point the article claimed and said they were either wrong or they were not getting their terminology correct (which wouldnt be unusual given they are journos and not oil industry experts). I did e-amil the two journos and asked for clarification but so far no reply....
 
Fitch have downgraded BP's credit rating to AA. This increases their cost of capital - they now have to pay a higher interest rate on their debt to compensate the lender for the higher risk of non-payment. That in turn increases the production cost of their oil.

This probably is more a reflection of general doubts about the oil industry's ability to manage the risks of deepwater drilling, rather than specific doubt about BP. So it marks an increase in the capital cost of all deepwater drilling. That's serious, because this is the only source of production increases since 2005, so it is a structural increase in the price of oil. The global economy crashes at oil prices >$80 real, commercial airlines go bust, etc.

Another consequence of this event is that it shows that the technical complexity of marginal ("unconventional") oil is now such that failure risks exceed the capacity of any single energy company or insurance company to cover. So I think at best there will have to be more consolidation (Exxon buys BP, for example) just to beef up liability cover. Either that or a formal legal arrangement with the host government to underwrite and socialise the risk. Which is a bit hard, since the US is insolvent.

If and when they lift the moratorium on deepwater drilling, 4.6% per annum depletion in the conventional base will have knocked out 1-2 million barrels a day of installed production capacity. I think we'll find that 2008 was the peak of global oil production, not the EIA's 2011 forecast.

(And BP has been advised to withhold dividends until the liability can be worked out - that's a truck load of UK pension funding. This post really ought to have been made to the global financial implosion thread.)

There is another study that suggests you could get just about 100,000 barrels/day out of the known leak points, and the fracture thing is nightmarish and pretty unlikely, so it is very hard to say. BP are just too compromised in their interests to be relied on for any kind of determination - this needs to be a third party assessment. You couldn't drop rubble on it - it would be like stuffing sand up a bath tap to try and block it.
 
Well at least there is some progress, they seem to have cut the pipe even though they left a jagged edge which may mean they cannot seal well against it.

Hope the next step goes a bit better.
