BP's Final "Top Kill" Procedure For Gulf Oil Spill

eldavojohn writes "So far every attempted fix has resulted in failure to contain the Gulf of Mexico oil spill with the exception of the riser insertion method that appears to be little more than a mile-long tube sucking up oil. After attempting many options to allow the continued collection of crude oil, BP is finally considering a 'top kill' option that will kill the well. A vessel at the surface will use 30,000 horsepower pumps to slam kill mud and clay into the well's bent riser, allowing them to cap the well off with two relief wells (which won't be ready for several months). If that fails, the vessel will move on to a 'junk shot' that involves spewing larger debris like shredded rubber and golf balls into the lines to gum up the flow and stop it. Government officials acknowledge that while this may provide a solution, it may also worsen the situation if the resulting pressure causes the lines to blow or fail at other points. While this is likely one of the worst environmental disasters to hit the gulf, BP's debacle has caused Shell to pre-build cofferdams into seven wells that it is currently drilling in the gulf. These would drop into place in the event of such a catastrophic failure of a riser under the well."

    There are access pipes on the BOP itself for this kind of stuff.

    The mud or junk will therefore be inserted BEFORE the riser pipe.

    Blocking the riser would be useless given it's bent, cracked at the BOP and could potentially rip off due to the blockage.

    I was watching a documentary on this Sunday. They interviewed one of the rig survivors. According to the survivor, pieces of the blowout prevention device had come up the pipe weeks before. They didn't bother to fix the BOP. When one of the controllers on the BOP failed, again, weeks before the accident, they didn't bother to fix the BOP. When Transocean wanted to put 3 cement plugs in the well, sandwiching the heavy drilling fluid, the BP managers said "No, use 2 plugs," so that it would take BP less time to unseal the well when they hooked up the pumping rig. According to the survivor, it was when they took the pressure off the well, with only two plugs, that the plugs failed.

    This is people putting money before safety. This isn't an "accident". I would consider an earthquake ripping the BOP off the well an accident. I would consider a jet crashing on the rig and somehow managing to destroy the BOP an accident. This was people cutting corners and getting caught.

    BP hired a top oilfield service company to test the strength of cement linings on the Deepwater Horizon's well, but sent the firm's workers home 11 hours before the rig exploded April 20 without performing a final check that a top cementing company executive called "the only test that can really determine the actual effectiveness" of the well's seal.

    A spokesman for the testing firm, Schlumberger, said BP had a Schlumberger team and equipment for sending acoustic testing lines down the well "on standby" from April 18 to April 20. But BP never asked the Schlumberger crew to perform the acoustic test and sent its members back to Louisiana on a regularly scheduled helicopter flight at 11 a.m., Schlumberger spokesman Stephen T. Harris said.

    At a few minutes before 10 p.m., a belch of natural gas shot out of the well, up a riser pipe to the rig above, igniting massive explosions, killing 11 crewmembers and sending millions of gallons of crude oil into the Gulf. The rig's owner, Transocean, blames failed cement seals, installed by Halliburton, for the disastrous blowout.

  15. Not a simple problem by cdrguru · · Score: 5, Interesting

    With the pressures and temperatures involved this is actually a very difficult problem to solve.

    You can't just put a cork in the damaged pipes - the pressures are on the scale of being unbelivable. I believe it is around 150,000 PSI. Virtually nothing is going to withstand that sort of pressure without a lot of help.

    Similarly, I keep seeing posts about how TransOcean should have "fixed" the blowout preventer when it was apparent that some seals were breaking down. Or when one of the redundant controllers failed. The problem is, it was a mile underwater. I do not believe anyone in the area had a means of working at that depth. Also, you can't just turn a valve under the blowout preventer - it is pretty much the bottom valve. So replacing this isn't an option - you are pretty much stuck with it unless you are prepared to do something drastic.

    On land, you could (possibly) remove everything from the well head and accept the massive leak that would occur. I do not believe there are many land-based wells where the outflow pressure is anywhere near 150,000 PSI. So changing the blowout preventor is nasty, going to spew oil everywhere but is at least possible. At 5000+ feet of water and with the entire Gulf squeezing the oil out through that pipe changing the blowout preventer is simply not possible.

    You folks do understand that the weight of the water above the well is what is causing this problem, right?

    Another silly point people seem to be hung up on is that BP is working on this and the government isn't. Well, the government as a regulator has some involvement but about all they can do is make rules. There is no government oil well rescue service. The facilities do not exist within the US government, and probably for good reason - it doesn't happen all that much. The US could, I suppose, nationalize BP because of this. The problem with that idea is that a lot of other companies, oil and otherwise, would take this as an immediate indication that any US presence was no longer safe. The same thing happened in a lot of Central and South American countries upon nationalizing companies. The reason a lot of companies are in the US is because it is convenient to be close to a large market and a well educated labor force. Make noises like assets aren't safe from being nationalized and a lot of companies will take their assets elsewhere.

    You folks also understand that this well is in international waters, right? The US can drill there or any other country. The US has attempted to claim 200 mile nautical boundaries before, but that is pretty much a joke today. The fact that the oil is there means it will be taken out by someone. We get to choose whether it is the US or someone else. I'd say Venezuela or Mexico are likely candidates if we abandon drilling in the Gulf. At this point I would say complete abandonment of US offshore drilling is likely, regardless of the economic consequences.

  16. The myth that they want to "collect the oil" by Anonymous Coward · · Score: 5, Insightful

    "After attempting many options to allow the continued collection of crude oil, BP is finally considering a 'top kill' option that will kill the well."

    Why are people coming up with this fantasy that BP wants to keep the hole viable, and wants to continue collecting or be able in the future to collect oil from this hole? Some people have developed the misconception that the only reason BP hasn't tried to plug the hole is that they want the oil to flow -- i.e. $$$$$$. It's total nonsense. Why?

    A) the hole at depth and the equipment on top of it is damaged. It would be foolhardy and inconsistent with industry practice in a situation like this -- especially if instability in the hole due to melting hydrates is an issue at depth in the well -- to try to keep the hole operational. The plan was, and always will be, to stop the flow from the hole and then cement and abandon this hole once it is stopped. To produce this field they will have to drill new holes. That was and always will be the case, and BP said that was the case from the start;

    B) they deployed various collection devices earlier because they are faster to deploy and do not depend on being certain about the state of the deeper borehole or the blowout preventer (BOP), both of which had to be thoroughly assessed before attempting techniques that would plug the well, especially when it was known that the BOP failed to perform the way it was supposed to and the hole was unstable. You don't fiddle with things like this when they are in an "unknown state". If they proceeded to try a "top kill" without that assessment they would run the risk of making things worse if a subsurface blowout occurred when pressures built up (i.e. the pipe failed below the sea bottom) or something failed in the BOP;

    C) the oil coming out (even with upward-revised numbers) is a piddling amount compared to normal oil production rates in these types of wells when they are working properly, and the value of the oil is dwarfed by the costs of collecting it like this. Even if it were flowing at 10000 barrels a day and they collected it all, that's a "mere" $700000/day (10000 * ~$70 USD/barrel), which wouldn't cover half the daily costs of all the vessels and other gear they have on-site trying to fix the problem ($500k/day is routine for ONE rig when you add in all the materials, personnel, and support. Here are costs for just the rig contract alone -- the Semisub 4000'+ WD is the relevant one at $411k/day). Usually a rig or subsea production system in this setting will be producing from multiple holes simultaneously -- that's the only way it is economic. It would be economically stupid to try to produce from the well in its current state and with the setup they have on site. Get a clue, people!

    Anyone who thinks the delay in resorting to a "top kill" solution is due to some kind of ulterior financial motive on the part of BP doesn't understand the technical challenges of doing any of this stuff at extreme depths or what the real economic situation is. They're resorting to a "top kill" now because they've finished the X-ray and gamma-ray studies of the damaged BOP that give them confidence the whole thing isn't going to blow up in their face when they try to plug it. The other techniques were worth trying in the interim. That's the whole explanation for what they've done. It's nothing nefarious.

    Hold BP and other oil companies responsible for accidents. Remember that they are drilling at the ends of the Earth to satisfy *your* demand for this resource, so perhaps try to cut back a bit. Beef up safety regulations and inspections. Diligently work on alternative energy sources. But for god's green Earth's sake, leave the stupid conspiracy theories out of it. This "they haven't plugged it because they want the oil to flow so they can make money" one doesn't make a speck of technical or economic sense.

However, I believe there is a fundamental difference between the two events: what exactly is the administration supposed to do? The fix for this was going to take weeks. Everyone reasonable knows it. New wells have to be drilled to relieve the pressure. That is the ONLY way to safely shut this thing down. Everything else that has been happening is theatre. Experts knew from the moment that this happened that we were going to have oil pumping into the Gulf for six weeks, and that the entire Gulf had just been handed a death sentence. No amount of "taking charge" was going to change that.

    Obama hasn't "taken charge" because he knows that BP is going to catch the blame when none of these other "fixes" work. That's smart. Contrast this with the actual Katrina: there were known things that could have been done to relieve the disaster situation in New Orleans, that were actually the responsibility of the Federal government to do, that did not get done. Bush actually failed to act when there was work to be done, whereas there is not much here for Obama to do.
