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."

Then, utilizing the remaining wellhead (and possibly Christmas tree) structure (which, fortunately, weren't all vaporized by cowboys who think "if some explosives are good, more are better"), crews cap the well using mechanical means (such as installing a new valve).

    It seems to me that the last thing that one would want to do in this case is blow up the BOP - it's routing, and apparently choking off much of, the flow. If a failed explosive attempt were to destroy/disconnect the BOP yet not seal the well I think we would be looking back at the current flow nostalgically. Given the apparent lack of experience using explosives to deal with a situation like this it seems likely too risky to attempt -- given that the relief wells are eventually expected to solve the problem.

    "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.
