I Hope not But…BP’s Top Kill Could Lead to a Disaster

Golfballs on the Sea Floor

People, I hate  pouring cold water on somebody’s frenzied efforts , specially  if those efforts  are aimed at stopping the Gulf of Mexico blowout oil spill which is turning out to be our worst nightmare, but really you have to examine closely what BP is attempting to do.

What exactly is topkill?  It’s supposed to be a proven method used for land-based oil wells in Kuwait that needed to be shut down. It’s applying counter-pressure on the blowout top of the oil pipe using injected hydraulic fluids, (synthetic?) mud, shards(of what?) later cement, and oh yes, according to BP also golf balls. I mean why not ? We can even use the kitchen sink, for all I care, if it’s going to get the job done. Let’s just remember that this method is being attempted about 500 miles  down to the ocean floor.

And what exactly is my apprehension?  The oil that gushes out from a land-based oil well is coming from  a shallower  source in the earth’s crust compared  to the undersea oil  leak where the pressure nearer to the earth’s core is greater.  So if the method proved successful in Kuwaiti oil fields,  couldn’t we just say it would do the same for our undersea oil spill?  “’Tain’t necessarily so”, as the song goes. Let’s remember that much of BP’s own investigation of the Deepwater Horizon oil rig blowup pointed to a leak of gases into the cement that was poured into one of the oil pipes, rendering the cement prone to fracture, and thus the blowout from the weak spot. Spelled technically,  the first crisis of having a state of the art oil rig explode from underwater  due to the pressure encountered which surpassed  the usual means of sealing an oil pipe (filling pipe with cement) should already tell us that we are dealing  with a whole lot more of pressure than is usually encountered. To be able to cap this successfully, we have to be sure of two things; (1) There must be no other weak spots along the oil pipeline which can give another blowout rupture when counter pressure (topkill) is applied (2) The amount of counter-pressure to be applied should be significantly be more (like 3-5X more) than the pressure coming out.  This 2nd “must” can be predicted through repeated pressure readings before the topkill.  If there are uncertainties about those two, better not attempt topkill. Try going through (I mean sincerely going through) those submitted ideas being collected by the Deepwater Horizon website which aim to contain and redirect this oil spill away from eco-sensitive areas rather than counter-pressuring a man-made tap into mother nature’s fury.  So remember, folks – we’re still dealing with mother earth’s most combustible material – oil. Just think what a nuke would do to that, aside from punching a bigger hole in the earth’s crust and releasing  more oil spillouts enough to kill the remaining marine life, not to mention coastal economic life.  So limit your thoughts of  nukes  to Predators for the Bin Ladenists.

 

To be fair, BP’s first containment dome idea could have worked. The only flaw in the design was an outflow pipe on top which was too narrow with respect to the size of the dome. As this containment dome was applied over the leak, it narrowed the confines of  a gushing undersea high-pressure oil pipe leak, together with the surrounding seabed floor causing increased turbulence  of an oil and seabed debris mixture which was enough to clog the outlet as it worked its way out of the dome. This seems more plausible than what was being advertised as “ice crystals” which “precipitated “ to clog the outlet. Once this design flaw is addressed (enlarging the outflow pipe on the dome top)and applied, we would be closer to solving the worst marine disaster on the Gulf of Mexico. Better that rather than seeing the continued undersea oil  pollution with golf balls on the seabed floor to boot.

I understand your point, but, while not being very knowledgeable of how rigs and pipelines work, I don't think it would be the same. The pipeline broke or exploded above the seabed where the pipe was weakest, plugging this pipe where it meets the seabed would probably be better since the seabed will provide more structural integrity to the pipe underground so the pressure may not break the pipe so easily, although it may simply "pop the cork" on the fluids and cement (and golfballs?) they plan to use to seal the leak. Like I said I am simply assuming and not posting a fact.

They aren't plugging the pipe above the seabed. The drill pipe didn't explode above the BOP. The damaged pipe happened when the rig sank.

The top kill procedure is simply to reduce the pressure so that a proper cementing job can be done so the well can be shut-in. The golf ball an rubber tire pieces are a separate procedure called a junk shot. The goal is the same.

I see so many people up in arms about BP/Transocean/Halliburton but why is no one asking the question that matters most. Where was the MMS along the way. They can't seem to provide a report from the last time that rig was due to be inspected just several days before the blowout. They can't produce reports for half of the possible 108 rig inspections that should have been performed on the Horizon. These guys were too busy doing meth, looking at porn and taking free hunting trips to get out there and do their job.

We pay taxes so these bozos go out there and make sure that popper safety procedures are followed. You can say that corners were cut by the companies involved but if our regulators weren't taking bribes to look the other way, our government is just as much to blame. This administration is sitting on its hands. They are busy quadrupling the tax on a barrel of oil and suspending drilling permits and leases. They aren't on the ground protecting the fragile ecosystem that is the Louisiana marshlands.

BP, Transocean and Halliburton should have made better decisions with the warning signs given to them. They should have spent extra money on the BOP stack to provide additional fail safes. But, we all know that corporate America doesn't do anything they aren't forced to and that doesn't just include the oil and gas industry.

Thanks Just John.  I was hoping you would chime in with your expertise.

I'm in no way an expert. I just work around this stuff for one of the top 25 safest companies in Louisiana. I can say from direct experience that even when you do it all right, blowouts happen. I really feel like the companies involved ignored a few good warning signs while trying to just get it finished.

Most people are unaware of how rigs and drilling work. The company I work for drills wells. Consider us BP in this scenario except we work as contract operators. We are not the owner of the well. We lease a rig from a company (Transocean in this situation). They are responsible for providing the crew and workforce associated with the operation. We provide "the company man". Everybody there works for him without being employed by him. He is the final word on the rig. When specialized operations are required (i.e. cementing or fracturing) another company is called in to perform that work (Halliburton). The company man is still in charge of those crews but they do not work for him.

All along the way, proper communication of what is going on is required. The company man probably answers to a group of engineers who use science to overcome drilling obstacles. They answer questions about what's going on by looking at logs and wellbore schematics. It's not just attaching a drill bit to the end of a section of pipe and spinning it. They are constantly pumping drilling mud into the pipe to carry debris back to the surface around the outside of the drill pipe. Once total depth is reached, they stop the mud and pump in cement. This locks the casing in place and in most cases the well is shut in for later completion.

In the case of these offshore operations, they are often flowing a well at the same time they are drilling it. Oil and gas is constantly coming to the surface and there is always some amount of back pressure on the drill string. It is the spikes in pressure that are important.

We can be mad at the company man and the rig owners and the service crews. They are ultimately responsible for this situation. The fingers are going to continue to fly in an accusatory manner even after somebody comes back and says this is definitively what happened.

We should be livid that the government officials that we pay to oversee these operations were seriously not doing their jobs. Corporations never do the right thing. Sometimes they send guys on paid hunting trips or don't complain when they know that an inspection was missed over and over.

Personally, I don't really think that BP has done enough to protect our wetlands and fisheries. They have probably made it worse with some of the things they have tried. But, if you look at who is doing something and who is watching it all unfold from the security of his oval office, BP looks like a shining star in the wake of a horrific accident.

I appreciate your admission of not being an expert, but I did say expertise, and you have provided a great and easy to understand explanation of how things work, and what is going on (you are closer to it than most of us).

I think you are right in your political summation, but neglect one thing.  The fawning press.  That is why Obama will skate on this, when clearly he was the chicken with no head running around.  Even his press conference reminded me not of a president, but of a pretender - Alexander Haig circa 1981.  He stayed as far away as he could until he was sure he could come out and claim he was in control.  Many will see that as an act of cowardice, not of a commander. Sadly, the press will never report it that way,  Their ears are too full of Obamapoop due to the location of their heads.

Well... at least the press has finally removed their heads from their own buts. To bad they shoved their noses to far up another.

Yea, it is not "napalm in the morning" they are smelling. ;)

BTW - looks like the top kill is working. They have it to low pressure and are going for zero pressure and cement. It also look like they did put in some 'junk'.
