How to kill the BP well and perhaps why they are prolonging the disaster.
By Rick Taylor
The latest news is that the seafloor around the blow out is starting to collapse. This is bad. This is probably due to gas and oil coming around the outside of the large diameter (21 inch?) casing. Under this kind of pressure, the gas and oil can weaken the soft sediments of the sea floor around the outside of the casing. This has happen on the land many times especially in the early part of oil exploration when drillers were drilling for shallow reservoirs in loose unconsolidated rocks which are really just soft sediments. Many times the ground would collapse and the entire drilling rig would fall into a hole. In this case, the seafloor sediments are not really considered rock, but instead are soft layers of shale (really clay) and sandstone (soft sand).
I have looked at their efforts using the “containment” box. It has failed for various reasons. BP has, from the beginning, trying to salvage their well and thus their lease. Before the seafloor collapses any more and becomes a very wide, deep hole, they need to put the containment box to a different use.
They need to place the containment box over the well head and not try to gather the oil. As they get close to getting the box in place they need to be ready to pump a thousand tons of cement or what ever volume is needed to fill the containment box. Pump it down the same pipe system they are using to siphon off the oil. They do make cement that will set underwater. This would smother the well head and vent and seal off the leak. This would act as a heavy plug to stop the flow.
In the beginning they discussed using what they called a top kill method. They would run multiple pipes into the vent and pump heavy mud to stop the flow and then cement to plug the pipe. Now the flow maybe coming from outside the casing or pipe and going inside to kill the well would not do the job. A huge container box full of cement would permanently lock off their access to their well at this location which perhaps is the reason they have not tried this.
I believe they started their directional relief well in early May. It may take up to 3 months to drill this well. Sometimes it has taken much longer. They have to drill down to a certain depth and deviated from the vertical. They have to slant the hole and hit a predetermined spot about a foot wide in the current vertical hole probably thousands of feet under the sea floor bed and perhaps a half a mile away. They don’t have to go all the way to the bottom (18,000 feet). If I had to guess, they have to drill to a depth somewhere between 5,000 and 10,000’. This is a slow, tedious, highly technical task, but they can do it.
After they intersect the first well bore they should pump heavy mud into this hole followed by cement. The purpose of this is to create a permanent cement plug down hole. This is needed to take the pressure off of the containment box cement plug at the sea floor bed. This is very important to stop future leaks and kill the well permanently. By knowing the pressure in advance, this new directional relief well, would be prepared for the high pressures. They should install redundant automatic blow out preventers just in case there is a second blow out. As they are approaching the intersect area of the old well bore they should have adequate mud and cement ready to pump into the hole once they reach it.
Finally, this particular area appears to be overreaching the technical abilities of the industry. The government should not grant any more drilling permits for operations in waters this deep (5,000’).
It appears that this accident was negligence by the operator, at least on the surface. Reports from a Schlumberger crew who was on board are very disturbing. They were contracted to run a cement bond log on a long string of casing that was set after drilling to a depth of 18,000’. When they arrived on the rig, they reported that the well was still kicking (tying to blow the drilling fluid out of the hole). At this point the Schlumberger crew said the conditions were to dangerous to run a cement bond log and requested to be flown back to the mainland. The BP man in charge told them that the last helicopter was gone and would not be back for awhile and for them to get to work and rig up the logging tools. The crew then called and request that a Schlumberger helicopter come out and get them. Several hours later the rig exploded. This BP man must have been crazy.
One last note, Bush relaxed drilling regulations for these deep water wells several years ago. Obama has continued the same policy. There is a new acoustic blow out preventer device that is required equipment all over the world. It is a fail safe device. As I understand it, it permanently seals the well off, if the drilling rig cannot control the well. Every country in the world requires deep sea drillers to use this device in their territorial waters except the U. S. Why? To save a little money? No. These are multi-hundred million dollar wells. What is one more piece of safety equipment? To me, it is like the government wanted an accident to occur. From this they will surely try to get their “green economy”. And the corporations who control the government will make trillions. Despite their propaganda and what you believe, their “green economy” and their cap and trade scam will destroy the economy of the U. S.
Continued comments.
As far as BP intentions, I had to look at it from two different angles. First there is the corporate BP. The rank and file people like engineers, geos, accountants, Presidents, and CEO’s. These corporations are in the energy business. They want to find and produce hydrocarbons. This is their profession. Then you have the big, big owners; the world elite. Like Beatrix of the
And I am sure you know what her agenda is; one world government and a continuation of their economic domination. More for the haves and less for the have not’s. Their new “green economy” is just another way to continue their domination. The reason why we are still reliant on the “archaic fossil fuels” is that they wanted us reliant. And they will want us still reliant and still paying through our nose for their “green energy”.
The history of big oil is the history of creating “artificial scarcity” throughout the world. The less oil produced the more profits big oil makes. This is one of the primary reasons of going into
By the way, fossil fuels, is a myth made up by the west. Russian scientists did a massive study after World War 2. There is much evidence to believe that petroleum is what they call “abiotic”. It is not made from pre-historic dinosaurs and bugs. It is part of the earth’s primordial mass, down deep below the crust. So
I am a staunch environmentalist, but not to the point of shutting down the economies all over the world and putting the lives of people in jeopardy. There is a lot of $150 per barrel of oil in the world. The inexpensive stuff has already been found. In other words, a higher price makes more feasible to go after deeper, harder to find deposits of oil.
The environmentalists are already going after all offshore drilling. They may ban all future drilling. As for the already producing platforms, I would bet that new regulations will be added making it more difficult to produce the existing offshore fields. The new regulations and Federal control for offshore operations is just the beginning. I am sure it will later apply to onshore drilling. It is a step by step way to nationalize the industry.
The point I have been unable to get a hold of is why Obama came out months ago talking about lifting a ban on offshore drilling. Despite the lies that come out of his mouth, he is a staunch advocate of a totally “green” economy. Just like his money masters.
The money the elite would make in the carbon credit scam and the change to “green” energy towers over what BP will lose with this disaster. Remember, BP is insured. So is the drilling rig. This is another problem, reaction, solution scenario. Create an environmental problem; change the attitude of the unsuspecting public as they react by saying “ok, we have had enough of this stinking oil!” Finally provide the “green economy” solution, which is what they have always wanted.
I have nothing against solar, geothermal, wind. However the elite that control the world also controlled and suppressed the technology that might have made the age of oil, really unnecessary. I am referring to the Tesla free energy and other over unity energy devices. They have also suppressed technology of automobile engines that run off of water. Free and cheap energy for every person is not what the owners of the Earth want. Remember, as far as they are concerned it is all about them and how they can exploit and make a profit off of us. Until we tell them no, they will continue. The “green economy” is their ultimate dream. They stand to make trillions off of creating “green energy” to market to the masses. Don’t forget, green energy is very expensive. At least the “green energy they want to sell us.
Look at the billion or so that BP will ultimately lose as an investment; an investment in their “green economy” future. In their public relations, BP now stands for “Beyond Petroleum”. I wish we were beyond petroleum, even if it cost me my profession. And remember one billion is one tenth of one per cent of one trillion. Good investment.
This is an Environmental 9/11.
