Louisiana and BP: Methane hydrate is acting up

[Econosaurus]

Good evening
it has been going on for almost two months and I ask myself the question;
why does the United States with the colossal means at its disposal do nothing technically and let BP, which is apparently incompetent, do its thing?

Well, apparently it was BP who bought the most sophisticated devices... So after that, here's what...
It's complicated, and we don't know everything, because plugging the leak, if they want, they may be able to, but we mustn't forget the financial issues we talked about previously, which have an enormous weight in decisions.

Then there's the nuclear bomb... A warhead threaded through one of the two holes they're drilling as an emergency well, then we cement the hole, and once it's dry ==> BIM! So as to crush the leaking well by the pressure of the detonation.

...there was much better to achieve with injection cement!

What we do among other things to "anchor" retaining walls.

1) Drill three holes deep enough around the wellhead, to install anchor cables.
2) Flooding of the tie rods by injection of quick cement for soil consolidation in the form of three pockets at the bottom of the three boreholes.
3) Once the cement has dried, the tie rods are trapped in pockets of cement at the end of the borehole.

As a result, it would have given enough support to resist the pressure, and with a collar they could have encased the tube of the pipe in it. No need to fix it with nuts, once in place it was enough to make a weld all around... The flow of the crude cooling de facto the walls of the pipe, there was no danger.
And so on...

We are only waiting for the aces of econology to solve the problem and save our beaches in 2011 and save the planet!!

But US justice has banned the moratorium on offshore drilling!!
It will prohibit the aces of econology as well from swinging BP!!!

Problem to anchor you need very hard solid and the sedimentary bottom full of methane hydrate is all soft probably almost like methane!!!!
Without a fulcrum, we cannot lift the world!!

BP and the USA are in trouble!!!

The next seasons will be hot….

(Like floating wood, oil will cross the Atlantic, without the help of supertankers...)

Impressive the gas field that has been burning for 40 years.

Ah, I didn't know...But filming the deck of the ship...wow if the law says so...

I saw that, I also saw when they put the robot back in the sea (I described it above) Not only do they have an obligation to film 24 hours a day, but they must imperatively broadcast the images on the web!

Drilling method
First, they already have a map of the bottom and the area, with cores that have already been taken. They did it beforehand, even before the drilling, if only to make sure that the place where they were going to drill was going to hold up. So they know very well where they are at the local level. If not then it is to despair. But frankly I do not believe that a geologist would have given the green light in a dangerous zone (I saw the thesis of methane, I will come back to it later).

The deposit formation thesis (oil) through plate tectonics
It is the result of the imprisonment of organic matter by the play of the sliding of said plates.

In the Gulf of Mexico: 1) The formation of gas pockets. 2) multiple deposits. 3) in several places 4) and at several depths 5) the strong pressure... are as many elements which would prove that these conditions were met. There is also a section of the layers, higher in this thread, which attests to this.

Seabed and plate tectonics
Tell me if I'm wrong but silicates (composed of sand) are the main constituents of the earth's mantle and crust (~30%).
I wouldn't confuse the "sedimentary layers" and other shelly limestone, with variegated sandstone. Sandstone is already a natural cement composed of different silica derivatives.
Apart from the silica and the saline deposit, everything therefore rests on the Triassic composed of strata of sandstone/variegated sandstone, limestone (shell) and an upper layer of detrital deposits. The whole forming the oceanic crust.

In addition, we saw dumpsters placed on the bottom, not far from the borehole and they did not seem to have sunk into soft ground! And no presence of gas fumaroles.

On area
So it would have been wise to proceed as recommended, since it is completely local and the anchoring in the sandstone should be perfect. And even without that (one can always doubt) the constitution of pockets of cement injected at a certain depth in the ground, at the very bottom of the openings intended to receive the anchoring rods, should be sufficient on their own, even what by their own weight increased by the pressure of the water above => it's just a basic calculation to do, right?! Moreover, the simple fact of drilling would give them the composition and resistance of the ground!!!

This is why the methane thesis, I hardly believe in it, is rather to drown the fish and save them time to dig their parallel well(s) because any additional operation "of rescue" wastes them time, hydrocarbons, and therefore dollars.

It's not just in the sea that oil pollutes...

In Los Angeles, the nightmare of the inhabitants of a city contaminated by Shell, Le Monde, 21/06/10, 15:24 p.m.
Claudine Mulard, Los Angeles correspondence

With its 285 pavilions aligned, its palm trees and its green lawns, the city of Carousel in Carson, a locality south of Los Angeles, has everything of the American dream. That's what Royalene Fernandez and her husband thought when they moved there in 1968 with their young children, unaware that the land had belonged to Shell. She has suffered from leukemia for eighteen years, a disease that may be linked to benzene toxicity. However, recent tests carried out by the Regional Water Quality Control agency revealed abnormally high levels of methane and benzene in the soil of the neighborhood, with concentrations likely to increase the risk of cancer and cause neurological problems.

Since 1924, the oil company had been storing crude oil in huge concrete tanks, partly buried. "The tanks were summarily destroyed before the sale of the land by Shell in 1966, without being completely emptied or cleaned, and the site was covered with barely a meter of earth, whereas at the time the toxicity of benzene was widely known", explains Tom Girardi, the lawyer for more than 200 residents, alerted by Erin Brockovich (heroine of another fight against chemical contamination, interpreted in the cinema by Julia Roberts). "What Shell did in Carson is far worse than what BP is doing in the Gulf!" The oil boom, of which Southern California was one of the epicentres, is thus coming back to haunt its residents.

Damp and black earth

Shell has advised residents not to eat fruit from their trees or vegetables from the vegetable garden, to minimize contact with the ground (including for pets), and not to let children play in the garden. The situation is catastrophic for these owners who cannot sell their house whose real estate value has fallen.

Investigators unearthed damp, black earth that smelled of petrol, in the garden of Lourdes Piazza, 47, whose two daughters suffer from chronic allergies: "It's torture to think that you live above about that," she said, crying. "Shell needs to take responsibility, and help us out of this!" The contamination was discovered by chance in 2008, during an inspection of a former chemical plant, which revealed concentrations of benzene, coming from the adjacent site, that of Shell.

Representatives of the oil company maintain that the decontamination was the responsibility of the purchaser (the real estate developer), and that the pollution could have other causes: motor oils thrown by drivers, lawn mowers, or pesticides. But for the residents of Carson, Shell must decontaminate the site, compensate them and relocate them. The legal battle comes next.

The safety of offshore oil drilling is well worth a moratorium, Le Monde, 25/06/10, 17:09 p.m.
Christopher Swann and James Pethotoukis

The feeling that the disaster in the Gulf of Mexico is due to BP's lack of professionalism is confirmed day by day, it seems less and less necessary to sanction all players in the oil sector. However, the suspension of offshore drilling decreed by US President Barack Obama is far from useless, even if its legality is questioned. Companies must improve their emergency plans in the event of a leak and public authorities must be able to exercise control. The loss of production caused is a modest price to pay.

The oil sector will not have been long in rebelling. Opponents of the six-month moratorium decided in Washington won a legal victory when a judge declared it invalid. The case is on appeal, but companies that show seriousness can legitimately feel wronged. This prohibition infringes their property rights and unfairly affects their contractual responsibilities.

public interest

On the other hand, the public interest is at stake. Many questions remain. The blowout preventer still lies at the bottom of the ocean. Until the causes of its failure have been established, it will be difficult to correct its technical characteristics. However, BP is not the only company to use the risky method of "expandable tubing". Since mid-2003, about a quarter of operators on the high seas have used this technique.
Anyone who lives along the coasts bordering the Gulf of Mexico has also the right to be moved that the competent oversight body - formerly known as the Mineral Management Service - has been able to endorse procedures that some comparable companies a BP do not consider very sure. It will not be easy to metamorphose this pup won over to the interests of the sector into a feared and respected guard dog.
Moreover, the limited financial loss suffered by the oil industry should encourage it to work on improving its emergency measures. The boss of Exxon Mobil in person recognized in front of the members of Congress that his group was "not very well armed" to deal with leaks in deep waters. Coastal dwellers would do well to demand that companies take more precautions while they are still in a weak position.

It is certain that the moratorium will not be without damage: companies and individuals may find themselves victims of collateral damage. But the quantification of its impact on the whole economy put forward by the stakeholders seems exaggerated. More realistic analyses, such as that of JP Morgan, estimate that a six-month shutdown will cost 300 barrels in 000, the equivalent of 2011% of national production. An acceptable sacrifice, when it comes to improving disaster prevention in the marine environment.

In 2011, we will get used to bathing in oil pellets on the Atlantic beaches, like when I learned to windsurf in Villefranche sur mer in 1978 with my children and we didn't talk about it then !!!!
