But let us take another look. Ideally you would want sand to fuse to glass to create a blockage of glass so that the oil and gas will not come up.
Let us say you detonated an A- bomb on the sea floor bed.
The blast would go up instead of down. It is easier to move water than earth. You might fuse 50 to 100 foot of mud. The 6000 plus pounds per square inch of oil and gas would still come up the hole but now it will be spread out through the mud and will be coming up through the sea bed floor.
Now you detonate your A-bomb. If you look at pictures of A-bomb caverns created after blasts underground they are gigantic voids where the rock was vaporized. You now have a much larger area for the oil and gas to find its way into many more fractures that you created and through the sea floor to the surface. You will never get a homogeneous vast layer of fused glass. It does not happen in nature. There are always cracks. This solution might work if this was not a high pressure well, but if it was low pressure we could let the sea water of 2300 pounds per square inch close the well for us. Remember atmospheric pressure is only 15 pounds per square inch at sea level. This sea water pressure would shut down 99% of all wells on the earth's surface.
What people do not understand in oil and gas drilling is that less than 5% of the world's wells are high pressure oil and gas wells. I want to stress here, that I do not mean great depth wells, in sea water. There are places in California, on land, where new mudlogging geologists would not be sent until they understood about high pressure oil zones. It is a dangerous game drilling into high pressure oil and gas zones because you risk having a blowout if your mud weight is not heavy enough. If you weight up your mud with barium sulfate to a very high level, you risk blowing out the formation. What does that mean? It means you crack the rock deep underground and as the mudweight is now denser than the rock it escapes into the rock in the pore spaces and the fractures. The well empties of mud. If you have not hit high pressure oil or gas at this stage, you are lucky. If you have the oil and gas comes roaring out and you have a blowout, because you have no mud in the well to suppress the oil and gas. You shut down the well with the blowout preventer. If you do not have a blowout preventer, you hope that the oil and gas pressure will naturally fall off with time, otherwise you have to try and put a new blowout preventer in place with oil and gas coming out.
I saw the strain on many company men's faces and those of the mudmen who were responsible for keeping that fine balance between mudweight and not blowing out the formation when I logged in high pressure zones.
THEY WOULD ASK TO BE NOTIFIED IMMEDIATELY THE BACKGROUND GAS UNITS WENT ABOVE 50 UNITS OF GAS OR 1% GAS WHILE DRILLING. Geologists were responsible for logging the geology but more important was watching the background gas, so they could weight up the mud and prevent a blowout. When mud began to flow back out the well under pressure from deep underground, you knew you were losing that well and you would probably have to shut that well down with the blowout preventer and spend weeks getting cement into the well and basically write off the well. The investors who put up the money for the drilling would then be asked to pay more money in for a non functional well
Let us say whoever worked on that well from the geologist to the mudmen to the drilling contractors to the company man to geophysicists who sited the well, their reputation was mud.
Personal history on one blowout well near Sacramento California in 2006.
I was responsible for preventing a blowout just south of Sacramento at 11500 feet when the well began to flow. The company man was an arrogant man and would not believe our instruments for measuring the gas pressures during drilling and therefore would not weight up the mud. I called the offsite petro-engineer to get him to take control away from the company man. I was kicked off the site. The well began to flow and the blowout preventers were actuated to shut down the well. They lost the most productive zone of the well because of the great pressure and only saved the top 8000 feet because it was already cased with steel. It took many weeks to get the well under control. The investors had to pay in more money. I do not know if they ever made a profit, but I think they did, probably after 6 months to a year. Normally you will pay off a land well's cost within two months from the oil and gas flows. That means you have paid off at least $5 million dollars in 2 months and then it is all profit as long as the well keeps producing. It is not surprising that the world is greedy, mad and blind. How can you get the oil companies to convert to solar? Where's the profit?
High PRESSURE wells are not the norm, like this Gulf of Mexico BP one. It is very dangerous and although the rewards are higher, nobody likes working on them. The investors do not care as long as they make a profit.
The company knows the risks and is prepared to sacrifice people and the environment. After all money is money. There are always more people and the environment is the responsibility of somebody else. NO OIL COMPANY CARES ABOUT THE ENVIRONMENT. If they did, they would not be in this business. There is no such thing as clean oil. It is all carcinogenic. It is like asking the tobacco companies to care about your health. You can not ask people with no morals to care. It is hard enough for them to manage the faà §ade of caring. They have learned to keep quiet and say nothing. BP gets all the flack. They deserve a great deal, but spare some for two of our other friends. Where are Transocean and Halliburton? I do not see them standing up to shoulder any of the blame. I guess they are lying low, as usual and counting their loot.
