The catastrophe in the Gulf of Mexico will obviously take a special place in the history of the human civilization. Forward-looking people say that the disaster is a warning of the wrong way of the future development. Others say that it was just an accident which took place through the fault of specialists, who did not provide required conditions for safe exploitation of the oil well.
No matter how we may evaluate the catastrophe, it gives us a reason to think whether humans live and act reasonably and how we use our spiritual and physical gifts. Unfortunately, the conclusions are sad since they show our dullness and thoughtlessness.
It is clear that the measures, which are now being taken to lock the broken pipe, will not bring any result in the nearest future. The pressure of crude and gas is too high, it goes about hundreds of atmospheres. They now hope to contain the leak with the help of steel and concrete domes, but the hopes for that are tiny. It will be extremely difficult to mount the dome: the depth of the gulf is about 1.5 kilometers, and the “orifice” is small. It is impossible to find out what it looks like after the explosion. Crude is supposed to be pumped from the dome to the tanker on the surface of the gulf along a special pipe.
This is a very complicated an unreliable system. As far as I know there was no such an occurrence in the world practice of oil extraction. Therefore, anything can happen, and it is impossible to foresee everything. The oil leak will only strengthen since it is only going to accumulate underneath the dome and geological horizons.
The dome installed above the well will only give a short break in the liquidation of the disastrous consequences. What can be done next ? There are practically no variants because no one has ever done that before in such conditions.
It was only a matter of hit or miss which earlier resulted in the nuclear disaster in Chernobyl, explosions in coal mines all over the world and also in the catastrophes which occur on a regular basis, but are very hard to liquidate. One may say that the American hit or miss has led to one of the most technologically complicated and horrific disasters.
It is practically impossible to block the leaking well. There are neither specific technical possibilities for that, nor any methods to liquidate such oil-well flowing.
The USSR had a sad experience in containing oil-well flowing in Central Asia. Two breakdowns occurred almost simultaneously. One of them took place in Urtabulak, where a gas torch was burning. The other one took place in Pamuk – a breakdown at an oil well. The two giant flames were extinguished with the help of nuclear explosions. They drilled two wells to approach the emergency wells under the ground and lowered nuclear devices into the wells. The troubled wells were blocked as a result of the explosions.
The work was extremely hard, but it was worth it. I took direct participation in the experiment and was personally present there during the explosions. The experiment was a success. The exploitation of the Pamuk oil well was launched again and nothing could remind of the disaster which had been liquidated with the help of nuclear explosions.
Afterwards, Soviet specialists conducted similar experiments in Turkmenia and then proceeded to worked-out deposits. The results were encouraging. Soviet specialists hoped that they could promote their technology to help other countries, the ones that signed the non-proliferation treaty but could use nuclear explosions in industrial purposes.
The US declined the program over the threat of radioactivity. As a result, the Americans offered to ban the use of nuclear explosions in peaceful purposes.
It now seems that a nuclear explosion could be the only way to contain the oil leak in the Gulf of Mexico. It is not ruled out that British and American specialists will find a new solution to liquidate such complicated disasters that, as it turns out, may occur to absolutely reliable platforms.
Extracting oil in oceans and seas has its pluses and minuses. It brings hydrocarbons for the chemical industry and fuel for cars – the cars that continue to conquer the human civilization. It seems that the number of cars in the world will soon be comparable to the number of people living on the planet. It is about time one should realize that cars no longer exist for people – people exist for cars. People fight for parking lots, territory for garages and get traffic jams in return. As a result, we have to pay enormous price for the comfort of movement – we sacrifice our ecology, health and the future of our children.
Oil wells drilled in oceans and seas slowly kill the planet. Thousands of kilometers of oil wells are like bleeding wounds on the surface of the planet. They result in numerous natural disasters – from earthquakes to volcano eruptions.
Oil leaks occur all the time. It will be enough to fly above any pipeline to see that. It is worthy of note that the West helps Russia build its own sea-based oil platforms. We already have several platforms near Sakhalin and will soon have more in the Caspian Sea. What if a similar disaster occurs in Russia too?

Drill Off the Gulf Coast of Florida? - Consider This
Thanks for your letter.
You mentioned the Ixtoc 1 blowout in the Gulf. That spill released over 140 million gallons of crude oil into the Gulf.

This summary explains why environmental impacts were not as great as they could have been. Location and prevailing currents made for a lucky break - there was plenty of time to prepare before the mess came near shore.

Depending on the location of a blowout in the eastern Gulf, plus winds and currents, Florida's coastlines and sea life could be damaged for a generation. See NOAA study here as to oil impacts on mangroves. The only mangrove communities in the continental U.S. are in Florida (the entire west coast of Everglades National Park) and the study explains in detail why this ecological community would be the very worst place any sized spill could happen.

This NOAA image of the Gulf of Mexico shows the basic Loop Current - always subject to change depending on weather conditions:

Offshore drilling in the eastern Gulf near Florida could well be a nightmare waiting to happen. Both the ecology and the economy of Florida would be hit very hard by a major spill. The risk is too great - the rewards much too small.
Finally, see this study which shows how even routine offshore oil drilling operations impact the ecosystem and sea life:
