in the review of the week you know it's battling terrorism and drug trafficking is on the agenda of a summit in russia seaside resorts and century president leaders of afghanistan want to start intensity stuff and together to discuss how to bring about peace in central asia. iran starts pumping flew into the country's first entry into the southern city the ship the russian don't react to is being closely monitored you won't see it once told that the star producing

a christie will be in the can be a. big government says it will have the final say on the fate of the lead russian arms do that because. that's all from an escape route and has to be extradited to the it's decision day as political. defeat for inspectors review whether russia is better suited to perform company twenty. two another bit is the strongest feature india went in the decision which will be announced on december the second in syria. while the oil spill in the gulf of mexico has cost billions of dollars to clean up but the true cost to the environment isn't well she looks now it's whether the black gold is worth such a high price. the explosion of one. of mexico's done the entire world according to various estimates six to

fifteen million liters of oil clues to the water each day for three and a half months in the soviet union underground nuclear explosions were used to deal with leaking whelps they stem the flow of oil within a short period of time. nuclear explosion is safe and very effective economically a different method has been used in the gulf of mexico installed a special cap on the leaking pipe the task now is to skim the oil slick which now covers nearly two thirds of the gulf surface some one million square kilometers one tenth of the oil spilled has formed this slick even if engineers eventually succeed in skimming oil from the surface approximately five hundred million liters of oil will remain on the ocean floor and in various steps it's not the first time such a catastrophe has occurred what prices humankind ready to pay for the world's most widely used fossil fuel is it possible to prevent these disasters in the future

aftermath of such oil spills be dealt with quickly and effectively. the world's reserves of oil are running out to keep it flowing more drilling rigs are being open with each passing year. each new oil field. under water requires more sophisticated production methods. the more difficult the process the higher the risks the gulf of mexico oil spill is a strike. by a number of technological. as it turns out all existing methods of stemming the flow of oil do not work in

a crisis situation the set of measures available today is simply. an ecologist he was a member of an official international delegation invited to mexico in early june two thousand and ten. the russian specialist told the mexican government and united states senators about their proposals on how to block the leaking wellhead. specialists spoke of a concrete solution. in the past they used nuclear explosions still to spread of fires on oil fields. they presented the set of techniques which could be applied to the leaking wellhead. underground explosion was used on august tenth one thousand nine hundred seventy two to deal with an accident on a major gas field near the village of. eastern ukraine many of the villagers employed at the oil derricks four hundred metres from where it was extracted when

they were drilling a new will to add to the thirty four already in use gas suddenly gushed out under enormous pressure that. was relaxing after a day's work. it was a run of the mill drilling procedure. nearly reached the guess where. there was a very low noise. come from. so i was totally confused. has hardly ever left the village where he was born. the accident at the well occurred during a test drilling. close to his heart three of his good work mates had died there. store a huge plume of gas and condensed steam gushed out of the well. to all the pipes that were pushed into this if it. fell on the hill

a long distance away. they were twisted like coil b. only. an emergency team was immediately dispatched to the scene but was unable to cope with the incredibly high pressure of gas inside the well which approached five hundred atmospheres. think yassin steam came from the. they rose up to the sky and then rained down on the grass and vegetable gold. everything in the soil. and this stuff was went lying to you and it was. as if somebody has spilled diesel fuel the precipitation poisoned everything around they set light to the gas escaping from the well and the most harmful substances were burnt in the flames and then just the crew still has vivid memories of the roaring gas torch scientists estimated it was one hundred meters.

or a flame was right there. it could be seen from far. there was as much light at night is during the day and the noise was so lounge we couldn't tell it was terrible very young they couldn't sleep at night the noise made them tremble. it was then decided to use an underground nuclear explosion the method had been tested that would deposit. back in one nine hundred sixty six the situation there was compounded by the fact that the malfunctioning well was not the only source of gushing gas. there was a sudden pressure surge. straight. rangers amounts of fire began basically. already being populated area. the operation was caught on film scientists put together

a four minute tape later they took a. pride in showing it to the rest of the world the plan looks simple enough another well is drilled next to the one weekend where a nuclear charges placed. on project materials ready. to sink in deep shock. to the gas well. could be set off in plastic geological material. asking permeable straight. a bit of a silly if is the scientist specializing in physics and mathematics he's devoted himself to studying and making nuclear charges for peaceful purposes these bombs contain special isotopes which have a short half life. guess products are very dangerous but they also are short lived

this means that their radioactivity goes down quickly means that we've never contaminated anything in. the nuclear physicist knows how difficult it is to pinpoint exactly where the end of a new well will be when dealing with depths of more than a kilometer. yet given that it was a nuclear explosion of those for an air of thirty to forty meters between the wells the distance is enough for an explosion to pinch the well but the. depth was around fifteen hundred meters as we needed to approach the troubled well at that depth as close as we call sibley could. so that's what we did let me put the flames out thanks go to. the underground explosion triggered a small scale earthquake as a result the shelves began to move squeezing the shaft shut. come in explosives are

not powerful enough to achieve this. and. the explosion formed a hollow underground sphere with a radius of twenty to forty meters the newly hardened molten rock created a natural tune for the radioactive waste this shaft has been successfully blocked and gas is no longer leaking supervisors found no trace of radiation either in the air or on the ground nuclear material ended up buried at a depth of one thousand five hundred meters.

the. division. has. four months of preparation as a. monster minus. the last effort to keep the lead on the eastern front plead citadel of funds to play. mom had a great sacrifice of luck. and looms are still. some advantage of people military partly. the most heavily reinforced.

battle of course. it lasted forty nine days one of them bloodiest battles and the turning point a move to push. just

. species of fish and microorganisms huge interest to biologists the next research expedition for two deep submergence research vehicles. to. position it. with manipulators that can perform high precision operations underwater and their crude by top professionals. film director james cameron used. to do deep water shooting for his movie titanic he also suggested the

american government should use these russian submersibles to stop the oil spill in the gulf of mexico because cameron is convinced that meters are the best of their kind in the world. would have needed to. express his wish. they would have been happy to help. russian specialists who took part in the deepwater shooting for titanic. to stop the oil spill. it would have to be done with the workers. and how it must be handled there would have to be. key advantage in this project.

any project is interesting and this one is special because it deals with a disaster that affects the whole world and so we would never refuse from taking up such a task with. deep submergence research vehicles a mere one in me or two could have fitted to stop or on the oil spilling pipe in the gulf of mexico. now that the oil company has finally succeeded in doing so on its own another problem arises how would they clean up thousands of tons of oil dispersed in the ocean mir's are unique in that they're compatible with any kind of manipulators. there's a huge amount of oil is seabed imagine a vacuum cleaner just like the one you have a new york both meant and if you use that on the seabed it will suck in all resting to. suck in almost all of it but the question is what you do with the residue today

there are technologies that can remove the remaining oil whether it's on the surface or a mile under water. and holds a degree in biology and is the founder of the international environmental and social committee he has consulted most of the domestic and foreign oil and gas companies operating in russia but business circles don't seem to be in a hurry to take his advice. we have to kill it is capable of cleaning up the. production but they're expensive. and would cause the end of the product to soar well we're always trying to make it as low as possible. dispersed in ocean water has no commercial value cleaning devices used to soak it up from the surface of the gulf of mexico need to be somehow. a research lab and has come up with an unexpected solution. you know quite

a number of months or organisms. two hundred feet on patrol in one hundred. the research is trying to make use of this amazing ability just as. the researchers have developed a new population of salt resistant microorganisms that feed. breaking it down into components that are harmless to the environment. the final product of hydrocarbon breakdown are carbon dioxide and water but it is a gradual process after several years of laboratory tests scientists have decided to publish their results microorganisms begin to interact with the oil spill spreading on the bay in front of our eyes future pollution control will be exercised naturally without human intervention the only serious drawback of this

method is that it's very time consuming. we have already seen the first environmental effect that we were trying to prevent the spread of the oil. it has been localized and the destruction of the spill will take from a few weeks to several months to be. currently microorganisms are a bulky expensive yet very effective method for the final stage of an oil spill cleanup when the leaking well has been stopped up and most of the oil has been collected. the most effective way to this day is the collection of oil from the water. we need to develop a strategy. beach the shoreline because if that happens. to work in creases drastically. today eager to say you can is responsible for the technical any ecological safety of the activities

and operations of one of russia's largest oil companies. he thinks the most dangerous situation is when drilling of new bore holes coincides with repair work. hole is open in any human can lead to a terrible terrible exhaust. in the gulf of mexico the catastrophe actually happened right in the moment of drilling. and on our platforms we use the so-called equipment used to. help the totally block the bore. and this is actually control. person who doesn't have to be near it. the main task in case of any

accident is to cut off the uncontrolled release of oil or gas as soon as possible. problem was solved in the summer of one thousand nine hundred eighty two on one of the fields near the village of part of my sky in eastern ukraine an accident occurred four hundred meters away from the settlement by an oil derrick gas under tremendous pressure burst from the ground. very helpful for the environment especially if this hydrogen sulfide. every living thing around this building to which kills flowing to the. nuclear explosion is an environmentally friendly method which is very cost effective. and everything has been. to specialize in transporting especially heavy cargo pensioner he remembers all too

clearly the day he transported a nuclear bomb to an oil well near the village of pet of my sky. i came to work they told me to go to the railway station. had a container proximately was size of a large safe loaded on. to that for soldiers with machine guns to get in there with a major got inside. at that time he didn't have a clue about what kind of cargo he was taking to the rig. he became suspicious a couple days later when all of the villages were evacuated from the neighboring town while he and other drillers set up according to kilometers from the mine. shaft and the flame begins to go down until it became.

moments everyone started because the will was killed already but the fire started up again and continued. i was born here he's now a professor of physics at a major university. in the summer of one thousand nine hundred two the scientists to be at home on vacation in voluntarily a witness to an accident and the attempts to fix it. approximately one hundred meters to the north of here. and a charge was put into. it was located twenty meters from the rake. of about three and a half kilometers. later on recheck the calculations of the moscow scientists several times and studied all the peculiarities of the entire operation. explosion

was set off ten am. the weather was just as hot as a nine hundred seventy since that all the strength of the explosion was three point eight. in comparison with the bombs dropped on hiroshima and nagasaki approximately six times more powerful the explosion was to be set off in a heavily populated area in the european part of the country as a result its capacity was reduced to the minimum so the clamping links appeared to be too little and the gas made its way to disservice via cracks in the earth. would increase the capacity by three times while the distance remained the same. carried out special calculations and found. six times for this particular. and therefore it was necessary to either come close. to the challenged of course increasing the strength of the explosion is always easier and safer. because of

their concerns about the consequences the ukrainian operation was not successful in total the soviet union carried out five nuclear explosions to overlap five different emergency mines three of them were complete successes. summarizing the experience of past years at the end of may two thousand and ten russian scientists developed a fast and reliable way to eliminate the consequences of the accident in the gulf of mexico using conventional explosives instead of nuclear once you know that it's a bill first it was proposed to put a bunch of charges inside the flowing well of course the charges diameter would be smaller than the well itself some. several more wells are drilled in parallel and a large number of explosives are stored there. first the charges laid out in the very loyal wells are detonated thus in certain

places a pipe is destroyed and voids are formed simultaneously now and dense and big oil will not be hampering the blowing up of the very surface of the pipe and. the breaks formed are immediately filled up with rock from the bottom that's how the well is sealed. oil pressure in the pipe me move one of the created plugs but since there are several of them they'll be able to hold the flow of crude oil. this is just one of the possible ways of containing a rapid oil spill but they need to be adapted depending on specific extraction conditions. likewise postville clean them and its must also become more various and more flexible as the world learned in the gulf of mexico tomorrow may

be too late. every month we give you the future we hope you understand how to get there and want to bring the best in science and technology from across russia and around the world join us for technology update on r g. more news today violence has once again flared up. and these are the images the world has been seeing from the streets of canada. china operation to rule the day.

come. come. come. come up. come undone come. this astri still keeps its secrets but now it's time to move feel. the soviet fines on oxy some. wealthy british style. sometimes. margetts why not scandal. find out what's really happening to the global economy.
