Before discuss various methods in blow out prevention, we found it is necessary to make an overview on the damages caused by these accidents. The Atmosphere Atmospheric methane, CH4, is the most abundant organic compound in the atmosphere and an important greenhouse gas at least 20 times more potent than carbon dioxide, CO2. Its atmospheric mixing ratio has more than doubled during the last century. Global Emission estimates for marine seeps are _10–30 Tg yr_ or _13% of natural emissions (E0R 2009). The situation could be even worse if the gas is release from a sour gas well, which contains H2S. Water For the blowout, total gas loss during transit of the water column was 1.11% of the seabed emission. That gas goes directly into water column or ocean. The gas contains mostly methane and various toxic components. Oil spills

Unformatted text preview: When oil is spilled or leaked into in waterways and the ocean, it spreads very quickly with the help of wind and currents. A single gallon of oil can create an oil slick up to a couple of acres in size. When oil starts mixing in water, it can change composition and becomes what's known as "mousse". This is a sticky substance that clings even more to whatever it comes in contact with. Many marine animals don't know to avoid a slick and some fish may even be attracted to it as it can resemble food. Even once the oil appears to have dissipated; it can still lurk beneath the surface of beaches and the sea bed, severely affecting marine organisms that burrow, such as crabs, for literally decades. These burrowing creatures are also food for other animals, so the cycle of poisoning continues for many years....
