16 Aug 2013 Tyson Cornfield has been working on oil rigs in northern Canada for five years. He'll answer questions today from 2pm to 4pm ET. Oil Field Image Gallery Offshore oil platform 'Gullfaks C' stands up to a fierce, North Sea storm. In this part of the world, waves frequently reach as high as 6 feet (2 meters). In this part of the world, waves frequently reach as high as 6 feet (2 meters). Sea water or other liquid is then pumped from the vessel down through the drill pipe and is jetted out of the nuzzles on the drill bit. This liquid current forces the cuttings up to the sea floor. That is Rotary Drilling. Riser System. The deep sea drilling vessel Chikyu can drill over 7 kilometers below the sea floor into the earth. The Deepwater Horizon was something like 300-by-300 feet, with a drilling derrick 220 to 230 feet high and designed to drill in very deep water, up to about 7,000 feet.

Oil spills also hinder the breathing progress of sharks and rays, clogging their gills and potentially suffocating them. Animals that depend on fur to keep warm, like sea otters and polar bears, are often the most immediately impacted by oil pollution, many dying from hypothermia after their coat is covered in oil.

Deepwater drilling, or Deep well drilling, is the process of creating holes by drilling rig for oil mining in deep sea. There are approximately 3400 deepwater wells in the Gulf of Mexico with depths greater than 150 meters. It has not been technologically and economically feasible for many years,

Today anything above 15oo feet (500 mts) is usually referred to as Deep Water; anything deeper than 1500 mts (4500 ft) that is referred to as Ultra Deep Water. The Gulf of Mexico projects can drill in waters up to 5000 ft of water; Brazilian pre-salt can probably go deeper -2000 mts or more-.
