If the hydrostatic head of the drilling fluid is insufficient to control subsurface pressure, formation fluids will flow into the well. To maintain well control, back pressure is applied by routing the returns throug.
[pdf] Deepwater drilling, or deep well drilling, is the process of creating holes in the Earth's crust using a drilling rig for oil extraction under the deep sea. There are approximately 3400 deepwater wells in the Gulf of Mexico with depths greater than 150 meters. Deepwater drilling has not been technologically or economically feasible for many years, but with rising oil prices, more companies are investin. 2010 Deepwater Horizon oil spillOn 20 April 2010, a deepwater oil rig () exploded, killing 11 and releasing 750,000 cubic meters (200 million gallons) of oil into the Gulf of Mexico. With those numbers, many scientists c. .
Drilling in deep waters can be performed by two main types of mobile deepwater drilling rigs: drilling rigs and . Drilling can also be performed from a fixed-position installation such as a fixed platfor.
