What is an oil riser?

In Brief...

On April 20, 2010 a methane bubble escaped into a drilling pipe, got past the malfunctioning blowout preventers and shot up the drill pipe to the Deepwater Horizon, causing an series of explosions that killed 11 workers and toppled the rig over 5,000 feet to the seafloor below. The effect has been a?catastrophic? crude oil leak into the Gulf of Mexico, from three different places on the?subsea formation. It has auxiliary lines that circulate fluids to the BOPs located near the seafloor as well as other auxiliary lines that contain the power and controls to the BOPs. The use of, and movement around, a riser is an intricate process that requires alot of engineering and analysis. Thus far in the 2010 Gulf of Mexico oil spill the leak has not been contained though some sources believe that the riser which is leaking is bent and crimped from the force of the rig falling on it, stemming some of the flow of oil.
