In late 2012, a study from Georgia Tech and Universidad Autonoma de Aguascalientes in Environmental Pollution journal reported that Corexit used during the BP oil spill had increased the toxicity of the oil by up to 52 times. The study looked at the effects of the oil–Corexit combination on rotifers, which form the base of the food chain ...
If the drill pipe is in the well, the pipe rams slide perpendicular to the pipe, closing around it to form a tight seal. The annular preventers also close around the pipe, but have more of a vertical motion, so they loosen slightly if the drill pipe is being pushed downward, as might be necessary in a "snubbing" or "well kill" operation.

An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters , but spills may also occur on land.
The spill occurred 1 mile northwest of Falls City, Karnes County, Texas, and entered Marcelinas Creek at flood stage. The spill was generally contained about three miles downstream. The floodwaters transported the oil laterally well beyond the banks of the creek, coating vegetation in these areas with oil as the floodwaters receded.
Pemex contracted Conair Aviation to spray the chemical dispersant Corexit 9527 on the oil. A total of 493 aerial missions were flown, treating 1,100 square miles (2,800 km 2) of oil slick. Dispersants were not used in the U.S. area of the spill because of the dispersant's inability to treat weathered oil.
The impact sent pieces of the bridge, which connects Galveston to Pelican Island, tumbling on top of the barge and shut down a stretch of waterway so crews could clean up the spill. The accident ...
