what caused the oil spill in the gulf of mexico to happen
Wellhead blowout
title: Ixtoc I oil spill text: Ixtoc I oil spill Ixtoc I was an exploratory oil well being drilled by the semi-submersible drilling rig "Sedco 135" in the Bay of Campeche of the Gulf of Mexico, about northwest of Ciudad del Carmen, Campeche in waters deep. On 3 June 1979, the well suffered a blowout resulting in one of the largest oil spills in history. Mexico's state-owned oil company Pemex (Petróleos Mexicanos) was drilling a deep oil well when the drilling rig "Sedco 135" lost drilling mud circulation. In modern rotary drilling, mud is circulated down the drill pipe and back up the well bore to title: RESTORE Act text: Gulf Coast. On April 20, 2010, the Deepwater Horizon, an oil rig located in the Gulf of Mexico that was owned by Transocean and drilling for British Petroleum (BP) exploded, killing 11 workers and injuring 16. The rig burned for over a day before it sunk into the gulf on April 22, 2010. Following the explosion, the seafloor oil gusher flowed for 87 days, spilling an estimated 4.9 million barrels of oil into the gulf. The spill resulted in widespread damage to the environment and ecology of the gulf coast states, as well as subsequent economic damage to their tourism title: Gulf of Mexico text: 1979, the "Ixtoc I" oil platform in the Bay of Campeche suffered a blowout leading to a catastrophic explosion, which resulted in a massive oil spill that continued for nine months before the well was finally capped. This was ranked as the largest oil spill in the Gulf of Mexico until the "Deepwater Horizon" oil spill in 2010. On April 20, 2010, the "Deepwater Horizon" oil platform, located in the Mississippi Canyon about off the Louisiana coast, suffered a catastrophic explosion; it sank a day-and-a-half later. It was in the process of being sealed with cement for temporary abandonment, to title: Gulf of Mexico text: avoid environmental problems. Although initial reports indicated that relatively little oil had leaked, by April 24, it was claimed by BP that approximately of oil per day were issuing from the wellhead, about below the surface on the ocean floor. On April 29, the U.S. government revealed that approximately per day, five times the original estimate, were pouring into the Gulf from the wellhead. The resulting oil slick quickly expanded to cover hundreds of square miles of ocean surface, posing a serious threat to marine life and adjacent coastal wetlands, and to the livelihoods of Gulf Coast shrimpers and fishermen. title: GuLF Study text: GuLF Study The GuLF Study, or Gulf Long-term Follow-up Study, is a five-year research project examining the human-health consequences of the "Deepwater Horizon" oil spill in April 2010. The spill followed an explosion on a drilling rig leased by BP, the British oil company, and led to the release of over four million barrels of oil into the Gulf of Mexico, 48 miles off the coast of Louisiana in the United States. The study was set up in June that year by the United States Department of Health and Human Services. It is being conducted by the National Institute of
