Offshore oil field
the production platform

Thunder Horse oil field is a large offshore deepwater oil field in the Gulf of Mexico, around 150 mile (241 km) southeast of New Orleans, Louisiana. Large new oil discoveries within it were announced in early 2019.

The field is being developed by BP plc and 25% partner ExxonMobil It is the largest offshore production platform in the Gulf, with a processing capacity of of oil and of natural gas, and the field is believed to hold in excess of of oil. Actual production approached capacity in March 2009, but started to decline soon after that. In January 2019, BP announced a new billion barrels of oil have been found within the field.

The Thunder Horse discovery well was drilled in 1999 on Mississippi Canyon block 778. It was drilled to a depth of 25770 feet (7855 m) from the drillship Discoverer 534, hitting three intervals of oil. A second well was drilled in block 822, 1.5 mile (2 km) southeast of the initial discovery, reaching a depth of 29000 feet (8839 m) in November 2000 and also encountered three primary intervals of oil. In February 2001 a new field known as Thunder Horse North was drilled in block 776, approximately 5 miles northwest of the original field. This well reached 26000 feet (7925 m) and again met three intervals of oil. Actually developing the field was a major technological challenge due to the depth of the find. Not only are the distances large, but at such depths the formations holding the hydrocarbons create pressures over and temperatures of Prior to Thunder Horse, no field had ever been developed at such a depth. Following lengthy delays caused by the need to repair and replace components in the subsea system (following a failure during pre commissioning checks), "First oil" came on June 14, 2008. Since then, Thunder Horse has steadily ramped up its production by bringing on new wells. In March 2009, Thunder Horse produced close to oil equivalent in oil and natural gas from seven wells. Plans were in place to add two additional wells in 2009 to further develop the north end of the field. By January 2010 the MMS data indicated that total daily production during 2009 had declined from near The Washington Post noted in May 2010 that "There could be less off shore oil than the [Obama] administration assumes" quoting an analysis in The Oil Drum by Glenn Morton, a consultant for oil exploration projects who stated that "Thunder Horse hasn't reached anywhere near its expected potential," in oil or natural gas a fact which "underscore[s] the point that deepwater oil drilling is a tricky process, and not always as easy or predictable as thought" By January 2022, Thunder Horse was again producing 200,000 barrels of oil equivalent per day.

Thunder Horse PDQ is the largest moored semi submersible production oil platform in the world, located in of water in the Mississippi Canyon Block 778/822, about 150 mile (241 km) southeast of New Orleans. The hull section was constructed by DSME in South Korea and delivered in to Kiewit Offshore Services in Ingleside, Texas on 23 September 2004 aboard MV Blue Marlin for completion. Thunder Horse was completed at Kiewit Offshore Services in nearby Ingleside, Texas. Thunder Horse PDQ was evacuated with the approach of Hurricane Dennis in July 2005. After the hurricane passed, the platform was listing badly. The platform was designed for a 100 year event, and inspection teams found no hull damage, and no water was taken on from a leak through its hull. Rather, an incorrectly plumbed, 6 inch length of pipe allowed water to flow freely among several ballast tanks that set forth a chain of events causing the platform to tip into the water. The platform was fully righted about a week after Dennis, delaying commercial production initially scheduled for late 2005. During repairs, it was discovered that the underwater manifold was severely cracked due to poorly welded pipes. The rig's design engineer, Gordon Aaker, said that the cracked manifold could have caused a catastrophic oil spill. The platform took a near direct hit six weeks later by Hurricane Katrina, but was undamaged.

Originally called Crazy Horse, BP changed the name out of respect to descendants of the Native American warrior of the same name. The company said that it acted after the family of the Lakota warrior and spiritual leader told them that use of his name outside of a spiritual context is sacrilegious.
