BP Plc has dropped “Crazy Horse” as the name for a giant offshore oil discovery in the US Gulf of Mexico out of respect to descendants of the Native American warrior of the same name. The complex of oilfields, estimated to contain at least 1.5 billion barrels of oil, will now be known as “Thunder Horse.” BP said it adopted the new name after the family of the Lakota warrior and spiritual leader made the company aware that use of his name outside of a spiritual context is sacrilegious.
