The Tiber Oil Field is a deepwater offshore oil field located in the Keathley Canyon block 102 of the United States sector of the Gulf of Mexico. The deepwater field (defined as water depth 1300 to 5000 ft,[1]) was discovered in September 2009 and it is operated by BP. Described as a "giant" find, it is estimated to contain 4 to 6 Goilbbl of oil in place.[2][3] Although BP states it is too early to be sure of the size – a "huge" field is usually considered to contain 250 Moilbbl.[2] It required the drilling of a 10685 m deep well under 1260 m of water, making it one of the deepest wells ever drilled at the time of discovery.[4][5]
