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 1,300 to 5,000 feet (400 to 1,520 m),) was discovered in September 2009 and it is operated by BP. Described as a "giant" find, it is estimated to contain 4 to 6 billion barrels (640×10^⁶ to 950×10^⁶ m³) of oil in place. Although BP states it is too early to be sure of the size – a "huge" field is usually considered to contain 250 million barrels (40×10^⁶ m³).
