Appaloosa is an offshore oil field located in the Mississippi Canyon blocks 459, 460, 503, and 504 of the United States sector of the Gulf of Mexico. It is a part of the Greater Longhorn area. The field is developed by the Italian energy company Eni. [1]
Eni submitted an application to drill, complete and test five exploratory wells on the Appaloosa prospect in 2005. Two wells were drilled in 2007 by the Transocean-owned drillship Deepwater Millennium . However, oil was not discovered. In May 2008, oil was discovered by the Transocean-owned semi-submersible drilling rig GSF Celtic Sea The field development was approved in December 2008. A development well is drilled by semi-submersible drilling rig Transocean Amirante . [1]
In June 2010, Eni stopped development of the project due to the Deepwater Horizon oil spill. [2]
The wells will be tied-back to the Corral platform (previously named the Crystal platform). The contract for the tie-back engineering and construction is awarded to Technip. Offshore installations are done by Technip's deepwater pipe-laying ship Deep Blue . [1] [3]
