Production and handling

The constituent fields Diana (East Breaks 9945, 946, 988 & 989), South Diana (Alaminos Canyon 65), Hoover (Alaminos Canyon 25 & 26), Marshall (East Breaks 949), and Madison (Alaminos Canyon 24 & 25) are located approximately 150 miles offshore Galveston in the western portion of the Gulf of Mexico. The primary production facilities consist of a Deep-Draft Caisson Vessel (DDCV) in 4,800 feet of water at the Hoover site. Diana, South Diana, Madison, and Marshall production originates several miles away from sub-sea production facilities in over 5000 feet of water which then flows over to the Hoover DDCV where it is commingled with the Hoover volume. Production from Diana began in May 2000 and from Hoover in September 2000. Marshall and Madison production began fourth quarter 2001. South Diana production began approximately fourth quarter 2003.
