The eastern Gulf of Mexico shelf area comprises approximately 35% of total production,
primarily within the Main Pass 61 and South Pass 49 & 89 fields.
Main Pass Complex
Main Pass 61 is an oil field located near the mouth of the Mississippi River in approximately 90 feet of water on Outer Continental Shelf (''OCS'') blocks Main Pass 60, 61, 62 and 63. The field includes two black oil producing reservoirs that are being water-flooded to maximize recovery. Energy XXI serves as the operator at Main Pass 61 and has a 100% working interest. The field was discovered by Pogo in 2000, and has produced in excess of 45 million BOE since production first began in 2002, from four Upper Miocene sands. Energy XXI has a 100% working interest and operates the Main Pass 72/73/74 fields, in close proximity to the Main Pass 61 field. Production is from Upper Miocene sands ranging in depths from 5,000 to 12,500 feet. These oil fields have produced more than 100 million BOE to date.
South Pass 49
We have a 100% working interest and operate the South Pass 49 field which is located near the mouth of the Mississippi River in approximately 300 feet of water. The field produces from Discorbis 69 and Discorbis 70 Lower Pliocene sands, ranging in depth from 8,700 to 9,400 feet, on OCS blocks South Pass 33, 48, and 49. We also have a 57% working interest in and operate all sands located at depths above and below the D69/D70 unit. The field is produced from one central production platform, which was shut in throughout 2009 due to damage sustained by third-party pipelines during Hurricane Gustav in late 2008 and returned to service in February 2010.
South Pass 89
South Pass 89 was discovered by Humble Oil in 1964 and has produced in excess of 330 million BOE, making it the 11th largest oil field on the Gulf of Mexico shelf. The field is located south of the Mississippi River in approximately 430 feet of water. Energy XXI has a 100% working interest and operates the field.
Viosca Knoll 1003 Field
Viosca Knoll 1003 field, which is operated by Newfield Exploration. is located in 4,482 feet of water and is a one-well field development completed in the Tex W Sand. Our working interest in the field is 33.3%. The well is a subsea tie-back to Viosca Knoll 823 (Virgo Field) located 19.6 miles away. Net proved reserves are 51% oil. First production began in October 2009 and the field's net production for the quarter ended September 30, 2010 averaged 2.5 MBOED.
