Hebron felds are expected to produce 80% of the 20°API heavy oil on the project. Oil production capacity is planned for 119,506 to 176,115 b/d with treating capacity of 188,694 to 283,041 b/d of produced water for disposal overboard. Gas will be com- pressed at a rate of 53.0 to 70.6 MMcf/d.

Storage capacity is 1.45 MMbbl.
