The offshore heavy oil field, discovered in 1980 in the Jeanne d’Arc Basin, is estimated to contain 700MMbbl of recoverable resources. The Hebron platform, located about 200mi offshore Newfoundland and Labrador in 300ft of water, consists of a stand-alone gravity-based structure (GBS) supporting an integrated topsides deck that includes living quarters and drilling and production facilities. The GBS has a reinforced concrete structure designed to withstand sea ice, icebergs and meteorological and oceanographic conditions. The platform has oil storage capacity of 1.2MMbbls.
Engineering, construction and start-up of the Hebron project took eight years, and involved over 40 million man hours. ExxonMobil previously credited its experience developing the Hibernia project, also located in the harsh Arctic-like environment offshore Newfoundland and Labrador, to helping it shape its Hebron development plan.
The 20°API crude oil Hebron project has involved the development of three fields: Hebron, West Ben Nevis, and Ben Nevis, which housed Hebron’s initial oil discovery. Hebron will tap four reservoir intervals, which are structured into several normal fault-bounded fault blocks. The four reservoirs, which are vertically stacked with multiple fault blocks, are the Late Jurassic Jeanne d’Arc formation, the Early Cretaceous Hibernia formation, the Early Cretaceous Avalon formation and Early Cretaceous Ben Nevis formation.
ExxonMobil affiliate ExxonMobil Canada Properties is operator of the Hebron project with 35.5% equity interest. Partners are Chevron Canada (29.6%), Suncor Energy (21%), Statoil Canada (9%) and Nalcor Energy-Oil and Gas (4.9%).
