Hibernia is an oil field in the North Atlantic Ocean, approximately 315 kilometres (196 mi) east-southeast of St. John's, Newfoundland, Canada, in 80 m of water.
The production platform Hibernia is the world's largest oil platform (by weight) and consists of a 37,000 t (41,000 short tons) integrated topsides facility mounted on a 600,000 t (660,000 short tons) gravity base structure. The platform was towed to its final site, and 450,000 t (500,000 short tons) of solid ballast were added to secure it in place. Inside the gravity base structure are storage tanks for 1.2 million barrels (190,000 m3) of crude oil.
The field was discovered in 1979 with the Hibernia P-15 well, and is located on the Grand Banks of Newfoundland in the northwest sector of the Jeanne d'Arc Basin, the Cretaceous primary reservoir being the Berriasian and Valanginian age river delta Hibernia sandstones at a depth of 3720 m, structurally trapped in a faulted anticline. A secondary reservoir consists of the Barremian to Albian age Ben Nevis/Avalon sandstones at a depth of 2345 m. The Hibernia structure is bounded on the west by the north-northeast trending listric Murre Fault and on the northeast by the Nautilus Fault. Late Jurassic shales, Kimmeridgian/Oxfordian, are the source rocks. Pressure will be maintained via water injection.
