[Canada] Hibernia

At 1.3 million tons, Hibernia in Canada is the world's heaviest offshore oil platform. It takes a lot to stand up to sea and ice.

Hibernia was the name given by Mobil Oil Canada to a large structural prospect located on its exploration acreage on the Grand Banks of Newfoundland & Labrador. The prospect, a buried anticline, was identified on the western margin of the Jeanne d'Arc Basin by company geophysicists through study of marine seismic data collected in the late 1960's and the 1970's.

When the structure was drilled in 1979 by Chevron Canada and its partners of that time (Mobil, Gulf, Suncor and Columbia Gas), the discovery well had been christened Hibernia P-15. The giant oil and gas field has since been known as Hibernia and application of the name has been extended to include the Hibernia production platform. However, there is more to the name Hibernia than just this recent useage.

The term Hibernia has also been applied to the main hydrocarbon-bearing sandstone reservoir penetrated by the Chevron et al. Hibernia P-15 well. This useage was first introduced in a refereed paper by Arthur et al.(1982). The lithostratigraphic unit Hibernia was at first given informal member status and considered to be a component of the Missisauga Formation. The latter term was introduced by Jansa and Wade (1975) who applied it to a thick sandstone-dominated interval of Upper Jurassic to Lower Cretaceous strata widely encountered on the Scotian Shelf and southern Grand Banks. The term Hibernia was later given formal formation status by McAlpine (1990) and therein redefined as

"the sandstone-dominated unit occuring between the underlying Fortune Bay Shale and the overlying Whiterose Shale or alternatively the overlying "B" marker."
