Figure 3.
The geographical extent of the distribution of fields classified by reservoir age and size with the field volumes illustrated by relative diameter of the circles. Fifteen of the rift’s fields contain recoverable reserves of more than 1 billion BOE (BBOE), and a further 10 have recoverable reserves in excess of 700 million BOE (MMBOE). Seven of the largest fields sit in the Norwegian Sector: Troll, which contains more than 11 BBOE, Ekofisk (4.6 billion [B] barrels), Statfjord (4.4B), Oseberg (3.4B), Johan Sverdrup (2.7B), Gullfaks (2.5B), and Snorre (2B). The other three lie in the United Kingdom sector: Forties (2.9M), Brent (2.7B), and Ninian (1.3B). As well as showing where the largest fields reside, the diagram serves to demonstrate that the fields hosting Middle Jurassic reservoirs dominate the North Viking Graben and Paleocene ones are the most significant in the Central Graben. The mapped extent of the Upper Jurassic Humber Group sourced petroleum system and the Devonian-sourced “outliers” in the Inner Moray Firth rift arm and Egersund Basin are highlighted. 2P = proven plus probable reserves.
