Main structural elements of the South Viking Graben and its flanks. The extent of the thick Middle-Upper Jurassic graben fill is defined by the limits of the KCF-Draupne Formation. Unshaded areas on the Fladen Ground Spur and Utsira High have pre-Upper Jurassic rocks beneath Cenozoic or Cretaceous strata (with very thin, <approximately 2 m [6.6 ft], KCF-Draupne Formation in a few wells). The locations of Upper Jurassic oil and gas condensate fields within the graben are shown with solid fill. Fields with Cenozoic reservoirs are shown with black outlines; fields and discoveries with Middle Jurassic and older reservoirs are shown with orange outlines. Most faults shown are derived from mapping by some of the current authors, but a few in the southeast portion of the map are from Zanella et al. (2003).
