South Viking Graben & Utsira High Stratigraphic Database

The South Viking Graben and Utsira High Stratigraphic Database comprises of a 75 well dataset that encom- passes the majority of the fields and hydrocarbon discoveries from this part of the North Sea Basin.

Of particular note within the database are the high profile discoveries for the Greig area (Luno) together with offset wells close to the Johan Sverdrup area (Avaldsnes – Aldous). The stratigraphic interval includes the Tertiary – Triassic (and basement) including all the main hydrocarbon bearing intervals.

The study utilises the Ichron sequences which are calibrated with the North Sea lithostratigraphic nomenclature and also incorporates the Norlex terminology.
