Abstract

The Norwegian Central graben and northern Viking graben are among the most prolific hydrocarbon provinces in Europe, with proved reserves exceeding 8 billion bbl of oil and 61 tcf of gas. Although are several successful plays are found in both grabens, this study concentrates on factors controlling accumulations in the most prolific trends - the Late Cretaceous to Danian chalk fields of the Central graben, and the Jurassic and Triassic sandstone fields of the northern Viking graben. Detailed modeling of hydrocarbon generation and migration in the two grabens demonstrates some similarities and major differences in the geochemical factors that control the accumulations.
