Petroleum potential and depositional environments of Middle Jurassic coals and non-marine deposits, Danish Central Graben, with special reference to the Søgne Basin

The presence of hydrocarbons with typical terrestrial geochemical signatures in the Danish Central Graben has made the search for petroleum-prone terrestrial source rock and intriguing question.

This bulletin gives a comprehensive account of Middle Jurassic coals and carbonaceous mudstones in the Danish sector of the North Sea, particularly those of the Bryne Formation. A multidisciplinary approach incorporating organic petrography and geochemistry, sedimentologu and sequence stratigraphy, provides strong evidence for the petroleum-proneness of the coals and for the close relationship between generative capacity and depositional environment.
