In the mid-1990s, hydrocarbon exploration in the Danish sector of the North Sea shifted from Mesozoic targets to the lower Cenozoic, particularly in the so-called 'Siri Canyon', an erosional feature incised into the top of the Chalk on the eastern flank of the Central Graben. Intensive drilling activity in subsequent years has provided a wealth of new information concerning the nature of the Cenozoic sedimentary succession in this region and has also illustrated the need for a refined, up-dated lithostratigraphic framework.
This bulletin presents the lithostratigraphy of the marine siliciclastic Palaeogene – Lower Neogene succession of the Danish North Sea. Existing groups (three) and formations (seven) defined elsewhere in the North Sea region are adopted and supplied with reference wells; eleven new members are defined from the Danish North Sea succession.
