Summary of the new stratigraphic guide to the Chalk Group in the UK and Norwegian sectors of the North Sea

This brief guide summarizes the updated and unified stratigraphy of the Chalk Group for the UK and Norwegian sectors in the North Sea. The information was presented at the ‘Chalk of the Northern Province’ symposium held in Hull on 12 September 2015. The update rationalizes Chalk Group lithostratigraphy across the North Sea, reducing the need to use unique names for reservoir units, without proper documentation or lack of biostratigraphic and correlative insight
