The sedimentology of redeposited chalk

Kresten Anderskouv; Finn Surlyk; Andy Gale

Abstract

Redeposited facies in the Upper Cretaceous Chalk Group constitute major hydrocarbon reservoirs in the North Sea Central Graben. Existing facies models are largely based on publications from the early 1980's dealing with core material from the Norwegian sector. However, the recognition, interpretation, and predictability of redeposited chalk facies remain uncertain. This project aims to improve existing facies models by investigating and comparing redeposited chalk units from a variety of settings. Long cores from the Danish and British sectors are interpreted in terms of depositional process and facies-porosity relation. These interpretations are integrated with a seismic investigation of the study areas (phd project by Janus Bruun Christiansen). Outcrops showing large-scale remobilization in the Upper Cretaceous chalk of southern UK are investigated to document possible source mechanisms for redeposition of chalk. This leads to an integrated scheme covering most aspects of chalk redeposition.
