Seismic stratigraphic complexes of the Lower Cretaceous in the Barents sea

Abstract

The Lower Cretaceous strata are the least studied succession which was penetrated by wells in the Barents Sea. Investigation of the geological structure of the Lower Cretaceous is based on the principles of seismic and cyclic stratigraphy. The recognized complexes and sequences are considered as the main sedimentary complexes, formed during different stages of geological evolution of region, and have different hydrocarbon perspectives. Neocomian strata are charactertized by clinoform structure. Detail analysis of geometry and sizes of clinoforms allowed to classify and find out sedimentary conditions.
