In the North Sea, chalk became a reservoir for oil and gas by a combination of fortunate circumstances. Shortly after burial chalk in general has a high porosity, but a low permeability. It is a micropore reservoir. For fluids to enter the pore space, pressure is necessary. North Sea Chalk hydrocarbon fields are all located over thick areas of Kimmeridge and Oxford Clay source rocks on structures which grew during the Tertiary. Structural growth caused fracturing allowing hydrocarbons, which… 
Mass-transport deposits and reservoir quality of Upper Cretaceous Chalk within the German Central Graben, North Sea
The architecture of intra-chalk deposits in the ‘Entenschnabel’ area of the German North Sea is studied based on 3D seismic data. Adapted from seismic reflection characteristics, four types of
Ridge and valley systems in the Upper Cretaceous chalk of the Danish Basin: contourites in an epeiric sea
Abstract Extensive low-lying parts of the NW European craton were flooded during the Late Cretaceous transgression, creating a relatively deep epeiric sea with reduced supply of siliciclastic
3D seismic geomorphology and sedimentology of the Chalk Group, southern Danish North Sea
Abstract: Classically, the North Sea Chalk is interpreted as having been deposited under quiet, homogeneous pelagic conditions with local redeposition in slumps and slides. Recent observations of
Interaction between bottom currents and slope failure in the Late Cretaceous of the southern Danish Central Graben, North Sea
The NW European Chalk Group was deposited in a deep epicontinental sea traditionally conceived as a quiet depositional setting that was only affected by redeposition along structural highs. The
Porosity Evolution in the Chalk: An Example from the Chalk-Type Source Rocks of the Outer Carpathians (Poland)
The development and evolution of pore space in the impure chalk-type source rocks of the Oligocene Grybów Marls (Outer Carpathians, Poland) have been investigated using high-resolution petrographic
Slope failure of chalk channel margins: implications of an Upper Cretaceous mass transport complex, southern England
The importance of mass transport and bottom currents is now widely recognized in the Upper Cretaceous Chalk Group of Northern Europe. The detailed dynamics and interaction of the two phenomena are
Petroleum System Analysis of the Chalk Fields in the Danish and Dutch Sector of the Central Graben, North Sea
The purpose of this MSc thesis is to use seismic and well data to investigate and understand the petroleum system of the many hydrocarbon discoveries found within the chalk layers of the Danish and
Regional hardening of Upper Cretaceous Chalk in eastern England, UK: trace element and stable isotope patterns in the Upper Cenomanian and Turonian Chalk and their significance
The regional hardening of the Late Cenomanian to Early Turonian Chalk of the Northern Province of eastern England has been investigated by examining the pattern of trace elements and stable carbon
