Field-trips

  • Feel the chalk
  • Compare it to your own reservoir rock
  • Combine with core workshop

the chalk cliff at stevs

Stevns Klint

40 km south of Copenhagen. Upper Maastrichtian chalk, the K/T boundary, and overlying lower Danian bryozoan limestone. Single-day visit is rewarding.

  • Analogue flow properties in high-porosity, low-permeability chalk
  • Litho-facies and trace-fossil assemblages

Other localities:

Rørdal near Ålborg, Northern Jutland. Lower Maastrichtian chalk with cyclic deposition.

Laegerdorf near Hamburg, Germany. Fracture system in chalk overlying salt diapir.

Etretat, Normandy, France. Large-scale slumps and slide geometries.
