Delineation of hydrodynamic/geodynamic trapped oil in low permeability chalk

摘要

The present paper describes the basis for delineating a significant volume of non-structurally trapped oil within low permeable chalk at the flank of the mature Dan field offshore Denmark. Drilling of extensive long horizontal wells at the flank of the main field, including one that set a world record horizontal section, has resulted in the discovery of a thin high porous (>30
