In situ stress and natural fractures have been mapped across the structural dome that forms the Ekofisk field in the Norwegian sector of the North Sea. The reservoir rock is chalk and a natural fracture system forms the primary conductive path for produced hydrocarbons and injected fluids. In situ stress measurements have been made using hydraulic fractures and anelastic strain recovery measurements of oriented core. 36 refs., 21 figs., 2 tabs.
