Eriksfiord has its origins in the early exploration for North Sea and North Atlantic hydrocarbon resources, and by extrapolation, our company took its name from the first known settlement of Europeans in North America (986).
In the 1970s the first attempts were made to register borehole geophysical measurements on magnetic tape, which made even densely sampled data accessible to automatic computation. The main orientation of geological surfaces could now be extracted from oriented profiles of electrical conductivity through statistical calculations.
Relating the stream of orientation data to the geological structures penetrated required a geoscience based interpretation methodology. Birger Hansen was entrusted developing one by Statoil in early 1980s. He chose to base it on the symmetry concepts developed by Pierre Curie (1885) and the “statistical symmetry” described by Sander (1930) and Turner and Weiss (1963). It soon turned out that the methods applied equally well to depositional as to deformational structures.
Promoting the methodology required an independent organisation, so in 1985, Hansen joined forces with an outstanding group of software engineers in London, Z&S Consultants Ltd., and formed Z&S Geologi AS to provide services to oil companies based on software later to be marketed as Recall, still constituting the basis of Eriksfiord services. The first employee was structural geologist Christian Gaardboe Ottesen who dedicated his whole carreer to downhole structural interpretation.
Z&S became part of Baker Atlas in 1998, and in 2001, Hansen founded Eriksfiord AS, soon to be joined by Ottesen and other new or previous colleagues. During the decades, our services and software have developed in phase with acquisition technology to become an indispensable component of both exploration and production, anywhere in the world.
