Presentation by Eriksfiord at the SPWLA-Houston Chapter Spring topical Conference, see SPWLA-Houston
Eriksfiord is 15 years old this year, counting from the registration of Eriksfiord AS in 2001 in Norway. But really, our roots go back to 1983 when Birger Hansen
and Jean-Paul Richert founded the Dipmeter User Group as a forum for oil company specialists in log-based detection of geological structures. Now as then, our main
aim is the development of a science-based methodology and user-controlled software for describing and generalizing sedimentary and deformational structures on the
borehole wall, and provide independent advice to oil companies.

in the spotlight. Eriksfiord invited by Oracle to present at JavaOne meeting in San Francisco.
Where was the Eriksfiord team in OCT 2015? Hint: Peridotite, chromite, minarets, personal bunkers ....
Since commercial launch, our VINLAND software
has already seen important additional functionality, most notably
Image orientation can be North, High-Side or Arbitrary
Vuggy porosity calculator
Mogi-Coulomb and Stassi D Alia criterion for shear failure
Stress influence on fractured rock permeability
For stress influence on compressing or dilating a dominant fracture set, we use a reversible model taking into account shear and effective normal stress.
When a fracture is picked on the image, its stress state is instantly displayed.
For a given stress-tensor, spacing and aperture, contours in the stereogram above shows the fractured rock permeability relative to the unstressed state.
