Oct, 2014
Where was the Eriksfiord team on 23. OCT 2014? Hint: Under their feet are a strike-slipper, a subduction zone, a rift and two magma chambers.

Eriksfiord will present "Normal faults in the wellbore perspective, and geomechanical prediction of their instability modes" at The Geological Society London. Presented by Carsten Vahle

9th June, 2014
Orlen Upstream and Eriksfiord are coauthors of "Stress field and natural fracture systems in Polish Lower Paleozoic shale belt in Poland based on FMI studies." for the Shale Science conference at Copernicus Science Center in Warsaw. The paper will be presented by Birger Hansen

April 2nd, 2014, at 11:00,Solastranden Gård
Eriksfiord, Norway presenting in spring NFES meeting "Cooking cores with image logs - a case study from the Lower Jurassic Cook Formation (Kvitebjørn Field, NCS)" at NFES


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 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.
