.... Local stress fields around the fractures will change during reservoir depletion due to the fluid flow and deformation induced by fractures mechanical interference. The stress rotation is controlled by the magnitude of anisotropic stress, which is dependent on several reservoir and material properties...

By designing an inverse problem, we present a workflow to assess whether it is possible to estimate reservoir properties based on sparse measured data in off shore hydrocarbon reservoirs. To this purpose, a multi-layered reservoir model from the Dan field with various material properties...

... approach is here enhanced by introducing a softening rule to simulate the post-peak behaviour of rocks in the brittle regime. For this purpose, the degradation of the material properties has been expressed as a function of an internal variable (i.e., the cumulated value of deviatoric plastic strains) which...
