Abstract

Summary

We layout the workflow to build a stress induced orthorhombic model using the excess fracture compliance rock model. In comparison to the third-order elasticity method previously used, this workflow has the advantage to possess no constraints on the background material symmetry and principal stress directions. We also demonstrate how this workflow will be of key use on a Gulf of Mexico (GOM) case study by showing the strong correlation between the observed azimuthal anisotropy from data and the principal stress direction.
