The Discrete Analysis workflow

The goal of the Discrete Analysis workflow (MODEL > Fault Stability > Discrete Analysis) is to estimate the stability of the faults in the subsurface. It has been found that optimally oriented faults with high ratios of shear-to-normal stress are critically stressed and likely to be active in the current stress field. Faults with low ratios of shear-to-normal stress are less likely to be active. With the results at produced the end of the workflow, you can analyze the fault stability using output properties such as tau ratio, critical injection pressure and Coulomb failure function.

The required input information for the workflow includes pore pressure, orientation and magnitudes of the in-situ stresses. Together with the fault geometry, the fault stability can be calculated with the last step of the workflow.
