Calculating accurate Shmin profiles is critical for understanding fracture geometries and depletion patterns. This presentation serves as both a practical guide and a conceptual overview, walking you through the technical workflow of using the ResFrac Properties vs. Depth Wizard to import log data and estimate stress profiles. 

Beyond the software tutorial, the presentation reviews the primary methodologies used across the industry to compute Shmin. It breaks down the theory and limitations of traditional Eaton and Extended Eaton models—which rely on elastic assumptions—and contrasts them with the newer Viscoelastic Stress Relaxation (VSR) methods. The guide also explains how the frictional faulting limit can be utilized to establish a reliable lower bound for stress profiles.
