Abstract: A methodology for estimating stresses in the subsurface for the generation of a three dimensional (3D) mechanical earth model is provided. The method is executed via a processor of a computing system. The method includes generating a synthetic principal horizontal stress profile representative of a one-dimensional mechanical earth model (1D MEM) based on simplification that all formations are elastically isotropic. The method also includes combining the isotropically generated synthetic principal horizontal stress profile with an additional data-driven functional relationship for anisotropic formations to generate a global predictive conditional relationship based on a lithology dependent cutoff. The method also further includes generating a three-dimensional volume-based mechanical earth model using the global predictive conditional relationship.
