Abstract: A method can include receiving a geomechanical model associated with a geologic environment that includes a borehole where the geomechanical model includes a vertical dimension and lateral dimensions and where the borehole includes a lateral extent that spans a lateral distance in the geologic environment; conditioning the geomechanical model to provide a conditioned geomechanical model that includes representations of structural features based at least in part on borehole-wall image data of at least a portion of the lateral extent of the borehole; and determining a stress field for at least a portion of the geologic environment using the conditioned geomechanical model. The step of conditioning the geomechanical model can optionally include conditioning the geomechanical model to provide a conditioned geomechanical model that comprises representations of structural features based at least in part on sub-surface tool data of a substantially lateral extent of the geologic environment.
