Abstract: Systems and methods for predicting a stress attribute of a subsurface earth volume. One or more linearly independent far field stress models and one or more discontinuity pressure models may be simulated for the subsurface earth volume to generate stress values, strain values, displacement values, or a combination thereof for data points in the subsurface earth volume. A processor may be used to compute a superposition of the one or more linearly independent far field stress models and the one or more discontinuity pressure models. The stress attribute of the subsurface earth volume may be predicted, based on the computed stress values, strain values, displacement values, or the combination thereof.

Abstract: A method can include sampling points for at least a portion of a model of a geologic environment; generating a meshless model based at least in part on the points where the points correspond to nodes having respective domains of influence; and, based at least in part on the meshless model, computing a tensor field associated with forces experienced by at least a portion of the nodes. Various other apparatuses, systems, methods, etc., are also disclosed.

Abstract: Stress and fracture modeling using the principal of superposition is provided. A system simulates linearly independent far field stress models for a subsurface earth volume, computing stress, strain, and displacement values based on superposition of independent stress tensors. Based on the precomputed values, the system generates real-time recovery of paleostress values, or, stress, strain, and displacement parameters for any point in the subsurface volume as the user varies far field stress values. The system recovers one or more tectonic events, or a stress tensor represented by a ratio of principal magnitudes and associated orientation, using fault geometry, well bore data (fracture orientation and secondary fault plane data), GPS, InSAR, folded and faulted horizons, tiltmeters, slip and slikenlines on faults.
