    摘要： 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. The system uses different geologic data from seismic interpretation, well bore readings, and field observation to provide numerous results, such as predicted fracture propagation based on perturbed stress field.

    摘要： Systems for modeling and building models of oil and gas deposits. In particular, the utility model relates to systems designed for automated identification of surfaces for building a geologic-hydrodynamic model of an oil and gas deposit based on seismic data. A technical result is the improvement of the accuracy in building a geological-hydrodynamic model of an oil-and-gas deposit. The objective of this utility model is to provide a system designed for building a geological-hydrodynamic model, in particular, automated (that is, requiring the user to participate only in the stage of initial data input) construction of a set of surfaces based on input seismic data. The output surfaces can be used, without additional processing, to construct a geological-hydrodynamic grid. The input data for the system are volumes of seismic data attributes P, Q; and seismic volume (optional).
