Abstract: A method for geomechanical and rock physics modeling of a geologic volume of interest may include solving for the elastostatic boundary value problems using a finite-difference method which applies the Virial Theorem.

Abstract: A method is described that includes accessing, for a geological medium: a horizon model including a plurality of horizons in the geological medium; a fault model including a plurality of faults in the geological medium; and a rock property model including one or more physical rock properties at a plurality of spatial locations on a first grid corresponding to the geological medium. The method further includes determining intersections between the horizons and the faults by correlating the horizon model with the fault model and calculating a faulted structural model for the geological medium in accordance with the intersections between the horizons and the faults. The method further includes generating an earth model for seismic forward modeling by assigning one or more physical rock properties to the faulted structural model in accordance with the rock property model.

Abstract: Stratigraphy is inferred over a volume of seismic information. Seismic images are implemented to create higher fidelity stratigraphic structure by leveraging a process that translates seismic image information back and forth into and out of a space that is flattened on geographic time. The stratigraphic structure inferred may be implemented in seismic modeling.

Abstract: A system and model for estimating rock properties may include receiving an initial reservoir model of the subsurface, calculating p-dependent reflection coefficients and vertical travel times at each boundary in the initial reservoir model, performing a Discrete Fourier Transform using the reflection coefficients and travel times to get a temporal spectrum of the reflectivity trace, multiplying by the temporal spectrum of a desired wavelet, performing an inverse DFT, and extracting the amplitude values at the vertical travel times for each boundary to generate synthetic seismic data. This synthetic seismic data may be compared with recorded seismic data to update the reservoir model.

Abstract: Strength parameters of the contents of subsurface caverns are deduced through seismic information. Known properties of formations surrounding the caverns, and ratios of seismic amplitudes between the caverns and the surrounding formations are leveraged to deduce the strength parameters within the caverns.

Abstract: Full wavefield images are produced for a target within a geologic volume of interest from which seismic information has been acquired. The images are generated by generating Green's functions for wavefields propagating from a location at or near the target to the surface without requiring imaging of the entire geologic volume of interest.
