Abstract: A method may include determining various migrated azimuthal dip-angle gathers based on a migration function and seismic data from a seismic survey regarding a geological region of interest. The method may further include determining various partial dip-angle images using the migrated azimuthal dip-angle gathers. The method may further include determining various azimuthal bins that include the partial dip-angle images. The method may further include determining various wavefield components using an independent component analysis (ICA) function and the partial dip-angle images among the azimuthal bins. The method may further include determining a geological feature within the geological region of interest using the wavefield components.

Abstract: A method for determining a thermal maturity image of a subterranean region and a non-transitory computer readable medium, storing instructions for executing the method, are disclosed. The method includes, obtaining a seismic dataset for the subterranean region of interest, obtaining a thermal maturity value for a plurality of core samples taken from different positions within the subterranean region, and obtaining a plurality of well log types from the core sampling location. The method further includes determining a calibrated rock physics model based on the plurality of well log types, determining a pore fluid type based on the calibrated rock physics model, and determining a thermal maturity model based on the plurality of core samples, on the pore fluid type, and on the plurality of well logs. The method still further includes determining the thermal maturity image of the subterranean region based on the seismic dataset and thermal maturity model.

Abstract: A rock modeling method is disclosed. An effective rock property of a rock sample is determined based on a digital rock. Instead of upscaling rock properties, the digital rock is constructed by upscaling relationships and rock physics models of segmented rock materials. Relationships between different scalar, elastic, and petrophysical properties of different segmented rock materials are established at the high-resolution scale where the pore structure is resolved. These relationships are then applied to the same rock material at the macro-scale. Finally, the effective rock properties are computed using Darcy-like solver to get the final values at a representative rock volume. Embodiments allow for performing non-destructive fluid/solid substitution and other reproducible digital experiments to study control factors that affect these relationships within rocks.
