Future advancements in subsurface characterization will require a superior integration of the multi- physics problems through modern artificial intelligence techniques and advanced statistical methods than the existing methods. From the geophysical end, isotropic and anisotropic visco-elastic prestack seismic waveform inversion need to be integrated with advanced imaging tools such as the reverse-time migration to simultaneously estimate depth images and subsurface visco-elastic properties of the P- and S-wave velocities, density, and P- and S- wave attenuations and other anisotropic properties from three- dimensional seismic data volumes. Rock-physics models for estimating lithological and fluid properties (mineralogy, fluid saturation, porosity, permeability, in-situ stress field, etc.) from these visco-elastic models, well, and core data must be developed and incorporated into a rock-physics inversion scheme under a Bayesian framework to estimate lithological and fluid properties and the associated uncertainties. The visco-elastic models from selected locations must be used to train a machine- learning system, i.e., an artificial intelligence system, for predicting the visco-elastic models and the lithological and fluid properties directly from seismic data. Finally, combining these advanced geophysics/rock physics/machine-learning tools with the reservoir simulation tools into an integrated framework for predicting the dynamic properties of the subsurface fluids and stress-fields would enable developing the reservoir characterization of the next generation.
