Exploitation of self-consistency and differences between volume images and interpreted spatial/volumetric context

Abstract

Self-consistency and/or differences between volume images and interpreted spatial/volumetric context may be exploited for improving seismic imaging and estimation of attributes of geobodies, in accordance with one or more embodiments. Exemplary embodiments allow exploitation of positional and/or shape discrepancies and/or similarities of geobodies in image volumes associated with a geologic model of a geologic volume of interest to improve the accuracy of the geologic model and/or the image volumes. Constraints associated with the geologic volume of interest may be determined and/or utilized to confirm and/or specify dependencies between attributes that are potentially associated with individual geobodies.

Background technique [0004] Perform seismic imaging and subsurface interpretation to obtain as accurate a geological model of the Earth's subsurface volume as possible. Conventional industrial workflows typically include the following sequence of processing steps: (a) processing seismic data into a 3D seismic image volume of the Earth's subsurface volume; (b) extracting properties (e.g., velocity, Poisson's ratio, density, acoustic impedance, etc.) at each subsurface point in the Earth's subsurface volume; (c) int...
