Claim One:
1. A computer-implemented method for constructing an earth model using multi-offset-multi-attribute image volumes and identified geobodies associated with a geologic volume of interest, the method being performed by one or more processors configured to execute computer program instructions, the method comprising: updating a model to obtain an updated model, the updated model comprising one or both of an updated earth model or an updated velocity model, wherein one or more rock properties of geobodies represented in the updated model have been constrained based on assigned geobody types of identified geobodies represented in the updated model, and wherein the one or more constrained rock properties comprise one or more of velocity, anisotropy, density, acoustic properties, elastic properties, or petrophysical properties; obtaining synthetic seismic data corresponding to the updated model; obtaining a plurality of multi-offset-multi-attribute image volumes from the synthetic seismic data, wherein a given one of the multi-offset-multi-attribute image volumes (1) corresponds to one of an offset stack, an angle stack, or an azimuth stack of the synthetic seismic data, (2) is associated with a seismic attribute, and (3) includes geobody representations of geobodies previously unidentified in the updated model; performing a constrained seismic inversion to determine rock properties of the identified geobodies, and to identify other geobodies with associated rock properties in order to reduce differences between observed seismic data and the synthetic data, wherein the constrained seismic inversion is stabilized by the constrained rock properties of the identified geobodies; and obtaining a three-dimensional model based on the constrained seismic inversion, the three-dimensional model comprising one or both of a three-dimensional earth model or a three-dimensional velocity model.
