Abstract
A subsurface representation of a subsurface region is generated section by section from the base section to the top section. Seismic characteristics in a section of the subsurface representation are simulated, and the simulated seismic characteristics are compared with seismic characteristics in a corresponding section of the subsurface region to validate the section of the subsurface representation. Once a section of the subsurface representation is validated, the next/overlying section of the subsurface representation is generated. The underlying section provides one or more boundary conditions to constrain generation of the overlying section.
