SYSTEM AND METHOD FOR EDITING GEOLOGICAL MODELS BY SWITCHING BETWEEN VOLUME-BASED MODELS AND SURFACE-BASED STRUCTURAL MODELS AUGMENTED WITH STRATIGRAPHIC FIBER BUNDLES

A method for editing a volume-based model imaging geological structures. An initial volume-based model comprising a volumetric mesh and updated geological data defined within a region of the model is received. The volume-based model is decomposed by converting the volumetric mesh into surface meshes linked by stratigraphic fibers to generate a surface-based model. The defined region of the surface-based model is edited by editing positions of control nodes of the surface meshes along the stratigraphic fibers in the defined region of the model so as to fit the updated geological data. The plurality of stratigraphic fibers are updated based on the edited positions of the control nodes so as to fit the updated geological data. The edited surface-based model is meshed to generate an updated volume-based model comprising a volumetric mesh defined by the edited positions of the control nodes. The updated volume-based model is stored and/or displayed.
