Principles and Rules for Effective 3D Volumetric Restoration with Kine3D-3

Abstract

The Gocad plugin Kine3D-3 has been developed to perform volumetric restoration on meshed 3D volumes. The presentation will focus on the principles of restoration and on the rules to follow so that the restoration adds value for the data and helps for further interpretation. In order to restore a folded and faulted geological unit, the technique implemented within Gocad consists in solving a mechanical problem. The restored geometry is assumed to have the minimum internal deformation, given the rheology of its layers and given some geometrical constraints. The constraints will be explained and their geological translation will be highlighted. However, as for any minimum solution, overconstrained or underconstrained problems are to be avoided, because no solution might be reached.. Rules to avoid such situations will be illustrated on practical geological configurations Restoration may be used to evaluate the deformation of faulted and folded reservoir horizons. Some examples will show the sensitivity of results to the geometrical constraints. Restoration may also be used to perform quality control on an interpretation and to correct the interpretation. The specific problem of fault interpretation and quality control will be treated with didactic examples.
