Abstract

Surface representation of complex structures is one of the important subjects in both geological modeling and computer graphics. Computer graphics has been involved in these issues and gradually developed a wide range of useful techniques to deal with models consisting of complex topology, e.g. grid-free surface-based modelling approach. Although geologists have been using these approaches in there work (e.g Non-Uniform Rational B-Splines (NURBS)), there are still other different surface-based modeling methods that are widely developed by computer graphics but have not yet been extensively investigated and tested in geological and reservoir modelling. One example is relatively recent developments in the field of subdivision surfaces. We investigated the use of subdivision surfaces for 3D complex geological and reservoir modelling, as one of the major parametric surfaced-based modelling methods. Also, the advantages and weaknesses of subdivision surfaces and NURBS in geological modelling are compared. Subdivision surface is the standard technique in the gaming and animation industry and generates smooth, grid-free and controllable meshes by a recursive algorithmic approach. However, unlike the NURBS, the subdivision surfaces method has received relatively little attention so far in geological and reservoir modelling. The subdivision surfaces method has the advantages of supporting arbitrary topology and watertight modeling, which are suitable for 3D geological and reservoir modelling. Also, we investigated approaches to make the subdivision surfaces method compatible with the non-manifold topology, making it attractive for modelling the structures with complex topology. Taking the differences and similarities of various surface-based modelling methods into consideration can lead to achieving high-quality and practical representation with few difficulties in complex structural geomodeling.
