Abstract/Summary With the advanced field observation, image and drilling technology, geological structure of reservoirs can be described in more details. A novel 3D mesh generation method for geological reservoir models is proposed and implemented with arbitrary stratigraphical surface constraints , which ensures the detailed geological structure and material properties are well described and analysed. Specifically, the stratigraphic interfaces are firstly extracted and meshed, and then the tetrahedron mesh is generated with the constraints of the meshed surfaces. The proposed approach includes the following five steps: (1) extracting stratum interfaces; (2) creating a background mesh with size field on the interfaces; (3) constructing geodesic isolines from the interface boundaries to the interior; (4) employing a geodesicbased approach to create triangles on the area between adjacent isolines and to combine them together; (5) generating tetrahedron mesh for 3D reservoirs with constraints of the above surface triangular mesh. Th is approach has been implemented and applied to the Lawn Hill reservoir model to demonstrate its effectiveness and usefulness.
