Paper Number: SPE-203908-MS
... acute triangulations, while satisfying quite general geometric constraints. For well aligned grids control points are constrained to the well trajectory and protection circles are used, whereas for boundary aligned grids halo construction is performed. Unstructured Delaunay triangulations (DT) have...

... classified into two categories: the advancing front method; and Delaunay triangulation ( Löner, and Parikh, 1988 ; Marcum and Weatherill, 1995 ; Mavriplis, 1995 ). The advancing front method provides an optimal point placement strategy and generates quality meshes. The advancing front method constructs...

... reservoir properties. We present recently developed techniques for adaptively constrained 2.5D Voronoi grid generation and for generic global flow-based scale-up. Our novel gridding approach is based on a new constrained Delaunay triangulation algorithm and a rigorous procedure of constructing a Voronoi...

... and is essential for the result of the simulation. A new approach for the simulation of faulted hydrocarbon reservoirs is proposed. The described algorithm iteratively generates a constrained Voronoi grid suitable for two-point flux approximation schemes. The algorithm is based on a Delaunay triangulation...
