| ¡@¡@This talk will address some new developments of scanning, gridding, discretizing, and visualizing technologies in numerical reservoir simulation. The scanning technology scans and extracts various geometrical data such as depth, thickness, porosity, permeability, and the location of wells, fractures, and faults. From scanning, the gridding technology generates corresponding 2D or 3D unstructured meshes. New discretization methods over these meshes have been developed. These methods are based on control volume finite elements and are capable to handle faults, horizontal wells, and unstructured meshes. The visualizing technology possesses real-time calculation and real-time display capabilities and provides streamline computations. As model examples in reservoirs, black-oil and compositional flow models will bediscussed. |
