摘要： A method and system are described for creating a subsurface model. The method and system may include updating a subsurface model having objects associated with a subsurface region. The method includes obtaining a subsurface model having a mesh formed from various nodes and forming blocks or mesh elements, which have mesh shapes. Then, areas of the mesh that need repair are identified and one or more of a local re-meshing operation, an edge-flipping operation, a collapsing operation and any combination thereof are applied to the identified areas. The resulting updated subsurface model is then outputted.

摘要： A method and system are described for creating a subsurface model. The method involves forming a volumetric representation having objects associated with the subsurface region; computing a value for each of the blocks based on an object priority function; and removing one or more blocks based on constraints and the object priority function to create the watertight model. Then, using the watertight model to perform simulations and in performing hydrocarbon operations.
