Abstract:
The disclosed embodiments include a method, apparatus, and computer program product for generating multiple correlated meshes around complex and discrete fractures for the purpose of reservoir simulation. In an initial two-stage process, a 2.5-dimensional mesher algorithm, may be used in conjunction with an extended anisotropic geometry-adaptive refinement algorithm to produce, from a structured grid Earth Model, a refined reservoir model. Fractures may be modeled as a volumetric mesh that is independent of the refined reservoir model. Thereafter, the two independent, overlapping meshes are combined by forming matrix-matrix, fracture-fracture, and matrix-fracture connections to form a single model to allow rapid simulation of an extremely complex fracture network with sufficiently accurate results.

Claim (Index 10):
The method of  claim 1  wherein said generating said volumetric matrix mesh further comprises:\n receiving a reservoir specification; \n identifying, based on the reservoir specification, a set of fractures including 2.5-dimensional-permitting fractures and other fractures; \n generating an unstructured reservoir model including an extrusion mesh which models the 2.5-dimensional-permitting fractures in three-dimensions; \n anisotropically refining one or more cells in the unstructured reservoir model corresponding to the other fractures, by:\n identifying a direction within the three dimensions in which the cells should be refined; and \n splitting an edge of the cells, the edge being in the direction within the three dimensions; \n \n resolving a fracture network within the unstructured reservoir model using the refined cells; and \n generating a refined reservoir model using the fracture network.
