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 18):
The computer readable storage medium of  claim 14  wherein, to establish said matrix-fracture connections, said instructions further comprise:\n determining geographical intersecting faces between cells of said matrix mesh and cells of said fracture mesh; \n for each intersecting face, calculating a matrix transmissibility value at the face of said matrix mesh, calculating a fracture transmissibility value at the face of said fracture mesh, and calculating a transmissibility across the face between said matrix mesh and said fracture mesh as a harmonic average of said matrix and fracture transmissibility values; \n calculating the matrix transmissibility value using a two-point flux approximation; and \n calculating the fracture transmissibility value using a two-point flux approximation, \n wherein generating a volumetric fracture mesh includes extruding an original face of each cell within a surface fracture mesh by a corresponding aperture width, and establishing matrix-fracture connections further comprises, for each face, calculating the fracture and matrix transmissibility values as functions of the intersection of the corresponding original face of the surface fracture mesh with the face of the matrix mesh.
