ACCURATE MODELLING OF MATRIX-FRACTURE TRANSFERS IN FRACTURED POROUS MEDIA THROUGH SUB-GRIDDED DUAL-POROSITY MODELS

CARINE FAMY, BERNARD BOURBIAUX, PATRICK LEMONNIER, MICHEL QUINTARD & CARINE FAMY
Conventional models to represent fractured media are often based on the “dual- porosity” concept (Warren and Root, 1963). In most simulators, to represent the exchange between the fracture and matrix media, we use an approximate pseudo-steady- state mass exchange formulation resulting from an upscaling of the matrix block- scale flow (Landereau et al., 2001). This formulation is reasonably predictive for single-phase flows, but generally inaccurate for multiphase flows. This is mainly due to the impact...
