Modelling of Conductive Faults with a Multiscale Approach

Abstract: Résumé -Modélisation des failles conductrices. Approche multiéchelle -La plupart des gisements pétroliers sont traversés par des fractures de multiples échelles. Parmi celles-ci, les failles conductrices peuvent avoir un rôle majeur sur les performances de production. Leur modélisation est problématique sur deux points : -la nécessité d'une représentation explicite des failles avec des dimensions de maille faibles ; -la modélisation des échanges polyphasiques entre le milieu faille et le milieu encaissant.

“…An explicit representation of those faults is necessary to properly match the multiphase field flow behaviour, that often involves early breakthroughs at given well locations. As a discrete representation of each individual fault is computer-intensive, a specific "conductive fault model" (Henn et al, 2004) may be adopted. The segregated flow concept that underlies that model avoids any vertical gridding of conductive faults and the related numerical constraints.…”

“…To overcome the drawbacks of the methods described above, Henn et al (2004) developed a specific model of conductive faults that ensures a precise and flexible description of fault geometry and fluid displacements, while keeping a high numerical performance. This model is based on an explicit representation of conductive faults and on the assumption of fluid gravity segregation within the faults, with negligible effects of capillarity.…”

“…The horizontal flow of segregated phases along fault planes is formulated with generalized Darcy's law using relative permeability and capillary pressure pseudo-functions. Calculation of these pseudo functions is detailed in Henn et al (2004).…”
