C06 Flexible upscaling using perturbed boundary conditions L.RICARD M. LE RAVALEC-DUPIN Y. GUÉGUEN Abstract 1 This paper presents a new technique for upscaling absolute permeabilities on coarse CPG grids. Within this framework traditional upscaling methods depend on arbitrary local boundary conditions. They are fairly accurate for lognormal fields but they fail for channelized fields and highly heterogeneous systems. The method introduced in this paper takes advantage of global fluid flow simulations to select pertinent local boundary conditions. These ones are then used for upscaling permeabilities. To reduce interpolation errors and to be independent from fluid flow numerical simulation schemes we
