WebNov 28, 2024 · Describing matrix–fracture interaction is one of the most important factors for modeling natural fractured reservoirs. A common approach for simulation of naturally fractured reservoirs is dual-porosity modeling where the degree of communication between the low-permeability medium (matrix) and high-permeability medium (fracture) is usually … Groundwater movement in naturally fractured and heterogeneous porous aquifers is highly complex, due to a strongly varying velocity field with multiscale correlation lengths. A key problem is how to describe tracer and contaminant movement in such systems. Realistic quantification of this … See more Groundwater movement in naturally fractured and heterogeneous porous aquifers is highly complex, due to strongly varying velocity … See more We mention here briefly the conceptual picture and mathematical language associated with the CTRW approach.
