Abstract
The permeability of reservoir rocks changes continuously during their productive like due to, among other things, the coupled hydromechanical behavior of natural pre-existing and newly formed fractures. In this lecture, two types of numerical models build to study these phenomena will be presented. The first one is a multiscale approach developed to capture the coupled dynamic behavior of natural networks of subseismic fractures, which are too small to be all explicitly represented in the numerical model. The second type of model is an ongoing research on the particle clogging and fracturing in the near-well regions of unconsolidated sandstones. It aims a computational representation of the formation of fracture-like shear bands and the coupling of this strain localization with the mass transport of particles injected during the secondary recovery.
