THE EVALUATION OF THE EFFECT OF FRACTURE GEOMETRY ON PERMEABILITY BASED ON LABORATORY STUDY AND NUMERICAL MODELLING

The geometry of fractures includes orientation, spacing, aperture are among the parameters affecting permeability in rocks. Studying the effect of fractures geometry on the permeability in a laboratory scale requires the selection of a suitable sample in terms of physical and mechanical properties....
