heal.abstract	The permeability reduction around a perforation cavity is analyzed as the result of grain crushing due to the perforation process. The poroelastic solution of a plane wave emanating from a cylindrical cavity is used to derive expressions for the intergranular stresses responsible for grain-crushing phenomena. These phenomena are examined on the basis of Hertzian contact theory of fracture and micromechanical descriptions of granular assemblies assisted by discrete element simulations. Results are presented for hydrostatic loading conditions for comparison with existing experimental results, and for uniaxial strain conditions as an approximation to the stress field around the perforation. The analysis can be applied to the prediction of the extent of the permeability-reduced zone and used for estimating the permeability reduction around the perforation. © 1993.	en
