We present the problem of determining crack density, porosity and permeability of cracked-porous carbonate reservoirs by examining the origin of anisotropy considered from a physical model of porous reservoir rock with a system of vertical fluid-filled cracks. This stabilizes the non-linear optimization inversion procedure and determines a set of significant reservoir parameters on a basis of qP, qS1 and qS2 velocities measured in a VSP experiment.
