Summary 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.
