f Direct and inverse problem estimating of reservoir structure

This report is a review of recent results obtained through the study of physical parameters carbonate reservoirs, which is presented by pore-cracked model under stress . As a basic model of cracked solid, we assume a linear elastic matrix with some system of distributed penny-shaped of ellipsoidal inclusions. The distribution function of inclusions with respect to orientation angle and aspect ratio is considered to be a function of applied stress. The latter predicts non-linear elastic behaviour of cracked solid and theoretically determines the dependence of effective elastic modules, heat and electrical conductivity on applied stress and fluid pressure .
