“…These parameters were close to those given in literature ðm ¼ n ¼ 2Þ (Saner, Al-Harthi, & Htay, 1996). The comparison between different experimental data sets F -F and some predicted models allows us to conclude that the Shell model (for carbonate rock) gives the best fit (Sen, Kenyon, Takezaki, & Petricola, 1997).…”

“…In this case, a determination of the effective physical properties of porous material requires applying the selfconsistent effective medium methods that take into account the interaction of inhomogeneities. The theory and application of these methods for the prediction of elastic and electromagnetic parameters of porous media were considered by O' Connell and Budiansky (1974), Berryman (1980Berryman ( , 1992, Mendelson and Cohen (1982), Sen et al (1981Sen et al ( , 1997, Norris et al (1985), Shwartz (1994), Chinh (2000), and Friedman and Robinson (2002). The joint calculation of acoustic and electrical properties of terrigenous formations from the unified model was presented by Sheng (1991).…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractA technique for the primary and secondary porosity estimation is proposed. This technique is based on a resistivity model of carbonate formations with double porosity and the analysis of numerous core data. The resistivity model consists of an isotropic conductive matrix with a primary porous system and inclusions, which represent secondary porosity (vugs and fractures). Fracture systems are described by oblate ellipsoids of different sizes (which have the same orientation and aspect ratio) or by thin plates. These rock structures are characterized by an anisotropy of electrical properties. The components of the resistivity tensor have a nonlinear relationship with the matrix porosity and parameters of fracture systems (orientation and porosity). The model with spherical inclusions (Maxwell-Garnett approach) is applied to obtain the resistivity of vugular formations. The fluid type, saturation of matrix and secondary pores influence significantly the formation resistivity and anisotropy coefficient. When both pore systems are completely saturated by the same conductive fluid (the case of core analysis), the effective formation factor depends only on the matrix formation factor and the secondary porosity value. The statistical analysis of core data has shown that Archie's equation with cementation exponent m=2, is the best approximation to describe the matrix formation factor for carbonate formations in Mexico. For verification of the porosity separation technique, the fracture and vuggy porosities have been estimated for core with detailed description of pore structure.
