Effects of Shale Content and Porosity on Elastic Parameters of Reservoir Rocks

The paper presents effects of shale content and porosity on elastic parameters of rocks. The analysis was based on theoretical relationships for porous media, known as the Biot-Gassmann’s and Kuster and Toksöz’s models, and on Raymer-Hunt-Gardner formulas. Well-logging data and results of the quantitative interpretation of well logs were also analysed. Data were acquired by the Geofizyka Krakow SA under the project no 6T12 2003 C/06006 realized in 2003 (Pietsch et al. 2003). The relationships between P-wave and S-wave velocities and reservoir parameters may contribute to solving some problems associated with seismic interpretation of wave forms in autochthonous Miocene deposits.
