Abstract

This paper presents effects of gas- and water saturation on elastic parameters of rocks. Gas present in the pore space of rocks significantly decreases velocity of P-wave propagation whereas it is much smaller on S-wave velocity. Hence, a small VP/VS ratio can be an indicator of gaseous hydrocarbons in the deposit. The analysis was based on theoretical relationships for porous media, known as the Biot-Gassmann’s and Kuster and Toksöz’s models, and on well-logging data and results of the quantitative interpretation of wells logs. 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.
