The Acoustic Properties of Carbonates at Sonic and Ultrasonic Frequencies

P037 THE ACOUSTIC PROPERTIES OF CARBONATES AT SONIC AND ULTRASONIC FREQUENCIES J.SOTHCOTT 1 S.ASSEFA 1 C.M C CANN 1 and S.E. JOHNSTAD 2 Summary This abstract describes a set of acoustic velocity and attenuation measurements on two fully brine saturated carbonates at low and high frequencies. The data demonstrate that at reservoir pressures the compressional wave and shear wave quality factors increase (attenuation decreases) with decreasing frequency and that the velocity dispersions are significantly smaller than those of reservoir sandstones. Aim 1 The aim of this work is to investigate the effect of frequency scaling on the acoustic properties of
