Abstract
The attenuation and velocities of compressional and shear waves are important parameters for predicting the nature of porous rocks. Intrinsic attenuation gives us information on the nature of the pore fluid, whilst seismic velocities teIl us about the rock matrix. Surprisingly, little is known of the relationships between the seismic attenuation of sedimentary rocks and their petrophysical and geotechnical properties such as porosity, permeability and clay content. Part of the work of the Geophysics Research Group at P.R.I.S. is to study these relationships by making small scale laboratory measurements under simulated reservoir pressures.
