Abstract

Ultrasonic P and S wave travel-time measurements have made on Cretaceous sandstones from the Locahaline silica mine in West Scotland whilst being subjected to increasing pressure in a Hoek cell, The resulting dryframe P and S wave vebcities for a sequence of pressure values between 0 and 70MPa are then transformed into elastic modeli using density calculated from pore volume squeeze-out on a sister sample. Both the exces normal and the tangential compliance are calculated by using differential effective medium theory to compensate for host matrix softening due to evolution of the equant porosity.
