In order to model the effect of oil or gas production on the seismic response of a reservoir, it is necessary to know how two types of variable parameters impact the rock seismic properties. These are the state of stress of the reservoir and the nature of the saturating fluids.

Laboratory measurements of seismic P- and S-wave velocities and, secondarily, wave attenuation under various conditions of pressure and saturation (petroacoustics) are a great help in understanding the influence of thse parameters on the reservoir. This paper presents the methods used at the Rocks Physics Laboratory of the Institut Français du...
