- The research program is an experimental study of static and dynamic poroelastic behavior of rocks. Measurements of Skempton`s coefficient and undrained Poisson`s ratio together with drained bulk modulus and shear modulus will provide a complete set of the four poroelastic moduli. Stress coupling to fluid flow in fractured rock can occur also through changes of fracture permeability due to fracture compressibility. Numerical models that include this effect will be compared with standard double porosity models of fluid extraction from oil reservoirs. Wave velocity and attenuation measurements will be made from seismic to ultrasonic frequencies to establish a phenomenological model of the effects of permeability, porosity and saturation for seismic exploration of oil and gas and for seismic characterization of an aquifer for environmental restoration and waste remediation.
