Experimental Geophysics Group

The Experimental Geophysics Group carries out a unique blend of field- and laboratory-based geophysical studies, with particular focus on rock properties and how in situ conditions influence them.  The group carries out a wide range of ultrasonic measurements on materials and fluids subject to conditions of pressure and temperature. As the work is of a highly experimental nature, we are capable of working to design and fabricate ultrasonic apparatus to carry out feasibility investigations. The laboratory also has a range of tools for characterizing porous media. We also have the capability to measure the complex dielectric constants (permittivity) of solids and liquids from 10 MHz to 3 GHz. The group has also built up extensive field capabilities and conducted geophysical surveys on six continents and under conditions from both polar regions to the equator. Our field equipment includes a complete set for carrying out high resolution surface seismic surveys, including a 6000-lb truck-mounted seismic vibrator. The group is also able to conduct geophysical logging surveys to depths as great as 3000 m. Of particular note is a new state-of-the-art downhole digital seismic recording system that is able to work continuously at temperatures of 135 C. The group is very open to collaboration with industry on either a fee-for-service, contract, or grant, depending upon the situation.
