Keywords:Electrical resistivity, Elastic-wave velocity, Porosity, Granite

Elastic wave velocity is sensitive to the density and shape of cracks, while electrical resistivity is sensitive to the porosity and its connectivity. We are currently developing a system for simultaneous measurement of elastic wave velocity, resistivity and porosity using the intra-vessel fluid flow apparatus. In this presentation, we will introduce the systems and preliminary results of the simulateneous measurement for granite.
