Hydraulic fracturing experiments for making a man-made reservoir have been conducted on HDR project by CRIEPI since 1986. The Vertical Electric Profiling (VEP, hole-to-surface) method of the geotomography has been applied to monitor fluid-flow behaviors during massive hydraulic fracturing operations. Self potentials (streaming potentials) and charged potentials (apparent resistivities) were continuously observed at multiple stations on the ground surface before and during pumping operations for estimating fluid-flow front and fracture extents. The injected fluid-flow was continuously imaged as a function of time with a personal computer on the Hot Dry Rock site.
