As has been known for some time, velocities of elastic waves propagating in most subsurface formations exhibit directional dependence, or seismic anisotropy. On their way to …
ERT and SP investigations were conducted in carbonate rocks of the Dinant Synclinorium (Walloon Region of Belgium) to find suitable locations for new water wells in zones with little …

Previous geological studies in the Basin and Range of the Western US have shown that conventional geothermal systems are usually located in geological settings of intense …
The existing fracture-characterization techniques are based on assuming the unfractured host rock either to be isotropic or the magnitudes of both the background and crack-induced …
