Abstract
An advanced geoelectrical technique for imaging potential fractures has been developed by Engineering Geophysics Laboratory in Kyushu University. The method, Fluid Flow Tomography (FFT), has been applied to monitor fluid flow behaviors during water injection and steam production operations in geothermal areas in Japan. Distribution and extension of potential fractures can be evaluated by 3-D inversion of the mise-a-la-masse data using a steel casing pipe as a charged current electrode in a surveyed area. It is concluded that potential fractures in geothermal reservoirs could be traced and visualized as a function of time by the charged potential method.
