Abstract

An example of defining a hydraulically created cracks with a cross-borehole mise-à-la-masse method is presented. Potential anomaly was clearly measured after the hydraulic fracturing at Higashi Hachimantai geothermal field. This anomaly is caused by the created artificial crack filled with the conducting fluid used for the hydraulic fracturing. Two numerical methods, namely, the axially symmetrical 2-D finite element method (FEM) and the 3-D volume integral equation approach were used for an interpretation of the measured data of the excited potential. Effects of the conductivity inhomogeneity of the host rocks was discussed by the numerical results given by the 2-D FEM. The size and the orientation of the created crack was expected by the 3-D volume integral equation approach.
