Physics of fluid-induced seismicity — •Serge Shapiro — FR-Geophysik, FU-Berlin, Malteserstr. 74-100, Hs.D, 12249, Berlin

Injections of borehole fluids into surrounding rocks are often used for developments of hydrocarbon or geothermal reservoirs. Microseismicity occurring during such fluid-related operations has a large potential in understanding of physics of the seismogenic process as well as in obtaining detailed information about reservoirs at locations as far as several kilometers from boreholes. Here we summarize a concept for interpretation of microseismic data which provides a possibility to infer an information about hydraulic properties of rocks. Estimates of hydraulic diffusivity tensors on large spatial scales as well as imaging of its distributions in space resulting from this concept can be of significant importance for industrial applications and understanding of physical properties of geological structures.
