Microseismic Sounding Technology Development for Engineering Applications

Description of the Micro seismic Sounding Technology developed by the authors for the investigation of the Earth crust deep structure (including oil & gas deposits) is presented. Developing technology allows effectively allocate the velocity in homogeneities and has significant informative and economic advantages under deep depth investigation in comparison with known seismic methods. The basic idea of the developed approach is the following: geological heterogeneity (for example, mineral deposits or underground reservoirs filled with oil, gas or fresh water), manifest themselves like the micro seismic wave field anomalies at the Earth´s surface. Developed technology is based on the allocation of anomalies in deep micro seismic wave field spectrum in the area of the probable geological heterogeneity (mineral deposits).
