Abstract

We have applied our approach for microseismic imaging to the data obtained from the German Continental Deep Drilling program (KTB project). This is a continuous data stream containing induced microseismicity data recorded at a single 3C geophone located at approximately 3.5 km depth. Using P and S time picks we have located 58 microseismic events using data from the borehole geophone and from near‐surface stations. Since microearthquakes occur not at the same time, we have managed to separate continuous data stream recorded at the receiver to the number of 3C traces containing waveforms from different events. Using these traces we have produced seismic gather for the micro seismicity cloud. We apply our approach to the produced seismic gather and construct 3D images of the seismic data between P‐ and S‐ direct waves. There are two focused reflectors revealed within the micro seismicity cloud which belong to SE2 reflector. In order to check consistency of the obtained results, we compare our results with seismic attributes obtained from the surface seismic 3D depth migrated image. Obtained result is consistent with seismic attributes by the location and dip, furthermore it provides with more detailed image of the fault zone fine structure.
