The article presents the results of microseismic mapping of Chaykinskaya area using standard seismic gathers. Offsets more than 2 km and time interval from 3.5 s and, i.e. after the registration of primary artificial waves are used. Increasing of microseisms intensity (0-30 Hz) compared to intervals before first brakes was revealed. The anomaly of microseismic noise at the elevation in the northeastern part of the area confirmed by an inheritance of the anomaly on two parallel profiles and a profile crossing them was identified. This anomaly correlates in the area with a trap detected by the aero-gamma-spectrometry method. The investigation results of the microseismic emission can be used in an integrated interpretation of geophysical data in oil and gas exploration.

Keywords: seismic exploration, microseismic spectrum, oil and gas exploration.
