The article presents the results of microseisms mapping in the Paiyakhskoe oil field using seismograms of standard seismic survey. Calculations on different data sets give a stable picture of the distribution of microseismic activity over the area. The observed anomalous zones of frequency predominance in the range for 40 to 160 Hz are close to the AVO attribute distribution map; the two anomalous zones that the authors observed correspond to the well-known HC traps. The developed technology for the analysis of microseismic noise can be used in the search for lithological oil deposits as complementary. It can also verify other methods based on the use of seismic attributes.

Keywords: seismic exploration, microseism spectrum, forecast of oil and gas pools.
