The results of field experimental work on microseismic sounding of the Bystryanskaya area of the Minusinskaya depression using autonomous receivers are presented. Field materials were processed, a deep section was built using the method of microseismic sounding. The resulting section was interpreted. The dependence of the method error on the record length number was studied. The procedure for calculating the dependence of this statistical error is described. For the first time, a modification of the automatic rejection of microseismic sounding data was tested. An algorithm has been developed and described that improves the quality of the processed data. Comparison of the results obtained by the old and new algorithms is carried out. The differences in the final sections are explained. Comparison and estimation of the distribution of the statistical error on the section by both algorithms is carried out. The prospect of the method for the search for gas deposits is estimated. A technique is proposed that significantly speeds up field work.
