FIELD: geophysics.
SUBSTANCE: invention relates to geophysics and can be used in analysis of microseismic data. Invention discloses system, method and software for analysis of microseismic data from operation of hydraulic fracturing. In some aspects planes of crack are identified based on microseismic events of operation of underground zone hydraulic fracturing. Each crack plane binds to subset of microseismic event data. Groups of confidence levels are identified from planes of cracks. Each group of confidence level includes fracture planes, having accuracy trusted value within corresponding range. Graphical representation of cracks planes is generated. Graphical representation includes separate diagram for each confidence level group.
EFFECT: technical result is increased accuracy and reliability of identification of fractures planes geometrical representation.
