IDENTIFICATION OF PREVAILING ORIENTATIONS OF CRACKS Russian patent published in 2016 - IPC G01V1/28 G06F17/50 G06F19/00 E21B43/26 

Abstract RU 2594373 C1

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics and can be used for identification of properties of fractures in underground area. According to certain aspects orientation of main plane is determined for each of plurality of basic planes. Basic planes are determined with help of coplanar subsets of microseismic events when performing operations of hydraulic fracturing of underground zone. Quantitative parameter of orientations of basic planes in each of plurality of bands is calculated. In some embodiments, histogram is displayed for displaying quantitative parameter orientations of basic planes in each of ranges of orientations. Prevailing orientation of fracture is identified for underground zone on basis of one or more identified quantitative parameters.

EFFECT: technical result is improved accuracy of obtained data.
