FIELD: mining.
SUBSTANCE: group of inventions refers to a method, a system and its application for downhole monitoring of a formation hydraulic fracturing. Method includes the steps of: interrogating the optical fiber disposed along the borehole trajectory in order to form a distributed acoustic sensor; collecting data from multiple longitudinal sections of the fiber; and processing the said data to obtain a proppant washout indication.
EFFECT: technical result is providing the possibility in real time to control the process of the formation hydraulic fracturing.
