The algorithm for elimination of data redundancy in hydraulic fracturing monitoring systems

Abstract

The important stage in the monitoring of hydraulic fracturing is construction of a graphical model of a fractured area. However, real data recorded in the process of hydraulic fracturing are characterized by a high intensity of seismic activity in the monitoring area, which makes it difficult to correctly construct such a model. The original algorithm is described, which allows one to eliminate the redundancy of miscroseismic sources and to highlight the local hypocenters of microearthquakes. The results obtained were used to construct a three-dimensional graphical model of a fracture.
