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...
An original information technology for monitoring of hydraulic fracturing is proposed and implemented. This technology is based on detection of sources of microseismic oscillations, data processing and visualization of three-dimensional dynamic model of fractal fractured zone.
This paper provides description of the algorithm of statistical detection, which was adapted for seismic pulses occurring in grid nodes of the location during hydraulic fracturing. The algorithm provides high quality detection of seismic signals with random initial phase of seismic pulse, occurring when rock of productive reservoir is being broken.
This paper describes comparison of statistical and quadrature correlation algorithms, which were adapted for seismic pulses, occurring in grid nodes of location during hydraulic fracturing monitoring.
The algorithm of correlation detection of seismic pulses in grid nodes, which are located by the original method of hydraulic fracturing monitoring, is explored and applied in this work. The algorithm provides high quality of detection with a random initial phase of a seismic pulse.
