Abstract: Hydraulic fracturing microseismic monitoring techniques are compared: side view seismic location and vector scanning. Operations were performed in Russia and China. The techniques of field acquisition and data processing are compared. The recommendations are discussed in respect of further improvement of both methods, imaging resolution increase and utilization of all available a priori geologic information for better operations planning, acquisition and data processing. As one of the main conclusions, it is proposed to further improve microseismic monitoring based not on detection of chaotic separate point events, but on detection of characteristic entire wavefronts (signatures) of the typical hydraulic fracturing objects: primary horizontal and vertical fractures, secondary fracture planes. The object-oriented approach allows us to significantly reduce imaging calculation time. Separately, the point is discussed that hydraulic fracturing microseismic monitoring in both cases, West Siberia and China, has significantly enriched geological and geophysical knowledge and contributed to optimization of project solutions regarding deposit development and operation.
