Problems of borehole and surface microseismic hydrofrac monitoring

The microseismic monitoring is an innovative geophysical technology which normally employed to determine the geometrics of a fractured zone created by hydrofrac operations. In this note emphasis is made on both technological risks and success factors of the borehole and surface microseismic monitoring techniques based on the experience in the oil-gas condensate fields in Western Siberia as well as the optimal solution is proposed subject to problems to be solved using monitoring. The paper is based on the reportmade by the authors in XV «Gal’perin readings 2015» conference.
Materials and methods
Hydrofrac passive seismic monitoring with borehole and surface seismic observation, microseismic monitoring, adaptive source tomography.
Results
The experience of the application of both borehole and surface microseismic monitoring performed for quality control operations forfracturing oil and gas fields in Western Siberia is outlined.
Сonclusions
Microseismic technology allows estimating the quality of performed hydrofrac operation that helps to optimize the oilfield development.
