Hydraulic Fracture Orientation and Stress Field Revealed by Surface Based Microseismic Monitoring

Abstract

Abstract-Surface based micro-seismic monitoring of well stimulation by hydraulic fracture now has been accepted by domestic oil and gas industry. Micro-seismic data can be used to evaluate the stimulation result, predict reservoir stress state and guide the drilling of horizontal laterals, etc. Surface based microseismic monitoring methods and the corresponding data processing technique naming vector scanning of micro-fracture has successfully mapped the hydraulic fractures. Through analysis of the spatial and temporal distribution of fracture energy, the hydraulic fracture process is understood. The current stress state of the stimulated reservoir is then determined by integrating the available geologic information and interpreted micro-seismic data.
