RECEIVER ORIENTATION AND EVENT BACK-AZIMUTH ESTIMATION FOR DOWNHOLE MICROSEISMIC MONITORING USING A PROBABILISTIC METHOD BASED ON P-WAVE POLARIZATION

Microseismic event back-azimuth is an indispensable parameter for source localization in downhole microseismic monitoring, and the accurate orientation of horizontal components of downhole seismic receivers is vital for reliably determining the event back-azimuth.Variation in the monitoring data quality may jeopardize the accuracy of receiver orien

A number of evolutionary algorithms such as genetic algorithms, simulated annealing, particle swarm optimization, etc., have been used by researchers in order to optimize different manufacturing processes.In many cases these algorithms are either incapable of read more reaching global minimum or the time and computational effort (function evaluatio
