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 orientation which will further affect the... https://mylittlewardrobers.shop/product-category/shoes/
