title = "Detetection of mechanical failure during hyraulic fracturing through passive seismic microseismic monitoring",
abstract = "Microseismic monitoring is extensively used for detection of microseismic events induced by hydraulic fracture stimulation and detected microseismic events are assumed to be caused by fracture growth in a formation. However. not ail microseismic e\ents arc created equal as some events might be caused by mechanical changes in the completion. Source mechanism analysis of the micro-earthquakes prosed to be an excellent tool to discriminate between the two types of events. We show a non-shear event of stage 4 that seems to be related to a mechanical failure on the casing, as the energy radiation pattern is mostly horizontal and sub parallel to the horizontal section of the well and consistent with tensile opening. Fracture related events are well explained by double couple dip-slip mechanisms occurred at time of fracture propagation while pumping.",
