We then tune key completion parameters using an in-house fracture propagation model to provide hydraulic fracture geometries that are constrained by the microseismic cloud. In the history matching process, we...

... times) with reasonable accuracy of predicting traveltimes on a fine imaging grid. Overall, the use of artificial neural networks results in a speed-up of the Kirchhoff migration operator in two applications: microseismic event localization (by three times) and reflection-seismic migration (by four times...

... by preventing waveforms of electrical or mechanical noise from being processed. In a production environment, the event processing workflow is run on distributed servers and analyzes triggered seismic data in real-time. Depending on the severity of the microseismic events detected, operators are immediately...

... these theories to a real microseismic dataset, two types of triggering front expansion patterns are evident. With the presence of a dominant hydraulic fracture, the radius of the triggering front expands linearly with time. Moreover, the microseismic event cloud forms a planar shape with low opening angles...

In 90% of stages a noticeable correlation was perceived in surface pressure responses to microseismic events. Wider...

... microseismic events induced by the injection of fracturing fluid ( Warpinski, 2009 ). To obtain the location of microseismic events, the conventional method adapts P -wave polarization (i.e., particle motion for incident angle) and S-P travel time difference (i.e., hypocenter distance and depth) methods...

.... In microseismic monitoring, the energy emissions from rock deformation, in the form of micro-earthquakes, is captured by downhole or surface arrays of receivers or geophones. The arrival times and amplitudes of received P- and S-waves are then analyzed to locate the source of microseismic events...

... Abstract During hydraulic fracture stimulation of the Middle Bakken Formation, many out-of-zone microseismic events are observed in the Mission Canyon Formation located ~ 800 ft above the Middle Bakken. These microseismic events follow an abnormal sequence, where the events are first located...

... with subsurface fluid injection is mainly caused by shear failure. Microseismic events can be separated into two main categories: near-field events and far-field events. Near-field events are the microseismic events close to the induced fracture (i.e. hydraulic fracture); as a result, the stress shadow effect...

The number of events recorded on each well tends to have a positive correlation to that well's initial production, while the magnitude of those events does not tend to be a good indicator of production in all zones. Fracture models created from located microseismic events also tend to correlate well...
