We first obtain preliminary estimates of fracture geometry based on microseismic events’ spatial location and density with respect to the perforation cluster location. We then tune key completion...

... 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). The second problem was to use artificial neural networks for solving the eikonal equation. The main result...

... triggered seismic data in real-time. Depending on the severity of the microseismic events detected, operators are immediately alerted via email and text messages, so that remedial actions may be swiftly initiated. The utility of this integrated system is further exemplified by the massive reduction...

..., the microseismic event cloud forms a planar shape with low opening angles (failed by shear), indicating fracture slippages around the major hydraulic fracture. On the other hand, in the case of a complex fracture network with the absence of any major hyfraulic fracture, the triggering front grows non-linearly...

... results measured in the first pad indicated a 50% increase in the number of microseismic events in the well with diverter along with subtle shifts in both frac geometry and orientation. In 90% of stages a noticeable correlation was perceived in surface pressure responses to microseismic events. Wider...

... a velocity model suitable for mapping microseismic events. These models typically assume lateral homogeneity which may not honor the geologic properties of the medium being modeled ( Grechka and Yaskevich 2013 ). Perhaps we can go further and extract more value from microseismic surveys by simultaneously...

... 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...
