These estimated triggering front curves are further used to train a deep learning model for their automated prediction along individual stages of the remaining 3 wells. The triggering front curve is utilized to separate the microseismic events for each stage that are related...

Assuming a cloud of microseismic events, the contributing fracture can be defined as those induced or re-activated fractures that are propped or partially propped and can communicate to the well during production. Thus, its dimensions are smaller than the wet fracture dimensions (and, of course...
