... fractures are sub-vertical, occurring in swarms and forming well-defined and separate Frac-Zone-Domains (FZDs). In HFTS2, both the number of microseismic events and strain interactions increase as stimulation progresses within the pad. The observed spatial and temporal dependencies in the MS and LF-DAS...

... of a microseismic monitoring effort, because the generation of a microseismic event is not immediately diagnostic of fluid-induced fracturing, the event clouds tend to overestimate the effective area of fracturing. In order to gain further insight into how microseismic events describe effective fracture growth...

The distribution of microseismic events away from the well both vertically and laterally is also influenced by the lithology variation, as well as the presence of pad-sized faults.

... observed from microseismic data. Available microseismic data was used to validate the DFN and UFM models. The DFN model showed natural fracture intensity variation along and away from the wellbore and for the most part agreed with the footprint of the microseismic events. This variation was also captured...
