... fracturing fault activation. The authors used increase or decrease in the delay time. To interpret the regional array data over a pad from Fox Creek, Alberta, and results, we modelled the static stress transfer produced by found a change in orientation and strength of anisotropy slip on the faults that had...

... observed are strike-slip events commonly related to fault activation. These strike-slip events are usually very small; however, there are cases where they are large enough that they are detected on surface seismometers. These cases of fault-related seismicity, in the absence of microseismic monitoring...

... deformation, and the resulting stress interactions, may contribute to further seismicity. In this paper we use a dataset acquired during hydraulic fracturing to calculate elastic stress transfer during a period of fault activation and induced seismicity. We find that elastic stresses may have weakly promoted...

... In earthquake seismology, the seismicity magnitude distributions generally follow the well-known Gutenberg-Richter relationship with slope defined by the b-value; yet, observed drops from b?2 to b?1 have been interpreted to indicate fault activation during hydraulic-fracturing completions...

... ABSTRACT Coupled fluid flow and geomechanical modeling with explicit and physics based modeling of fault activation is employed to investigate under what conditions a felt seismic event could be induced during deep injection activities associated with Geologic Carbon Storage (GCS) or shale gas...

... of tectonically stressed faults leading to triggered seismicity. A coupled hydrogeomechanical model is used here to examine fault activation during multi-stage hydraulic fracturing and to examine operational scenarios. The model shows that the relative stage sequencing relative to the direction of fault slip can...
