... 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...

... hydraulic fracture stages progressively activated several parallel, critically-stressed faults, resulting in induced seismicity during the injection. The case study provides key insights about the spatial and temporal characteristics of the seismogenic faults, and the relationship to fracturing operations...

... 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...

... 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...

... ABSTRACT Stresses around a hydraulic fracture and whether the tip stresses could activate a bedding plane or weakness plane are important questions for hydraulic fracture propagation and microseismicity generation. When a hydraulic fracture activates a bedding plane or weakness plane, it could...

... Summary A coupled hydro-mechanical model is used to evaluate fault activation associated with hydraulic fracturing in the Horn River Basin. The model is used to simulate hydraulic fracture growth through a discrete fracture network, examining the pore pressure diffusion and associated...

... Summary Microseismic monitoring has long been used to monitor steam injection programs related to enhanced heavy oil recovery. It has been well established that microseismicity can be used to examine steam chamber dimensions, cap rock integrity or steam containment and fault activation...
