"Correlations between formation properties and induced seismicity during high pressure injection into granitic rock"^^ . "We reviewed published results from six projects where hydraulic stimulation was performed in granitic rock. At\r\neach project, fractures in the formation were well-oriented to slip at the injection pressures used during stimulation.\r\nIn all but one case, thousands of cubic meters of water were injected, and in every case, flow rates on the\r\norder of tens of liters per second were used. Despite these similarities, there was a large variation in the severity\r\nof induced seismicity that occurred in response to injection. At the three projects where induced seismicity was\r\nsignificant, observations at the wellbore showed evidence of well-developed brittle fault zones. At the three projects\r\nwhere induced seismicity was less significant, observations at the wellbore indicated only crack-like features\r\nand did not suggest significant fault development. These results suggest that assessments of the degree\r\nof fault development at the wellbore may be useful for predicting induced seismicity hazard. We cannot rule\r\nout that the differences were caused by variations in frictional properties that were unrelated to the degree of\r\nfault development (and it is possible that there is a relationship between these two parameters). The projects\r\nwith more significant seismicity tended to be deeper, and if this is a meaningful correlation, it is unclear whether\r\ndepth influenced seismic hazard through the degree of fault development, frictional properties, or some other\r\nvariable. The results of this paper are not conclusive, but they suggest that there may be significant opportunity\r\nfor future research on identifying geological conditions that increase induced seismicity hazard."^^ .
