"A sensitivity analysis of the effect of pumping parameters on hydraulic fracture networks and local stresses during shale gas operations"^^ . "The shale gas industry has significant impact on economies around the world, however, it is not without\r\nrisk. One of the primary concerns is felt seismicity and recent earthquakes, caused by fault reactivation\r\nrelated to hydraulic fracturing operations, have escalated uncertainty about hydraulic fracturing meth-\r\nods. Mitigating these risks is essential for restoring public confidence in this controversial industry.\r\nWe investigate the effect that changing two operational parameters (flow rate and pumping time) and\r\ndifferential pressure have on the flow distance, fracture network area and the minimum lateral distance\r\nthat hydraulic fracturing should occur from a pre-existing fault in order not to reactivate it (lateral\r\nrespect distance); thus reducing the risk of felt seismicity. Sensitivity analyses are conducted using a\r\nMonte Carlo approach. The lateral respect distance is obtained from calculations of the Coulomb stress\r\nchange of the rock surrounding the injection stage, for four stress threshold values obtained from the lit-\r\nerature. Results show that the flow rate has the smallest rate of change for fracture area (3700 m\r\n2\r\nper\r\n0.01 m\r\n3\r\n/s) and flow distance (8.3 m per 0.01 m\r\n3\r\n/s). We find that differential pressure has the largest\r\nimpact on stimulated fracture area, when less than 2 MPa, at 31,029 m\r\n2\r\n/MPa. The pumping time has\r\nthe most significant effect on the flow distance (48 m/h) and the stress threshold value the most signif-\r\nicant effect on the lateral respect distance. This study suggests that to reduce the lateral distance, a com-\r\npromise is required between flow distance and fracture area. The results obtained by this research\r\nprovide invaluable guidance for operational practice in determining the potential area of the induced\r\nfracture network and generated stress field under realistic hydraulic fracturing conditions, an important\r\naspect for risk assessments."^^ .
