This Protocol is a living guidance document for geothermal developers, public officials, regulators and the generalBeginning in 2009, Oklahoma experienced a surge in seismicity. This surge was so large that its rate of magnitude 3 and larger earthquakes exceeded California’s from 2014 through 2017. While these earthquakes have been induced by oil and gas related process, few of these earthquakes were induced by fracking. The fault reactivation and induced seismicity that are induced by fluid injection are more likely to occur and more serious than that induced by fluid production.

There has been a remarkable increase of induced seismicity in the Western Canada Sedimentary Basin (WCSB) since 2009 when the horizontal drilling and multistage hydraulic fracturing technologies were adopted to develop the shale reservoirs in WCSB (Atkinson et al., 2016).It is believed that some large induced seismicity events can be related to multistage hydraulic fracturing ...The principal aim of this paper is to test the likelihood of induced seismicity along fractures with certain orientations from the perspective of fault reactivation related to stress field perturbations. With the slip tendency analysis the potential for slip along any fault orientation with respect to the ambient stress field is investigated ...As illustrated through recent studies of induced seismicity in Oklahoma (Walsh and Zoback, 2016), knowledge of the current state of stress is an essential component in estimating the pore-pressure perturbation needed to trigger an earthquake on a given fault. Such analyses enable both retrospective analyses of potentialKey Points Pore-fluid pressure diffusion remains a basic mechanism for initiating induced seismicity in the vicinity of fluid injection Poroelastic stress, Coulomb static stress, and aseismic slip also contribute to triggering seismicity beyond the influence of pressure diffusionInduced seismicity is associated with deep geothermal development, where fluids circulate in the reservoir.

The general concerns about induced ...13 mar 2019 ... Induced seismicity refers to typically minor earthquakes and tremors triggered by human activity, deliberate or not.Before 2013, the only documented instance of possible induced seismicity in Kansas occurred in 1989 when small earthquakes were recorded near Palco in Rooks County, about 30 miles northwest of Hays.

This so-called “reservoir-induced” seismicity has been documented ever since large reservoirs were constructed. The first well studied example accompanied the impoundment of the Colorado River, USA by the Hoover Dam to form Lake Mead (Carder 1945 ).Induced seismicity can be of serious public concern and is capable of leading to a failed project purely due to societal pressure.
