INDUCED SEISMICITY. Seismicity triggered by fluid injection-induced aseismic slip.
Anthropogenic fluid injections are known to induce earthquakes. The mechanisms involved are poorly understood, and our ability to assess the seismic hazard associated with geothermal energy or unconventional hydrocarbon production remains limited. We directly measure fault slip and seismicity induced by fluid injection into a natural fault. We observe highly dilatant and slow [~4 micrometers pe...
متن کاملFluid-induced Seismicity
The characterization of fluid-transport properties of rocks is one of the most important, yet difficult, challenges of reservoir geophysics, but is essential for optimal development of hydrocarbon and geothermal reservoirs. Production of shale oil, shale gas, heavy oil and geothermal energy, as well as carbon-dioxide sequestration, are relatively recent developments where borehole fluid injecti...
متن کاملFluid-injection induced seismicity in the Cooper Basin (Australia): spatial, temporal, and energy characteristics
Induced seismicity has been recognized as a concern in subsurface industrial operation, and particularly at fluid-injection sites in major oil and gas exploitation plays, where hydraulic stimulations are conducted to increase rock permeability. Induced seismicity occurs also in Enhanced Geothermal Systems (EGS), where hydraulic fracturing is used to accelerate heat extraction from the rock. If ...
متن کاملInduced seismicity associated with fluid injection into a deep well in Youngstown, Ohio
[1] Over 109 small earthquakes (Mw 0.4–3.9) were detected during January 2011 to February 2012 in the Youngstown, Ohio area, where there were no known earthquakes in the past. These shocks were close to a deep fluid injection well. The 14 month seismicity included six felt earthquakes and culminated with aMw 3.9 shock on 31 December 2011. Among the 109 shocks, 12 events greater than Mw 1.8 were...
متن کاملHydrogeologic controls on induced seismicity in crystalline basement rocks due to fluid injection into basal reservoirs.
A series of Mb 3.8-5.5 induced seismic events in the midcontinent region, United States, resulted from injection of fluid either into a basal sedimentary reservoir with no underlying confining unit or directly into the underlying crystalline basement complex. The earthquakes probably occurred along faults that were likely critically stressed within the crystalline basement. These faults were lo...
