Injection induced seismicity
WebbCan Induced Seismicity Decrease Under a Long Strong Anthropogenic Excitation? Rodkin MV1,2 and Lyubushin AA3 ... [6,9,12], where the connection between seismicity and the injection regime was shown and certain differences in the parameters of induced and natural seismicity were detected. Webb11 apr. 2024 · The injection parameters strongly influence the rupture mechanism that can be interpreted as due to the opening/closing of a fracture network inside a fault zone of a pre-existing thrust fault. For the case of the reservoir-induced seismicity, no direct correlations are observed with the loading/unloading of the reservoir.
Injection induced seismicity

The earthquake likelihood is strongly dependent on the duration of injection. For a fixed total injected volume, a shorter injection duration (or, equivalently, a higher injection rate) results in a higher likelihood of earthquake triggering (Supplementary Note 9). To further understand how injection rate … Visa mer When fluid is injected into a faulted reservoir, the pore pressure change induces effective stress variations in the reservoir and surrounding rock (Fig. 1a). To model the effects of variations in effective normal … Visa mer The stability of steady frictional sliding to small perturbations in velocity, which determines whether motion is by slow steady-sliding or violent stick-slip, depends on the evolution of the frictional resistance. Stick-slip occurs … Visa mer To study the influence of reservoir properties on the critical injection rate, above which earthquakes are induced, we model the occurrence … Visa mer Our findings, if they are applicable to natural faults, hold interesting and important implications for induced seismicity. The poroelastic spring–slider may be viewed as a simple model of a fault segment in … Visa mer Webb25 mars 2024 · Induced seismicity observed during Enhanced Geothermal Stimulation at Otaniemi, Finland is modeled using both statistical and physical approaches.

We … Webb12 feb. 2024 · Even when injection is terminated, diffusion still causes the pressure to increase at some locations, which may lead to post-injection seismicity. In fact, some of the larger events in Enhanced Geothermal Systems (EGS) have occurred after stimulation was stopped, e.g. at Soultz-sous-Forêts and Basel.
WebbWe propose a method for determining the possible magnitude of a potentially largest induced seismic event derived from the Gutenberg–Richter law and an estimate of total released seismic moment. We emphasize that the presented relationship is valid for induced (not triggered) seismicity, as the total seismic moment of triggered … Webb20 apr. 2015 · For instance, fluid injection in sedimentary rocks within the overpressure ranges that are reasonable for CO 2 injection, i.e., Δ P < 10 MPa, do not usually induce seismicity (3 sites with seismic events greater than magnitude 2 out of 23 injection sites reviewed by ref. 16 ).
