Induced seismicity can be of serious public concern and is capable of leading to a failed project purely due to societal pressure. Induced seismicity in particular has proven to be a significant issue for EGS, for example. Hydraulic stimulation famously induced felt seismicity in the city of Basel, Switzerland in late 2006 (Häring et al. 2008 ...Previous analysis of the induced seismicity at Soultz-sous-Forêts yields contradicting results concerning the spatial distribution of the induced seismicity. Michelet and Toksöz [24] apply the collapsing method described in Jones and Stewart [12] to seismicity induced during the stimulation of GPK3 and obtain a volumetric rather than a planar ...Fluid injection induced seismicity has been reported since the 1960s. There are currently more than 150,000 injection wells associated with oil and gas production in 34 states in the conterminous US. Pore pressure disturbance caused by injection is generally considered the culprit for injection induced seismicity, but, not all injection causes …Geothermal Energy and Induced Seismicity Seismic events caused by human activities, or instances of induced seismicity, are an issue for a range of industries. The oil, gas, mining, hydropower and other extractive industries have long histories and substantial experience with seismicity due to hydrofracturing and other surface and

Recent seismicity in Washington County, Ohio, has been suggested to be induced by wastewater disposal operations despite injection ~2 km above the Precambrian basement. We investigated the relationships between disposal well locations and operational histories, spatiotemporal patterns of seismicity enhanced by waveform correlation, and mapped subsurface structures.

The induced seismicity screening worksheet ("ISS Worksheet") presented in this document is for informational and guidance purposes for the Bureau of Land Management (BLM) only, for the limited purpose of identifying certain low-risk projects that may be approvable without the need for a formal

1 Introduction. The unprecedented increase in the seismicity rate in the central United States (CUS) since 2008 has largely been attributed to the large volume of wastewater disposal from oil and gas production (Ellsworth, 2013; Keranen & Weingarten, 2018).In Oklahoma, several significant induced earthquakes have occurred since 2011, including the 2011 Mw 5.7 Prague earthquake and the 2016 Mw ...A newly developed modelling framework is presented which specifically focusses on the central Oklahoma case and the high-volume injection of wastewater, which led to a surge of induced seismicity. However, the modelling framework is versatile enough to be applied to any anthropogenic subsurface activities and should be seen as a good practice to manage injection while minimizing induced ...induced seismicity, earthquakes, triggering. The ability of fluid-generated subsurface stress changes to trigger earthquakes has long been recognized. However, the dramatic rise in …The USGS studies induced seismicity across the spectrum of energy issues: carbon sequestration, geothermal energy, and conventional and unconventional oil and gas.Now MIT researchers, working with an interdisciplinary team of scientists from industry and academia, have developed a method to manage such human-induced seismicity, and have demonstrated that the technique successfully reduced the number of earthquakes occurring in an active oil field.Abstract. Fluid injection into geological formations for energy resource development frequently induces (micro)seismicity. Moderate- to large-magnitude induced earthquakes may cause injuries and/or economic loss, with the consequence of jeopardizing the operation and future development of these geo-energy projects. To achieve an improved understanding of the mechanisms of induced seismicity ...Coal mining induced seismicity in the Ruhr area, Germany. Pure Appl Geophys, 167: 63–75. Google Scholar Bohnhoff M, Baisch S, Harjes H P. 2004.

The filling of surface reservoirs with water also causes earthquakes. 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 ).For induced seismicity, failure on faults is caused by stress changes resulting from anthropogenic activities, such as a gas production or water injection. Note that the initial stress on faults affected by these stress changes is not zero; gravity and plate tectonic loading have imposed an initial stress on the pre-existing faults.1 Introduction. Deep wastewater injection has been cited as a cause of induced seismicity since the 1960's Rocky Mountain Arsenal earthquakes (Healy et al., 1968) and is recognized as the most likely type of injection to induce seismicity (Weingarten et al., 2015).Several studies have shown that small magnitude stress changes (0.01-0.1 MPa) can perturb a critically stressed fault enough to ...The central United States has undergone a dramatic increase in seismicity over the past 6 years (Fig. 1), rising from an average of 24 M≥3 earthquakes per year in the years 1973-2008 to an average of 193 M≥3 earthquakes in 2009-2014, with 688 occurring in 2014 alone.The potential for fault activation and induced seismicity associated with underground fluid injection during GCS activities, has been the subject of a number of modeling studies in recent years (Cappa & Rutqvist, 2011; Jha & Juanes, 2014; Rutqvist et al., 2016; Vilarrasa et al., 2019). Fault reactivation mechanisms involve complex coupled ...2.3.1 Hydraulic Fracturing (Fracking). Hydraulic fracturing is the prime cause of a small percentage of the earth seismicity (having low magnitudes) observed in the USA. The largest hydraulic fracturing prompted earthquakes up to these dates are two M 4.4 earthquakes in central west Alberta and northeast British Columbia in Canada (British …

Here, we consider fluid-induced seismicity from 15 injection experiments at different reservoir locations. The study is a continuation of previously presented work by Shapiro et al. .

It was discovered in 1959 and production started in 1963: Continuous production leads to reservoir compaction and subsidence, gradually loading preexisting fault and induced seismicity that started about 30 yr into the production.

Induced seismicity related to fluid injection in geothermal systems has gained an increased public awareness particularly in Central Europe. The paper discusses occurrence of induced seismic events at sites of geothermal projects in comparison to natural tectonic earthquakes and other types of induced or triggered seismicity in Central Europe (i.e. in Germany and adjacent areas).

Mitigating mining-induced seismicity is a major technical challenge, and might become a limiting factor to the industry (e.g., Tang et al., 2010). During the ~ 50-year period 1949-1997, over 2000 coal bursts occurred in 33 mines in China, killing several hundred people and costing > 1300 days in lost production ( Tang et al., 2010 ).

Hydraulic fracturing (HF) can trigger induced seismicity, but documented occurrences tend to be localized compared with the regional extent of industry operations. Factors that determine intrinsic geological susceptibility of a given region to induced seismicity remain incompletely understood. To address this uncertainty, we have developed a stochastic modeling approach to enable statistical ...The sharp rise in Oklahoma seismicity since 2009 is due to wastewater injection. The role of injection depth is an open, complex issue, yet critical for hazard assessment and regulation. We developed an advanced Bayesian network to model joint conditional dependencies between spatial, operational, and seismicity parameters.Some workers distinguish between " induced " and " triggered " seismicity according to whether all or only part of the strain energy released was anthropogenic, using the term " induced " when most of the energy was anthropogenic, and " triggered " when it was predominantly of natural origin.
