Global review of induced earthquakes in oil and gas production fields

地球与行星物理论评, 2021
Human-induced earthquakes have a long history, which could be caused by impoundment of reservoirs, underground mining, geothermal operations, oil and gas production, and wastewater injection.

Induced Seismicity Completeness Analysis for Improved Data Mining

Frontiers in Earth Science, 2021
The study of induced seismicity at sites of fluid injection is paramount to assess the seismic response of the earth’s crust and to mitigate the potential seismic risk. However statistical analysis is limited to events above the completeness magnitude mc,

Quantitative assessment of the spatio-temporal correlations of seismic events induced by longwall coal mining

Journal of Rock Mechanics and Geotechnical Engineering, 2022
Rock failure process as a natural response to mining activities is associated with seismic events, which can pose a potential hazard to mine operators, equipment and infrastructures. Mining-induced seismicity has been found to be internally correlated in

Mining Induced Seismic Event on an Inactive Fault [PDF]

Acta Geophysica, 2015
On 19 March 2013, a tremor shook the surface of Polkowice town where the Rudna Mine is located. This event, of ML = 4.2, was the third most powerful seismic event recorded in the Legnica Glogow Copper District (LGCD). Inhabitants of the area reported that the felt tremor was bigger and lasted longer than any other ones felt in the last couple of years.

Spatial Multifractal and b Value Characteristics of Mine Earthquakes under High Tectonic Stress

Geofluids, 2022
Mining-induced earthquake is one of the common risk factors affecting the safety of mining engineering. In order to reveal the information characteristics of mine seismicity and predict the high-energy mine seismicity, based on the microseismic ...

Regional variations in the diffusion of triggered seismicity [PDF]

, 2005
We determine the spatiotemporal characteristics of interearthquake triggering in the International Seismological Centre catalogue on regional and global scales. We pose a null hypothesis of spatially clustered, temporally random seismicity, and determine

Enhanced 3D velocity structure, seismicity relocation and basement characterization of Changning shale gas and salt mining regions in southern Sichuan basin

Frontiers in Earth Science, 2023
Current extensive seismicity in southern Sichuan Basin is ascribed to the reactivation of pre-existing faults, as a result of prolonged fluid injection for salt mining and shale gas development, respectively.

Effect of mining and geology on mining-induced seismicity – a case study [PDF]

, 2022
Mining-induced seismicity is a commonly occurring phenomenon in underground mines. This poses a greater challenge to the safety of the mining operation.

Injection-Induced Seismic Risk Management Using Machine Learning Methodology – A Perspective Study

Frontiers in Earth Science, 2020
Effective identification of induced seismicity and real-time management of seismic risks are hot topics due to increasing induced seismicity in areas related to energy exploitation.

A review of unloading-induced fault instability

Underground Space, 2021
Induced seismicity associated with underground space creation and resource extraction has become a matter of global concern. However, our ability to predict and mitigate anthropogenic geohazards is still woefully inadequate.
