Probabilistic Seismic Hazard Analysis for Induced Seismicity

2014
Probabilistic Seismic Hazard Analysis is currently the most common approach to seismic hazard analysis. For application to induced seismicity, a major challenge is the fact that the hazard is inherently nonstationary. In this paper we describe the theoretical extension of PSHA to a non-stationary context.

Application of seismic tomography to induced seismicity investigations

Proceedings of Rock Mechanics in Petroleum Engineering, 1994
Abstract Two case studies are presented, which highlight the potential application of seismic velocity imaging to induced seismicity investigations. Velocity images may be produced using data currently recorded with seismic monitoring arrays.

Mitigating injection-induced seismicity to reduce seismic risk

Earthquake Spectra, 2021
Over the past decade, parts of the central United States have experienced elevated number of earthquakes and seismic damage to buildings and infrastructure. These earthquakes are caused by underground injection of wastewater from oil and gas operations, which increases pore pressures, in some cases leading to slip on faults in the geologic basement ...

Seismic Hazard and Hydraulic Fracture-induced Seismicity

Proceedings, 2015
Traditionally, to relate the seismic hazard potential in seismically active areas, empirical ground motion prediction equations (EGMPE) are used to relate event parameters like magnitude and location to site characteristics such as peak ground acceleration (PGA) or peak ground velocity (PGV) which tend to be how building codes are parametrized.

Acoustically induced seismic waves

The Journal of the Acoustical Society of America, 1986
When an airborne acoustic wave is incident at the ground surface, energy is coupled into the ground as seismic motion. In a previous publication [Sabatier et al., J. Acoust. Soc. Am. 78, 1345–1352 (1986)] the ground surface was modeled as an air-filled poroelastic layer overlying a semi-infinite, nonporous elastic substrate.

Induced seismicity in Canada

Engineering Geology, 1976
Abstract The annual and cumulative catalogues of Canadian earthquakes prepared by the Department of Energy, Mines and Resources, are critically examined to determine if they contain examples of induced seismic activity caused by fluid injection in oil fields, by the impounding of water in large reservoirs or by mining.

RESERVOIR INDUCED SEISMICITY

ISET Journal of Earthquake Technology, 1991
The literature on reservoir induced seismicity begins with the discussion of the seismic events at Lake Mead (Hoover Dam) on the Nevada-Arizona border (Carder, 1945), which was the first time such seismic phenomena had been clearly recognized. In retrospect, it appears that an even earlier example had occurred at Lake Marathon, Greece, where induced ...

Probabilistic Seismic Hazard Analysis for Induced Seismicity

2020
In recent times, there has been increased seismicity in geologically stable basins in North America, thought to be associated with hydraulic fracturing and/or waste water disposal activities. Induced events could generate a seismic hazard higher than natural seismicity, particularly in areas with small-to-moderate natural background seismicity, leading

Fluid-Induced Seismicity

2015
The characterisation 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. This book provides a quantitative introduction to the underlying physics, application, interpretation, and hazard aspects of fluid-
