Fluid-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 کاملTidally Induced Changes of Fluid Pressure, Geothermal Temperature and Rock Seismicity
This paper analyzes and summarizes the numerous types of variations of groundwater pressures (heads), mid-oceanic ridge borehole temperatures and microseismicity in response to tidal forcing in coastal aquifers and deep sea sediments. Tidally related data obtained from various sources were filtered and processed by means of classical harmonic analysis to extract the amplitudes of pressure and t...
متن کاملINDUCED 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 کاملThe role of fluid pressure in induced vs. triggered seismicity: insights from rock deformation experiments on carbonates
Fluid overpressure is one of the primary mechanisms for tectonic fault slip, because fluids lubricate the fault and fluid pressure reduces the effective normal stress that holds the fault in place. However, current models of earthquake nucleation, based on rate- and state- friction laws, imply that stable sliding is favoured by the increase of pore fluid pressure. Despite this controversy, curr...
متن کاملCoupled Vibration of Partially Fluid-Filled Laminated Composite Cylindrical Shells
In this study, the free vibration of partially fluid-filled laminated composite circular cylindrical shell with arbitrary boundary conditions has been investigated by using Rayleigh-Ritz method. The analysis has been carried out with strain-displacement relations based on Love’s thin shell theory and the contained fluid is assumed irrotational, incompressible and inviscid. After determining the...
