Fault Reactivation by Fluid Injection: Controls From Stress State and Injection Rate

open access: yesGeophysical Research Letters, 2018
We studied the influence of stress state and fluid injection rate on the reactivation of faults. We conducted experiments on a saw cut Westerly granite sample under triaxial stress conditions.

Permeability evolution of fluid-injection-reactivated granite fractures of contrasting roughnesses

open access: yesUnderground Space
Fracture/fault instability induced by fluid injection in deep geothermal reservoirs could not only vary the reservoir permeability but also trigger hazardous seismicity.

Influence of Gravitational Force on Particle Motion in the Channel Flow Induced by Fluid Injection

open access: yesFluids, 2022
The motion of an individual particle in a circular channel flow induced with fluid injection is considered. Analysis takes into account drag and gravitational forces acting on an individual particle.

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

open access: yesFrontiers 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.

Nucleation and Arrest of Fluid‐Induced Aseismic Slip

open access: yesGeophysical Research Letters, 2023
Microseismicity associated with fluid pressurization in the subsurface occurs during fluid injection but can also be triggered after injection shut‐in. Understanding the extent and duration of the post‐injection microseismicity is critical to limit the ...

Sensitivity of the Seismic Moment Released During Fluid Injection to Fault Hydromechanical Properties and Background Stress

open access: yesFrontiers in Earth Science, 2021
Fluid pressure perturbations in subsurface rocks affect the fault stability and can induce both seismicity and aseismic slip. Nonetheless, observations show that the partitioning between aseismic and seismic fault slip during fluid injection may strongly

The Statistical Fingerprint of Fluid-Injection Operations on Microseismic Activity at the Val d’Agri Oil Field (Southern Italy)

open access: yesEnergies, 2023
In this paper, we examined the dynamical properties of the fluid-injection microseismicity at the Val d’Agri oil field (southern Italy) by applying different statistical methods to find correlations and common periodicities with injection parameters ...
