[HTML][HTML] The use of discrete fracture networks for modelling coupled geomechanical and hydrological behaviour of fractured rocks

Q Lei, JP Latham, CF Tsang - Computers and Geotechnics, 2017 - Elsevier
We present a discussion of the state-of-the-art on the use of discrete fracture networks
(DFNs) for modelling geometrical characteristics, geomechanical evolution and …

Inferring earthquake physics and chemistry using an integrated field and laboratory approach

A Niemeijer, G Di Toro, WA Griffith, A Bistacchi… - Journal of Structural …, 2012 - Elsevier
Earthquakes are the result of a combination of (1) physico-chemical processes operating in
fault zones, which allow ruptures to nucleate and rock friction to decrease with increasing …

Investigation of injection-induced seismicity using a coupled fluid flow and rate/state friction model

MW McClure, RN Horne - Geophysics, 2011 - library.seg.org
We describe a numerical investigation of seismicity induced by injection into a single
isolated fracture. Injection into a single isolated fracture is a simple analog for shear …

[BOOK][B] Modeling and characterization of hydraulic stimulation and induced seismicity in geothermal and shale gas reservoirs

MW McClure - 2012 - search.proquest.com
The classical concept of hydraulic fracturing is that large, wing-shaped tensile fractures
propagate away from the wellbore. However, in low matrix permeability settings such as …

Damage zone heterogeneity on seismogenic faults in crystalline rock; a field study of the Borrego Fault, Baja California

GA Ostermeijer, TM Mitchell, FM Aben… - Journal of Structural …, 2020 - Elsevier
Complex fracture damage around large faults is often simplified to fit exponential or power
law decay in fracture density with distance from the fault. Noise in these datasets is attributed …

[HTML][HTML] On the role of poroelastic stressing and pore pressure diffusion in discrete fracture and fault system in triggering post-injection seismicity in enhanced …

IR Kivi, V Vilarrasa, KI Kim, H Yoo, KB Min - International Journal of Rock …, 2024 - Elsevier
Injection-induced seismicity has become one of the most critical challenges for the

Rough faults, distributed weakening, and off‐fault deformation

WA Griffith, S Nielsen, G Di Toro… - Journal of Geophysical …, 2010 - Wiley Online Library
We report systematic spatial variations in fault rocks along nonplanar strike‐slip faults cross‐
cutting the Lake Edison Granodiorite, Sierra Nevada, California (Sierran wavy fault) and …

Elastic properties of fractured rock masses with frictional properties and power law fracture size distributions

P Davy, C Darcel, R Le Goc… - Journal of Geophysical …, 2018 - Wiley Online Library
We derive the relationships that link the general elastic properties of rock masses to the
geometrical properties of fracture networks, with a special emphasis to the case of frictional …

The initiation of brittle faults in crystalline rock

JG Crider - Journal of Structural Geology, 2015 - Elsevier
Faults in the upper crust initiate from pre-existing (inherited) or precursory (early-formed)
structures and typically grow by the mechanical interaction and linkage of these structures …

An empirically based steady state friction law and implications for fault stability

E Spagnuolo, S Nielsen, M Violay… - Geophysical Research …, 2016 - Wiley Online Library
Empirically based rate‐and‐state friction laws (RSFLs) have been proposed to model the
dependence of friction forces with slip and time. The relevance of the RSFL for earthquake …
