Fluid injection into rocks is increasingly used for energy extraction and for fluid wastes
disposal, and can trigger/induce small-to medium-scale seismicity. Fluctuations in pore fluid …

Massive fluid injection into the subsurface can induce microearthquakes by reactivating
preexisting faults or fractures as seismic or aseismic slip. Such seismic or aseismic shear …

Transmissivity of fluids along fractures in rocks is reduced by increasing normal stress acting
across them, demonstrated here through gas flow experiments on Bowland shale, and oil …

The feasibility and advantages of synchrotron imaging have been demonstrated to
effectively characterise fracture initiation and propagation in shales during indentation tests …

We present a series of controlled fluid injection experiments in the laboratory on a pre‐
stressed natural rough fracture with a high initial permeability (∼ 10− 13 m2) in granite …

This study investigates the roles of inclination angle of fracture (θ) and unloading rate of
confining pressure (U r) on the hydraulic characteristics of shale fractures during the …

Unconventional hydrocarbon resources found across the world are driving a renewed
interest in mudrock hydraulic fracturing methods. However, given the difficulty in safely …

Fluid flow in fractures has the potential to drastically change the economic, environmental,
and safety risks associated with a subsurface operation. This work focuses on the analysis of …

Highlights Thirty groups of aperture fields with different mean and standard deviation values
were attained to investigated the effect of channeling flow on the permeability evaluation …

Abstract Variability in the Lower Bowland shale microstructure is investigated here, for the
first time, from the centimetre to the micrometre scale using optical and scanning electron …
