Deep subsurface stimulation processes often promote fluid-rock interactions that can lead to
the formation of small colloidal particles that are suspected to migrate through the rock …

Imbibition plays a central role during multiphase flows in geological media; yet, our
understanding of imbibition dynamics across the multiscale features of rocks, including …

Geochemically driven alterations of fractures in multi‐mineral media can create altered
layers (ALs) at the fracture‐matrix interface. Spatial variations in the AL significantly …

Shales are low‐permeability caprocks that confine fluid, such as CO2, nuclear waste, and
hydrogen, in storage formations. Stress‐induced fractures in shale caprocks provide …

During hydraulic fracturing, the oxic hydraulic fracturing fluid physically and chemically alters
the fracture surface and creates a “reaction-altered zone”. Recent work has shown that most …

During the hydraulic fracturing process, an acidic hydraulic fracturing fluid (HFF) is injected
at high flow rates to break the rock and enhance its flow potential. This rock-fluid interaction …

Water-based hydraulic fracturing fluids (HFFs) can chemically interact with formation shale,
resulting in altered porosity and permeability of the host rock. Experimental investigations of …

Shales are impermeable rocks that need to be hydraulically fractured using an acidic
hydraulic fracturing fluid (HFF) to enable commercial production. The fracturing process …

Understanding flow, transport, chemical reactions, and hydromechanical processes in
fractured geologic materials is key for optimizing a range of subsurface processes including …
