By modeling dehydration-driven fluid pressure, a new study links deep fluids to where megathrust earthquakes end and slow slip begins.

Grouting in fractured rock masses is crucial in numerous engineering projects such as tunnel seepage prevention, foundation reinforcement, and energy storage. However, slurry flow within fractures ...

Good and optimal rheology is a primary requisite for a drilling fluid to achieve better hole-cleaning and barite sag resistance. Conventional thickeners like organophilic clay that provide rheology to ...

Fluids that have a solid-like response to stress: a phenomenon called Discontinuous Shear Thickening (DST), captured by Swansea University researchers. This footage shows viscous fingering. When the ...

A new study by scientists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) shows that when a pressure disturbance moves across an ultrasoft elastic material, such as a ...

Researchers using a high-speed camera have captured the moments a fluid reacts like a solid, through a new method of fluid observation under pressurized conditions. They examined fluids that have a ...

Dilution-based dual-gradient drilling (DGD) reduces casing strings and drilling costs while increasing hole size at total depth by injecting mud down an artificially-created annulus with a different ...
