Paper presented at the 57th U.S. Rock Mechanics/Geomechanics Symposium, June 25–28, 2023
Paper Number: ARMA-2023-0694
... ABSTRACT The determination of poroelastic properties for low-permeability porous media (k < 10 −18 m 2 ) is often elusive because of long periods required to dissipate or equilibrate pore pressure in tested samples. Poroelastic properties, such as the Biot coefficient, play a key role...

ABSTRACT: Accurate determination of rock mechanical properties (particularly sedimentary shales, mica and schists with foliation and bedding planes) is critical to the safe design and excavation of underground mines and tunnels. Traditional techniques to calculate rock elastic properties often...
