Paper presented at the 46th U.S. Rock Mechanics/Geomechanics Symposium, June 24–27, 2012
Paper Number: ARMA-2012-621
... ABSTRACT: The process of fluid injection into dense granular media is analyzed using the DEM code PFC2D ® coupled with a pore network scheme. A simple approach to calibrate the microscale parameters to match the permeability of a particle assembly, predicted from the Kozeny-Carman...

Paper Number: ARMA-11-228
... to the case of injection in fully saturated media with the invading fluid being the same as the pore fluid in the matrix. Depending on the injection velocity, behaviors of the particle assembly show transitions from flow in a fixed bed type of responses, to localized failure, and to the near wellbore...

... radius, and bond strengths) and the apparent material properties at the macroscopic scale (such as the compressive strength ac and the toughness Kxc). Cutting tests are then performed with a particle assembly of rock-like properties. The paper deaJs with a numerical analysis of rock cutting experiments...
