DOI: 10.1063/5.0217315
Abstract: The immiscible displacement of a wetting fluid by a non-wetting fluid in rough fractures is crucial in many subsurface applications. Hydrodynamic-scale modeling of such drainage flows is challenging due to the complex interaction between the… read more here.

DOI: 10.3390/en17040956
Abstract: The deployment of proppant to fracture shear is a promising approach to stimulating hydraulic permeability in fractured reservoirs. However, the interactive effects of proppant and surface roughness have not been clearly revealed. To better understand… read more here.
