DOI: 10.1016/j.clay.2017.02.020
Abstract: Abstract Formation damage due to incompatibility between the formation and injected low-salinity water decreases the relative permeabilities of oil and brine, increases residual oil saturation, and decreases oil recovery. In the presence of swelling clays,… read more here.
