DOI: 10.1016/j.petrol.2017.10.022
Abstract: Abstract Pore-level oil mobilization is studied during low salinity waterflooding by microscopic visualization of water diffusion and osmosis in sandstone silicon-wafer micromodels. The two-dimensional water-wet micromodels apply a controlled, state-of-the-art experimental approach, with a high… read more here.

DOI: 10.1021/acs.energyfuels.8b03366
Abstract: Release of crude oil from reservoir rock by low-salinity waterflooding is thought to occur by decreasing the advancing crude oil/brine/rock water contact angle to depin three-phase contact lines (i... read more here.

DOI: 10.5614/j.eng.technol.sci.2018.50.5.4
Abstract: Wettability alteration during low salinity waterflooding (LSW) is expected to be one of the prominent reasons for enhanced oil recovery. However, the underlying mechanisms of improved oil recovery in sandstone during LSW are not entirely… read more here.
