Wettability alteration would play a significant role in the hydrocarbon displacement as it can improve oil recovery factor both conventional and unconventional reservoirs. Therefore, accurate prediction of this parameter be importance sweep efficiencies. In paper, we aimed to experimentally investigate wettability changes presence nonionic natural surfactant (Cedar) for different carbonate mine...

research in nanotechnology in the petroleum industry is advancing rapidly and an enormous progress in the application of nanotechnology in this area is to be expected. in particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening ...

a r t i c l e i n f o Keywords: Low-salinity Waterflood LSW Brine Double-layer Sandstone Carbonate Film Low-salinity waterflooding is a relatively new method for improved oil recovery that has generated much interest. It is generally believed that low-salinity brine alters the wettability of oil reservoir rocks towards a wetting state that is optimal for recovery. The mechanism(s) by which the ...
