The wettability of carbonate rocks is often oil-wet or mixed wet. A large fraction of oil is still
remained in carbonate reservoirs, it is therefore of particular significance to implement …

Surfactant enhanced oil recovery (EOR) includes surfactant flooding and surfactant
stimulation. The main functions of surfactants are to reduce interfacial tension and wettability …

Laboratory experiments and field trials have shown that oil recovery from carbonate
reservoirs can be increased by modifying the brine composition injected during recovery in a …

Changing the wetting state of materials is a growing field of research in many areas of
engineering and science. In the oil industry, the term wettability alteration usually refers to …

The success of oil recovery from fractured low permeable carbonates by water injection is
dictated by the wetting properties of the rock surface. Potential determining ions like Ca2+ …

The wettability of carbonates is dictated by the stability of the water film between the rock
and the oil phase, which is related to the Zeta-potentials of the oil–water and water–rock …

The goal of the present paper is to provide a comprehensive review of the literature
describing the physical and chemical mechanisms for enhanced oil recovery under smart …

Wettability alteration is an important method to increase oil recovery from oil-wet carbonate
reservoirs. Chemical agents are used as wettability modifiers in carbonate systems; …

Surfactant-based chemical-enhanced oil recovery (EOR) methods have been recognized to
be effective in both conventional and unconventional oil reservoirs. However, the nanopore …

To exert the imbibition between cracks and matrix effectively and enhance the development
effect of tight oil reservoirs, a physical simulation method for imbibition in different scales of …
