It is a well-established fact that that wettability alteration toward more wetness condition could resultants in improve oil recovery. Understanding the wettability alteration mechanisms in multiphase flow in porous media is crucial for the efficient development of enhanced oil recovery techniques. Chemical solution such as surfactant increase the water wetness of rock surface which increase the relative permeability of the oil phase. However, the wetting states of reservoir is determining how the fluids are distributed in the pore space. A key aspect of wettability alteration process isinteractions in crude oil-brine-rock systemwhich is characterized by severalmethods.
The purpose of a review is to analyze critically a modification of wettability characteristics in terms of chemical EOR methods. It consists of chemical materials, characterization methods, and EOR mechanisms. To identify any factors which are influencing the wettability of rock surface during chemical injection, responsible mechanisms involved in.
