In a wide range of operations in the petroleum industry, co-current flow of two immiscible liquids commonly occurs; therefore, an in-depth knowledge regarding these phenomena is highly necessary to predict the flow behavior during production and transportation of oil in pipeline systems. To this end, numerous researchers have applied different experimental techniques for the characterization of liquid-liquid flows in horizontal and inclined pipes. For reliable design methods, this paper reviews some of the existing experimental techniques and their applications, strengths, and limitations and gives some direction for future studies. Two main aspects of these approaches have been abundantly discussed, with an emphasis on the second one: the first section focuses on fluid physical properties and geometrical and operational variables of liquid-liquid flow experimental systems; the second one reviews the main two-phase immiscible liquid-liquid characterization methods used for flow pattern identification, velocity, and phase distribution measurements, including optical-based, irradiation, electrical, and thermal methods
