Abstract: Recent studies have suggested the possibility of spontaneous emulsification as a mechanism for enhanced oil recovery (EOR). The discussions have, however, remained essentially qualitative. A study was therefore undertaken to estimate quantitatively the contribution of spontaneous emulsification as an EOR mechanism. The tests were conducted on several bulk liquid/liquid systems as well as by displacement experiments in unconsolidated synthetic sand packs. Spontaneous emulsification was found to be a mechanism f… Show more

“…It describes the characteristics of internal phase fluids being dispersed into external phase fluids to form emulsions, reflecting the difficulty of oil–water emulsification. Emulsion stability refers to the characteristics of the emulsion to delay oil–water separation under static conditions, describing the nature of maintaining the oil–water two-phase dispersion state. The stability of emulsions varies greatly as a result of the different types, compositions, and emulsifiers of oil and water phase substances in emulsions.…”

“…In chemical flooding processes, emulsification of oil displacing agents with remaining oil and residual oil constitutes an important contribution to enhanced oil recovery. In recent years, study of emulsification in the oil displacement process has garnered increasing attention, helping in better understanding of the emulsion flooding mechanism. Through experiments, some researchers have found that one of the main mechanisms for the emulsification process to improve microscopic oil displacement efficiency is through higher displacement efficiency of the residual oil film. It was found that the emulsion formed in reservoir pores can effectively block high conductivity channels and thus improve sweep efficiency. , As a result, some researchers have begun to regard emulsification as the main driver in chemical flood enhanced oil recovery. , …”
