“…As a result, it is easy to understand why the mean size of the droplet will influence the demulsification efficiency of a biodemulsifier. In addition, it also found that a large variance in droplet size would improve boundary coalescence of the droplets and accelerate phase separation [27].…”

“…It has been shown that as emulsion age increases, more demulsifying agents are required to break the emulsion. However, if too much demulsifier is added it may promote the formation of an invert emulsion [8]. By eliminating the need for demulsifiers and the wait associated with gravity separation, this method of emulsion separation allows for rapid and reliable emulsion separation.…”

“…Satisfactory agreement between all three methods was found [91]. Also, other studies droplet size has been measured using microscopy techniques to investigate demulsification process to investigate the effect of the demulsifying process, aging and demulsifiers on emulsion stability [92], to calculate interfacial areas and film thickness [90]. In the following the principles of the above mentioned techniques are described briefly.…”

Stability Proxies for Water-in-Oil Emulsions and Implications in Aqueous-based Enhanced Oil Recovery

Several researchers have proposed that mobility control mechanisms can positively contribute to oil recovery in the case of emulsions generated in Enhanced-Oil Recovery (EOR) operations. Chemical EOR techniques that use alkaline components or/and surfactants are known to produce undesirable emulsions that create operational problems and are difficult to break. Other water-based methods have been less studied in this sense. EOR processes such as polymer flooding and LoSal TM injection require adjustments of water chemistry, mainly by lowering the ionic strength of the solution or by decreasing hardness. The decreased ionic strength of EOR solutions can give rise to more stable water-in-oil emulsions, which are speculated to improve mobility ratio between the injectant and the displaced oil. The first step toward understanding the connection between the emulsions and EOR mechanisms is to show that EOR conditions, such as salinity and hardness requirements, among others, are conducive to stabilizing emulsions. In order to do this, adequate stability proxies are required. This paper reviews commonly used emulsion stability proxies and explains the advantages and disadvantage of methods reviewed. This paper also reviews aqueous-based EOR processes with focus on heavy oil to contextualize in-situ emulsion stabilization conditions. This context sets the basis for comparison of emulsion stability proxies.
