“…Finkle et al (9) in their study of oil-water emulsions found that waterwet particles stabilized oil-in-water emulsions, while oil-wet particles stabilized water-in-oil emulsions. Schulman and Leja (10), Lucassen-Reynder and van den Temple (11), Gelot et al (12), Menon and Wasan (13), Levine and Sanford (14), and Yan and Masliyah (15,16), among others, investigated the role of solids in stabilizing oil-water emulsions.…”

“…Optical microscopy has been used to determine size distribution or the average size diameter of emulsions as proxy of the effect of asphaltene, waxes and fine solid particles on emulsion stability [64,[86][87][88][89][90]. Eley et al [87] studied emulsions of simulated sea water and three crude oils and in a model oil consisting of n-heptane,m-xylene and asphaltenes by optical microscopy to obtain droplet diameters.…”

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.

“…[15][16][17][18][19][20][21][22][23][24] These emulsions that use solid materials as emulsifiers are called Pickering emulsions. Thus, we thought that the n-alkanol/ water emulsions using a-CD were a kind of Pickering emulsion.…”
