“…In the second region (spectra 1 and 2 in Fig. 4), where the average droplet size is much higher than the wavelength and light scattering dominates, if the average droplet size decreases then the total chemical engineering research and design x x x ( 2 0 1 4 ) xxx-xxx measured absorbance also decreases; this trend is similar to that reported by Sjöblom et al (2003) and Kallevik et al (2000).…”

“…As it can be seen, the decrease of D(4,3) values shifts the baseline of the absorbance spectra, demonstrating the sensitivity of the NIR spectrophotometer to the emulsion droplet size. The same behavior regarding changes in the NIR spectra by WC and droplet sizes was observed elsewhere [23,24,33].…”

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.
