“…For emulsification, an ionic surfactant of sodium dodecyl sulfate (sodium lauryl sulfate) was used provided by Sigma-Aldrich Chemicals Company, USA. This creamy-white powder has a great potential to form O/W emulsions due to its excellent solubility in water (soluble 1 g in 10 ml) and high HLB value of 40 (Wu et al 2014). Besides, for the oleic phase of the emulsion, gasoil with the density of 0.887 g/cc was used which is a combination of hydrocarbons with the carbon number of 10-15 consisting of saturated and aromatic hydrocarbons (Date 2011; Services 1995).…”

Emulsions are extensively prevalent in the oil industry in both advantageous and disadvantageous ways. In the literature, conventional water flooding in high permeability oil reservoirs has confronted with water channeling and poor sweep efficiency. In this paper, the remedial application of O/W emulsions as an EOR method in improving water performance is discussed. To this purpose, a series of flooding experiments were carried out in one of the Iranian oil reservoirs in reservoir condition of 75 C and 2000 psi. Then, visual stability measurements were conducted to inspect the stability characterization of the emulsion. Sodium dodecyl sulfate was applied helping simple dispersion of the gasoil into the water phase, and emulsions with water percentage of 90, 80, 70 and 60 were developed to introduce into the porous media. It was found out from flooding experiments that emulsion injection after conventional water flooding can lead to additional oil recovery (up to 20%). Besides, the emulsion with 80% water cut was determined as the optimum emulsion for injection in this reservoir considering financial aspects. Moreover, results of the stability test revealed that the aqueous phase with one wt% surfactant or higher had formed emulsions which have been stable during a long period of 6 months.

“…It is also found that the water absorption of PkE@NT film gets to 142 wt%, which shows good water absorption. Therefore, based on our previous researches [34], the composite emulsion can be a promising candidate for development of humidity controlling coatings.…”

“…Here, we focus on the preparation of composite emulsion for functional interior coatings via nano-TiO 2 stabilized Pickering emulsion polymerization. It was compared with epoxy-acrylate copolymer (GBS) via conventional emulsion polymerization in the present of compound emulsifier (0.5 wt%, sodium dodecyl sulfate: Tween-20 = 1:1) [34] and emulsifier-free epoxy-acrylate copolymer (EF-GBS), using GMA, BA and St as monomers. In order to explore the formation process of PkE@NT particles, the relationship between particle size and polymerization time was investigated.…”
