AbstractXanthan gum is a biopolymer used in several different industries for a variety of applications. In the Petroleum Industry, xanthan gum has been applied in Enhanced Oil Recovery (EOR) methods for mobility control due to its Non-Newtonian rheological behavior, relative insensitivity to salinity and temperature compared to other conventional synthetic polymers, as well as its environmentally-friendly characteristics. As challenging reservoir conditions arise, candidate polymers should meet the screening factors for high salinity, high temperatures and heterogeneous reservoirs. This paper aims to evaluate the effects of temperature and monovalent salts on the rheological behavior of xanthan gum for Enhanced Oil Recovery purposes. We tested polymer solutions with brine salinities of 20,000/110,000/220,000 ppm of Sodium Chloride in a rheometer at temperatures of 23, 50, and 77°C. The results acquired showed that temperature plays a key role in viscosity and salinity protected the solution viscosity against negative thermal effects, unusually a turning point is observed where the increase in the monovalent salt content enhanced the polymeric solution viscosity. Such investigations coupled with a detailed discussion presented in the paper contribute to understand critical aspects of xanthan gum and its capability to provide basic requirements that fit desired screening factors for EOR.

<p>Janus nanoparticles have applications in many fields. Particularly, the oil industry is interested in applying them for enhanced oil recovery. Within this context, there is a need to understand the influence of the factors involved in the formulation of crude oil type emulsions over their properties and rheological behavior. In this contribution, spherical SiO<sub>2</sub> Janus nanoparticles of two different sizes were synthesized and used as surfactants for the formulation of aqueous emulsions with two model oils: namely, squalane and vacuum gas oil. Factorial experiments were designed and made to analyze the effects of the particle size of the Janus nanoparticles, the water content, the emulsification energy, and of the second and third order interactions between these variables over the droplet size distributions, polydispersity, and rheological profiles of the emulsions. On the one hand, it was found that the used Janus nanoparticles produced either water in oil (for vacuum gas oil) or oil in water (for squalane) depending on the chemistry of the oil phase. On the other hand, it was demonstrated that non-additive factors play an important role over the properties of the emulsions; especially in the case of the water in oil ones. These effects also implied non-additive correlations between the droplet size distributions of the emulsions and their rheological behavior. Therefore, this work demonstrates that simpler linear relationships do not suffice for finding the best conditions for formulating crude oil type emulsions aimed for applications such as enhanced oil recovery.</p>
