Abstract
In spite of the numerous studies conducted on enhanced oil recovery using micromodels, the effect of temperature on the performance of surfactants has been grossly missing in the existing literature. Hence, this research scrutinized the variation in the performances of sodium dodecyl sulfate (SDS) as an anionic surfactant and dodecyl trimethylammonium bromide (C12TAB) as a cationic surfactant with temperature (25–98 °C) on microscopic and macroscopic scales. Viscosity, interfacial tension (IFT), and contact angle were measured using capillary tube, pendant drop and Wilhelmy Plate methods, respectively, to analyze the mechanisms of displacement and also the interaction between fluids in media with four different morphologies. The performances of brine and surfactants were found to be exceedingly temperature-dependent where this dependency was highly affected by the pores and throats structures. The measured values of the contact angle indicated a direct relationship between the temperature and the adsorption of surfactants on the glass surface. Additionally, SDS adsorption was more influenced by temperature change in comparison with C12TAB. The surfactants decreased the heterogeneity effects so that the recoveries of homogeneous and heterogeneous media were approximately equal. Nevertheless, the ultimate oil recovery of water flooding in heterogeneous micromodel was observed to be averagely 15% higher than homogeneous micromodel.
