Effects of Surfactant and Hydrophobic Nanoparticles on the Crude Oil-Water Interfacial Tension
Energies, 2021 Surfactants and nanoparticles play crucial roles in controlling the oil-water interfacial phenomenon. The natural oil-wet mineral nanoparticles that exist in crude oil could remarkably affect water-oil interfacial characteristics.

Numerical simulations of a toroidal droplet breakup in viscous oils
AIP Advances, 2022 Toroidal droplets are inherently unstable in viscous oils; they either shrink to a single drop or break into several spherical droplets due to Rayleigh–Plateau instability.

Determination of the Minimum Miscible Pressure of the Supercritical Carbon Dioxide and the Formation Oil System by the Pendant Drop Method [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2022 Carbon dioxide miscible displacement plays an important role in the field of miscible displacement for enhanced oil recovery. However, there is a very important relationship between the formation of miscible displacement and the minimum miscible pressure.

Use of the pendant drop method to measure interfacial tension between molten polymers
Materials Research, 1999 In this paper the pendant drop method to measure interfacial tension between molten polymers is reviewed. A typical pendant drop apparatus is presented. The algorithms used to infer interfacial tension from the geometrical profile of the pendant drop are

Performance evaluation of temperature-resistant nano-surfactants [PDF]
E3S Web of Conferences, 2022 Surfactant flooding is a common technique in tertiary oil recovery. However, due to the high temperature of some reservoirs and the strong heterogeneity caused by their own geological conditions, the use of common surfactants in high-temperature ...
