These results highlight the potential of surface-modified silica nanoparticles as effective foam...

... inhibitors. Concentrations range from 1.0 wt% to 0.1 wt% to identify the minimum effective dose. Solution conductivity before and after treatment were measured to assess efficacy, while scanning electron microscopy examines precipitated mineral morphology. The tests are conducted at 158°F and 338°F...

... a smaller creaming index (CI) and better emulsion stability across all concentrations. CI of 0.3 % for henna/crude oil systems could be achieved after 360 min and a significantly lower interfacial tension (IFT) was demonstrated by the interface (0.7 mN/m vs. 2.5 mN/m). Low CI values are supported by small...

... Abstract The primary objective of this work is to understand the behavior of surface-active polymer (SAP) in porous media and its interactions with high-porosity, high-permeability sandstone outcrops. The study also aims to maximize oil recovery by optimizing polymer concentration to achieve...

The polymer viscosity losses calculated for the various potential determining ions (PDIs) concentrations of 10-times spiked Mg 2+ (40 ppm) and 2-times spiked SO 4 2- (156 ppm) were 61%, and 46%, respectively. Moreover, investigating the impact of salinity on polymer adsorption revealed...
