The depletion of conventional resources and steady increase in the global oil demands has
led to the shift of attention to the unconventional resources which are difficult to extract due …

In chemical enhanced oil recovery (cEOR) techniques, surfactants are extensively used for
enhancing oil recovery by reducing interfacial tension and/or modifying wettability. However …

The swelling of shale formation upon exposure to water-based drilling fluids leads to several
problems. Common shale (clay) inhibitors used in the industry have several shortcomings …

To address chromatographic separation issues encountered with surfactant-polymer
composite systems, a functional polymer (PAA-NA) was synthesized from acrylamide, 2 …

Effective flotation separation of magnetite from iron-bearing silicate minerals is difficult with
conventional collectors because of their similar surface properties. In this work …

Three gemini non-ionic surfactant-based polyethylene oxide with variable hydrophobic tails;
8 carbons (GPEOC), 12 carbons (GPEOL), and 16 carbons (GPEOP) have been synthesized …

This study was aimed at understanding how the interfacial tension (IFT) between novel
ethoxylated cationic gemini surfactants and oil is affected by various spacer types. These …

When applied to extra-heavy oil, conventional polymer surfactants exhibit poor efficacy in
reducing viscosity and have limited adaptability. In this work, a novel amphiphilic polymer …

Surfactant tolerance in the presence of mono and divalent reservoir ions, as well as the
solubility of surfactant in high salinity and low salinity brine, are the two major requirements …

Hydration of shale formation by water‐based drilling fluids leads to several problems, such
as the collapse of boreholes, tight holes, and stuck pipe, which may impede further drilling …
