“…One of the current state of the art techniques for increasing the amount of crude oil from an oil field [known as enhanced oil recovery (EOR)] involves improvement of polymer characteristics such as rheological behavior with the help of NPs . Polymer flooding is a robust chemical flooding method with more than 40 years' precedent . Several research studies and field practices have shown an increasing recovery in the range of 5–30% of original oil in place by improving the mobility ratio inside porous media with the help of polymers .…”

This work aims to improve the rheological properties and stability of multiwalled carbon nanotubes (MWCNTs)/acrylamide (AA) base skeleton polymer blends at harsh environment of high salinity‐high temperature (HS‐HT) or various pH. Different co/terpolymers have been accomplished to modify the structure of AA polymer by free‐radical copolymerization of AA‐based monomers. Anionic, cationic, and hydrophobic functional groups were used for the synthesis of polyelectrolyte, polyampholytic, and partially hydrophobic AA polymer types. The conversion, molecular weight, and poly dispersity of co/terpolymers have been evaluated by nuclear magnetic resonance (1H‐NMR), gel permeation chromatography, and differential scanning calorimetry analysis. The effects of sonication power, concentration of polymer, and concentration of MWCNTs were also investigated on rheological behavior of co/terpolymers. The results show that negative polyelectrolyte and polyampholytic polymers are the best candidates for the improvement of MWCNTs/polymer stability and viscosity at HS‐HT and alkali environment, respectively. © 2018 Wiley Periodicals, Inc.

“…Many oil fields across the world are being plagued by issues with excessive water cut and dispersed leftover oil (Cheng et al, 2023; Noruzi & Sharifi, 2023; Wang et al, 2021). In response, major oilfields have used chemical EOR technology (CEOR) with the aim of achieving consistent and continuous oil production (Delamaide et al, 2014; Noruzi et al, 2023; Pope, 2007). Polymer flooding, the most popular type of chemical flooding, is an efficient way to increase oil recovery (Kamal et al, 2016; Wang et al, 2020; Zhang et al, 2019).…”

Enhancing oil recovery through surfactants has proven to be a successful strategy in recent times. However, traditional surfactants have their limitations, particularly in terms of stability under high temperatures and salinity levels. This study delved into a groundbreaking macromolecular polymeric surfactant, S‐AV, which holds the unique ability to transform rock surface characteristics, effectively stripping away residual oil while maintaining resilience against elevated temperatures and salinity. S‐AV was synthesized through a free‐radical copolymerization process, incorporating benzyl, perfluoroalkyl, alkyl‐, benzyl‐, ethylene glycol, and amide‐alkyl‐sulfonate groups, ultimately yielding a comb‐like molecular structure. S‐AV demonstrated exceptional prowess, swiftly reducing the underwater oil contact angle to 53.4° in just 48 h. This synthesized surfactant also retained its phase stability up to salinity levels of 36,000 ppm, with temperature having no disruptive impact on its phase stability performance. Furthermore, S‐AV showcased remarkable viscosity reduction in conditions of high temperature and salinity. The core flooding experiments underscored the potential of S‐AV, as its injection led to a significant oil recovery rate of up to 83%. These findings position S‐AV as a promising candidate for practical enhanced oil recovery applications.
