A high-efficiency anionic surfactant alcohol ethoxylate sodium hydroxypropyl sulfonate
(AEOSHS) suitable for enhancing heavy oil recovery has been synthesized through …

The anionic wormlike micelles prepared from the amino acid surfactant has multiple pH and
temperature responses. By adjusting the pH value of oleoyl sarcosine (OS) aqueous …

Chemical flooding is a very important method to the efficient development of a heavy oil
reservoir. A clear understanding of the relationship between emulsification characteristics of …

A novel pseudo-Gemini collector (PGC) featuring pH-responsive collecting power and
enhanced selectivity is developed for flotation recovery of fine copper oxides from silica. The …

Herein, we describe pH-responsive Pickering emulsions stabilized by a sodium carboxylate-
derived selenium surfactant (C10-Se-C10·(COONa) 2) in combination with positively …

In water-based oil sands extraction, the recovery of ultra-heavy oil is determined by two
essential stages: liberation and aeration. However, these two stages prefer opposite water …

At present, many researchers are paying attention to pseudogemini surfactant system. In our
previous study, oleic-acid-based pseudogemini surfactants (D-OA) assembled by …

Asphaltene deposition is a problem that occurs in oil operations, affecting most types of
crude oil. Inhibitor/dispersant products are used to address this issue. A systematic review of …

Cette thèse a pour vocation d'étudier l'évaporation thermique d'une goutte de sang et
d'analyser topographiquement les motifs induits afin de développer des méthodes d'aide au …

To explore the synergistic mechanism of polymer and surfactant in the binary combination
flooding of low-permeability reservoirs, the adaptability experiment of polymer salt-resistant …
