A Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs

Journal of Surfactants and Detergents, EarlyView.
The Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs. ABSTRACT Surfactants with both positive and negative functional groups (amphoteric or zwitterionic) are particularly advantageous in acidic oil reservoirs because they remain stable under harsh chemical conditions, tolerate acidic ...

Géochimie des résines et asphaltènes Geochernistry of Resins and Asphaltenes

Oil & Gas Science and Technology, 2006
Les produits lourds des huiles brutes (résines et asphaltènes) jouent un rôle important dans la genèse et l'accumulation du pétrole, ainsi que dans la mise en production par des méthodes conventionnelles ou par récupération assistée.

Study of Asphaltene Structure Precipitated from Oil Sands

Eurasian Chemico-Technological Journal, 2013
In the paper microscopic structure and physicochemical characteristics of asphaltenes were investigated. Asphaltene was precipitated from natural bitumen of oil sand of Munaily-Mola deposit using organic solvent of petroleum ether.

Synthesis and characterization of a highly hydrophilic nanocomposite for wettability alteration, water/oil interfacial tension reduction, and enhanced oil recovery

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 4101-4119, August 2026.
Mechanism of wettability alteration, interfacial tension reduction, and oil recovery by novel nanocomposite. Abstract The development of stable nanofluids (NFs) for enhanced oil recovery (EOR) relies on optimizing interactions between reservoir rocks and fluids.

Predicting the Solvent Properties of Supercritical Water by Integrating Solubility Parameter Theory and Molecular Force Fields

Advanced Chemical Engineering, Volume 1, Issue 1, July 2026.
The study maps molecular force fields to three‐component solubility parameters (δd, δp, and δhb). Solvent behavior reflects the competition between physical effects and hydrogen‐bond network evolution. Crucially, fluid density determines the absolute magnitude of cohesive interactions, whereas temperature functions as a key variable to selectively ...

Saline Permafrost and Cryopegs as Potentially Important Sources of CO2—Assessing Organic Carbon Mineralization Potentials on the Alaskan Coastal Plain

Global Change Biology, Volume 32, Issue 7, July 2026.
Incubation experiments reveal that potentially carbon‐rich saline permafrost and cryopegs from Arctic coastal plains exhibit CO2 production potentials comparable to active layers. This could substantially shift greenhouse gas balances, as salinity is currently not accounted for in permafrost carbon assessments.

Thermogravimetric and calorimetric dataset for extra heavy crude asphaltenes obtained by electrodeposition in the presence of magnetic field and magnetic nanoparticles

Data in Brief, 2020
A better understanding of the behavior of asphaltenes is paramount for improving processes related to heavy crude oil, such as transport. Previous research has studied its aggregation [1], as well as its average chemical structure [2].

Interfacial adsorption characteristics of surfactant‐modified nanoparticles: Equilibrium and dynamic effects of salinity at the oil–water interface

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 2940-2957, June 2026.
Surfactant‐modified nanoparticles adsorb at the oil–water interface, enabling interfacial stabilization and microemulsion formation. Abstract This study systematically investigated the interfacial behaviour of silicon dioxide (SiO2) and aluminium oxide (Al2O3) nanoparticles (NPs) functionalized with cationic (CTAB), anionic (SDS), and nonionic (Triton ...
