Enhanced asphaltene degradation using piezocatalytic technology: A novel approach for sustainable oilfield operations

Results in Engineering
Asphalt or oil spills containing asphaltene can contaminate soil, water bodies, and ecosystems. Natural balances are disrupted by this contamination. Asphaltene contaminates water sources such as rivers, lakes, and aquifers, making them unfit for human ...

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 ...

Prediction of asphaltene precipitation upon injection of various gases at near-wellbore conditions: A simulation study using PC-SAFT EoS

Oil & Gas Science and Technology, 2019
The depletion of oil reservoirs and increased global oil demand have given impetus to employ various secondary and tertiary oil recovery methods. Gas injection is widely used in both secondary and tertiary modes, though the major problem associated with ...

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 ...

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 ...
