Abstract The focus of this study was the experimental determination of surfactant adsorption during low salinity water injection combined with surfactant flooding (LSW-SF) into an oil reservoir and development of an analytical model to predict this a

Molecular weight fractionation via stepwise precipitation or chain scission is performed on four pour point depressant polymers to study the pour point reduction mechanism. An homologous series of model oils is prepared by dissolving 5 wt % of a sing

Molecular Crystals and Liquid Crystals (MCLC)
Vapor–liquid equilibria data of three poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)/water liquid crystals (LCs) with CO2 has been obtained up to 6 bar. The investigated LCs consist of 60% (EO)3(PO)50(EO)3 (Pluronic L81), 70% (EO)8

Pour point depressant (PPD) activity mechanisms include solubilization, morphology alteration, and steric/entropic repulsion. A wealth of complex intermolecular interactions governs PPD efficacies in real crude compositions. The current study utilize

Rheological measurement of wax–oil gel breakage is highly susceptible to the phenomenon of adhesive breakage, hindering instrument-scale replication of cohesive breakage processes. Adhesive breakage measurements are notoriously irreproducible due t

The influence of microcrystalline wax addition upon the rheological properties of model wax-oil gels is investigated. Addition of less than 1 wt % microcrystalline wax to a model oil consisting of 5 wt % macrocrystalline wax in dodecane shows no sign
