Sugar Fatty Acid Esters (SFAEs) are a class of non-ionic surfactants that can be synthesized from inexpensive natural resources. Depending on carbon chain length and nature the sugar head group, SFAEs cover wide range hydrophilic–lipophilic balance (HLB) values, which result in tunable tenside properties turn relevant for variety industrial applications. Three sugar-based (6-O-lauroyl-, 6-O-pal...

We measured interfacial tensions (IFT) of aqueous alkyl polyglucoside (APG) systems formulated with sorbitan ester-type cosurfactants against n-octane. The study focused on low to ultralow IFT systems which are relevant for enhanced oil recovery (EOR). In addition, we measured equilibrium adsorption concentrations of these surfactants and cosurfactants onto kaolinite clay, commonly found in oil...

Abstract Polymer nanohybrids have displayed great potential in remobilizing oil droplets through porous media. This research aims at providing some insights into how the hydrolyzed polyacrylamide (HPAM) polymer and Al 2 O 3 nanoparticles’ (NPs) hybrid can push crude toward producers. An understanding of what viscosity is when flowing rocks was acquired by rheological tests. Using Du Noüy ring m...

Nowadays, enhanced oil recovery is vital in improving the recovery. However, productions keep depleting due to production problem such as high surface tension and interfacial reservoirs. Therefore, chemical flooding one of methods used The synergy between Silica nanoparticle Sodium Dodecyl Sulfate has been proposed a compound for this project. major aim study was measure effectiveness synergiza...

This study experimentally investigates the effect of green polymeric nanoparticles on interfacial tension (IFT) and wettability carbonate reservoirs to effectively change enhanced oil recovery (EOR) parameters. experimental compares performance xanthan/magnetite/SiO2 nanocomposites (NC) several materials, i.e., eucalyptus plant (ENC) walnut shell ones (WNC) with performing series spontaneous im...

Surfactant flooding is an enhanced oil recovery (EOR) method for recovering residual in the reservoir through mechanism of interfacial tension (IFT) reduction and wettability alteration. Due to toxicity high cost associated with conventional surfactants, recent research has focussed on developing low-cost environmentally benign surfactants. Herein, a green surfactant extracted from Vernonia Amy...

Nanomaterials have shown significant performances in enhancing oil recovery by reducing the interfacial tension (IFT) and contact angle (CA) of rock/crude oil/water system porous media. This is evaluated synergistic impact silica–graphene quantum dots (Si–GQDs) on IFT reduction wettability alteration for purpose from carbonate reservoirs. The were synthesized combining graphene oxide silicon na...

The chemical surfactant flooding can mobilize the trapped oil by lowering the interfacial tension between oil and brine and in some cases altering the reservoir rock wettability. In this work, the effect of surfactants on oil/brine interfacial tension was experimentally investigated. First, the effect of surfactants concentration was surveyed. Afterwards, the effect of salinity on surfactant be...

Strong foam can be generated in porous media containing oil, resulting in incremental oil recovery; however, oil recovery factor is restricted. A large fraction of oil recovered by foam flooding forms an oil-in-water emulsion, so that costly methods may need to be used to separate the oil. Moreover, strong foam could create a large pressure gradient, which may cause fractures in the reservoir. ...

In this research, Sauter-mean drop diameters and the flooding behavior have been investigated experimentally in a pilot scale Kühni extraction column. The experiments were carried out in the absence of mass transfer for two different standard chemical systems. In the experiments operating parameters including agitation speed, flow rate of both liquid phases and interfacial tension have been stu...
