“…One of the effective methods for controlling asphaltene deposition is to use chemical additives such as surfactants [3,4], polymeric inhibitor [5] and adsorbents [6]. Up to now, several adsorbents were used for asphaltene adsorption from oil solution such as mineral surfaces (kaolin, calcite and dolomite) [6], clay and reservoir rocks [7,8], metal surfaces (stainless steel and gold) [9,10] and several kinds of metal and metal oxide nanoparticles (MgO, TiO 2 , NiO, CaO, Fe 3 O 4 , Al 2 O 3 , etc) [11][12][13][14][15][16][17][18]. The reasons of interest on using nanoparticles in recent years for asphaltene adsorption are the special properties of nanoparticles such as their high surface area to volume ratio, functionalizable surface and their smaller size that cause easier transportation in porous media and enhance the performance of fluid flow and oil recovery [14][15][16].…”

-Zeolite beta nanoparticles were used as a new asphaltene adsorbent for reducing asphaltene deposition during fluid injection into a silica sand pack. At first, the asphaltene adsorption efficiency and capacity of zeolite beta nanoparticles were determined by UV-Vis spectrophotometer. It was found that the proper concentration of nanoparticles for asphaltene adsorption was 10 g/L and the maximum asphaltene adsorption onto zeolite beta was 1.98 mg/m 2 . Second, two dynamic experiments including co-injection of crude oil and n-heptane (as an asphaltene precipitant) with and without use of zeolite beta nanoparticles in the sand pack was carried out. The results showed that the use of zeolite beta nanoparticles increased the permeability ratio and outlet fluid's asphaltene content about 22% and 40% compared to without use of nanoparticles, respectively. Moreover, a model based on monolayer asphaltene adsorption onto nanoparticles and asphaltene deposition mechanisms including surface deposition, entrainment and pore throat plugging was developed to determine formation damage during co-injection of crude oil and n-heptane into the sand pack. The proposed model presented good prediction of permeability and porosity ratios with AAD% of 1.07 and 0.07, respectively.

“…In addition to the interactions at the interface, it was shown that mass transfer of natural amphiphilic species from oil to water is responsible for variations of the water pH [11][12][13][14][15][16][17][18]. We have recently used the pH changes after oil-water contact to derive the partition coefficient of oil species between oil and water [19].…”

-Asphaltenes are shown to be amphoteric, containing acidic and basic species that can ionize at low and high pH respectively when they come in contact with water. We have used a mass transfer model in order to determine the partition coefficients of asphaltenes between oil and water. We have compared the influence of type of asphaltenes on interfacial tension and on mass transfer between oil and water and analysed the influence of an added surfactant. We have also compared the behavior of asphaltenes dissolved in model solvents with that of diluted heavy crude oils. Although asphaltenes qualitatively reproduce the behavior of crude oil components at the oil-water interface, differences were observed, either in interfacial tensions at low pH, or in partition coefficients at high pH. These differences are due to other molecules present in crude oil, which are either more interfacially active or more soluble in water.Résumé -Influence du pH sur la tension interfaciale et les transferts de masse pour des huiles modèles d'asphaltènes. Comparaison avec le comportement du brut -Nous avons mis en évidence le comportement amphotère des asphaltènes, qui contiennent des espèces acides et basiques pouvant s'ioniser lorsqu'ils entrent en contact avec l'eau. Nous avons utilisé un modèle de transfert de masse afin de déterminer les coefficients de partage des asphaltènes entre l'huile et l'eau. Nous avons comparé l'influence du type d'asphaltènes sur la tension interfaciale et le transfert de masse entre l'eau et l'huile, et analysé l'influence d'un tensio-actif ajouté. Nous avons également comparé le comportement des asphaltènes dissous dans des solvants modèle avec celui d'un brut lourd dilué. Bien que les asphaltènes reproduisent qualitativement le comportement du brut dilué à l'interface huile-eau, des différences sont observées entre les tensions interfaciales à bas pH bas, et dans les coefficients de partage à pH élevé. Ces différences sont dues à d'autres molécules présentes dans le brut, qui sont soit plus interfacialement actives, soit plus solubles dans l'eau.

“…Adsorption precedes asphaltenic, resinous and paraffinic formation of macroscopic deposits on reservoir's pores and on surfaces of production equipment. Early colmatage of reservoir may lead to premature well shutdown (Ekholm et al, 2002). Surface layers of asphaltenes and resins can change rock characteristics.…”

“…Asphaltene and resin adsorption was studied by a great number of research groups (Ekholm et al, 2002;TatNIPI, 1988;Balabin&Syunyaev, 2008;Syunyaev et al, 2009;Acevedo et al, 2000;Lopez-Linares et al, 2006;Gonzalez&Middea, 1987;Drummond&Israelachvili, 2004;Toulhoat et al, 1994;Akhlaq et al, 1997;Dudasova et al, 2007;Alboudwarej et al, 2005;Batina et al, 2003;Batina et al, 2005;Castillo et al, 1998;Acevedo et al, 1998;Acevedo et al, 2000;Acevedo et al, 2003;Ekholm et al, 2002;Xie&Karan, 2005;Dudasova et al, 2008;Rudrake et al, 2009;Abdallah&Taylor, 2007;Labrador et al, 2007;Turgman-Cohen et al;.
