“…At equilibrium this can be described by the following equation: For the adsorption of non-ionic surfactants from aqueous solutions on a porous surface (i.e., silica gels) the adsorption isotherm exhibits a sigmoidal shape (S-shape) as shown by several studies [19,27,28]. Moreover, Zhu and co-workers found that their two-step model with S-shape is also applicable to non-polar organic solvent [29]. For instance, this statement is consistent with calorimetric data according to the investigation of Findenegg et al on adsorption of decan-1-ol from heptane at solution/graphite interface [30].…”

“…In this model, two steps are considered for asphaltene adsorption. The first adsorption step is taken as the adsorption of asphaltenes in solution to the surface of the rock, and the second adsorption step is taken as the adsorption of asphaltenes in solution to those asphaltenes already adsorbed to the rock, as follows [31]:…”

Les effets du taux d'injection de pe´trole sur la de´position d'asphalte`ne et la re´duction de la perme´abilite´ont e´te´e´tudie´s. Les re´sultats expe´rimentaux montrent qu'une augmentation du de´bit d'injection de pe´trole peut causer une augmentation du de´poˆt d'asphalte`ne et une re´duction de la perme´abilite´. Il est aussi observeq ue, pour des de´bits d'injection plus faibles, une diminution monotone de la perme´abilite´des e´chantillons rocheux peut eˆtre obtenue en augmentant le de´bit d'injection, alors que pour des de´bits d'injection plus e´leve´s, apre`s une diminution de la perme´abilite´de la roche, une tendance a`l'augmentation est observe´e avant d'atteindre un e´tat stationnaire. Les re´sultats expe´rimentaux montrent aussi que le type de roche peut affecter la quantite´d'asphalte`ne de´pose´e, et que la de´position d'asphalte`ne est lie´e a`diffe´rents me´canismes dans les carottes de forage de gre`s et de carbonate. Il est mis en e´vidence que les me´canismes d'adsorption et de colmatage jouent un roˆle plus important dans les carottes de carbonate que dans ceux de gre`s. Ces re´sultats indiquent que les volumes de pore du pe´trole brut injecte´sont plus e´leve´s dans les e´chantillons de gre`s que dans ceux de carbonate. On peut ainsi en de´duire que trois types de de´poˆts peuvent avoir lieu durant l'injection de pe´trole brut : un de´poˆt continu pour les forages af aible perme´abilite´, un colmatage lent et progressif pour les forages a`haute perme´abilite´et un de´poˆt progressif pour les forages a`moyenne perme´abilite´. Les re´sultats expe´rimentaux indiquent ainsi qu'une augmentation de la pression de produc...

“…A particularly common occurrence is what appears to be a two-rate type process, where a fast initial adsorption step is followed by a slower stage of adsorption before equilibrium is reached. This is generally not explained by any of the 'traditional' isotherms listed above, and so a range of new models have arisen in the last few decades in an attempt to provide a physical rationalization for the behavior seen [6][7][8][9][10][11][12][13]. Typically, the two-rate adsorption behavior can be a result of four possibilities (or a combination of them) -two-sites with different energies [14][15][16][17][18], two species with different adsorption rate constants (or diffusion coefficients) [19], rearrangement of adsorbed molecules on the surface [20][21][22][23] or bilayer adsorption [24][25][26][27][28].…”
