“…Other processes include precipitation of surfactants and phase trapping. Surfactant adsorption and loss have been studied extensively (Ahmadall et al 1993;Lv et al 2011;Somasundaran and Zhang 2006). Due to high surfactant costs, surfactant adsorption is considered as one of the key processes which define the overall chemical EOR performance and its economic feasibility by determining the total amount of surfactant required for the EOR process (Lefebvre et al 2012;Tay et al 2015).…”

“…Somasundaran and Zhang (2006) reported that mixed surfactants were more effective in wettability alteration than single surfactants due to synergetic effects. A naturalbased surfactant, which is low cost and environmental safety, was introduced to alter the wettability of carbonate rocks by Ahmadi et al (2015).…”

Spontaneous imbibition (SI) is one of the primary mechanisms of oil production from matrix system in fractured reservoirs. The main driving force for SI is capillary pressure. Researches relating to SI are moving fast. In the past few years, amount of literature on the development of SI with respect to many variables, such as mechanism of imbibition, scaling of imbibition data and wettability of matrix blocks. In this review, we first introduced the fundamental physics mechanism of SI through capillary tube models and micromodels. Then both conventional and more novel experimental methods of measuring oil production are discussed thoughtfully. This is followed by reviewing the oil production performance under various boundary conditions and the characteristic length in scaling equations that have been used to account for different cores shape and boundary conditions. The effect of fluid viscosity on the rate of oil production and final oil recovery as well as the development of viscosity term in the scaling equation are reported. The commonly used methods to quantitatively evaluate the wettability of cores and the SI under mix-and oil-wet conditions are introduced. And last but not least, the methods and mechanism of wettability alteration for enhanced oil recovery in mix-or oil-wet fractured reservoirs are presented.Keywords: Spontaneous imbibition, fractured reservoirs, boundary condition, viscosity ratio, wettability.Citation: Meng, Q., Liu, H., Wang, J.

“…Furthermore, the alkyl chain tails of the organic compounds adsorbed parallel to the surface at the interface. Besides, this orientation of the alkyl chains might be contributed to inhibit the interactions between the chains of the organic compounds and reduce the hydrophobic interactions at this region 37,38 . From the experimental data it can be observed that, the adsorptive amounts of the studied organic cations onto Amberlite IR 120 H + resin decreased with increasing the alkyl chain length at low adsorbate concentrations due to the diminution of the electrostatic attractive forces between the studied organic cations and the adsorbent surface.…”

“…For this reason any further adsorption in this stage was a result of the hydrophobic interaction that was controlled by van der Waals forces. Certainly, as the adsorbate amount increased in solutions, the adsorbent surface became hydrophobic due to the orientation of the alkyl chains perpendicular towards the bulk solution 37,38 . The increase of hydrophobicity on the surface made the system unstable due to increase the system energy.…”

The effect of Amberlite-IR 120 H + resin to remove some organic compounds (N-alkyl pyridinium salts) from aqueous solutions at certain conditions was investigated. The effect of resin dosage, contact time, adsorbate concentration, ionic strength and solution temperature on the adsorption efficiency was examined. The experimental data collected generally proved that the adsorption efficiency decreased as the alkyl chain increased. The thermodynamic equilibrium parameters of the adsorption processes were evaluated and showed that the adsorption process is spontaneous, disordered and exothermic. Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D.R) isotherm models were applied based on the batch method. Freundlich, Temkin and D. R gave bilinear segments model based on the adsorbate initial concentrations except that for compound III where it gave straight of one segment for Temkin adsorption isotherm. Overall, Amberlite-IR 120 H + resin is effective in removing some N-alkyl pyridinium salts from an aqueous solution.
