“…The model proposed in this study can also be used as a tool in the designing and planning of LSWF projects to give a forecast of the oil recovery when the LSWF is implemented. It should be noted that the current study is an extension of our previous work where the WI was developed from only the ζ-potentials [75].…”

“…). We assumed site-density of 4.95/nm 2 for each of the calcite lattice ions, consistent with literature [75,81,82]. Specific surface area of oil and calcite was set to 1 m 2 /g based on Korrani & Jerauld [72], Brady et al [55], and Bonto et al [71].…”

“…It should be noted that two capacitance values are required in TLM: C1 (capacitance between the 0-plane and the inner Helmholtz plane) and C2 (capacitance between the inner Helmholtz plane and the outer Helmholtz plane), and following other investigators [70,71,83,84], we used C1 = 2.8F/m 2 and C2 = 4.5F/m 2 . The detailed description of the TLM can be found elsewhere [75].…”

“…The electric surfaces vary with ionic strength, pH, and ionic composition, and cannot be explained by simple adsorption models . Thus, surface complexation models (SCMs) are applied in modeling the chemical interactions that accompany smart water injection into crude oil reservoirs and the electrical potential that develops between a charged surface and aqueous solutions. − SCM takes into consideration both adsorption onto surfaces and the electric double-layer (EDL) which is lacking in simple adsorption models. , …”

This study presents the interfacial dynamics of viscoelastic thin electrolyte films between crude oil and rock surface, by integrating the effects of salt type and concentrations into the nonlinear evolution equation for viscoelastic thin liquid films. Dimensionless interfacial tension (IFT) is calculated for crude oil− NaCl, Na 2 SO 4 , MgCl 2 , MgSO 4 , CaCl 2 , and CaSO 4 interfaces. Subsequently, the interfacial dynamics of the electrolyte films (bulk phase) are evaluated at selected characteristic viscoelastic parameters and various exposure times. Results show that chloride salts of Na + , Mg 2+ , and Ca 2+ have lesser deteriorating effects on thin-film integrity compared with sulfate salts of the same cations while the presence of 1000 ppm MgCl 2 proves to constitute the least barrier to the stability of thin films. Contact angle is the most critical parameter affecting film dynamics, followed by crude oil−brine interfacial tension and the viscosity of thin electrolyte films. The difference between the ζ-potentials calculated at the crude oil−brine interface and at the brine−rock interface is a major factor in determining the response of thin electrolyte films to perturbations. A large difference between the two values of ζ-potential at the interfaces leads to better resistance to perturbations. Evaluation of the interfacial dynamics of viscoelastic thin electrolyte films is, therefore, a reliable method to determine wettability alteration due to smart water effects.
