“… where σ i and ψ i represent the charge density (C/m 2 ) and the potential (mV), respectively, at plane i . The potential at the 0-plane (ψ o ) and 2-plane (ψ 2 ) corresponds to the surface potential and the ζ-potential based on the similar assumption by Takeya et al ,, For the calcite–brine interface, C 1 and C 2 were assumed to be 1.3 and 4.5 F/m 2 , respectively. , C 1 and C 2 of 3.1 and 2.25 F/m 2 , respectively, were assumed for the oil–brine interface similar to the approach adopted by Takeya et al Vinogradov et al developed a relationship that showed the dependence of the capacitance value to the ionic strength of the brine used. In this work, since the ionic strengths of the brines used were in the range of seawater (∼1.1 M), it was justifiable to use a constant capacitance for the calculations.…”

Ionic Interactions at the Crude Oil–Brine–Rock Interfaces Using Different Surface Complexation Models and DLVO Theory: Application to Carbonate Wettability

The impact of ionic association with the carbonate surface and its influence toward carbonate wettability remains unclear and is an important topic of interest in the current literature. In this work, a triple layer model (TLM) approach was used to capture the electrokinetic interactions at both calcite–brine and oil–brine interfaces. The developed TLM was assembled against measured ζ-potential values from the literature, successfully capturing the trends and closely matching the ζ-potential magnitudes. The developed TLM was compared to a diffused layer model (DLM) presented in previous works, with the DLM showing a better match to the ζ-potential values for seawater brine solutions. The ζ-potential values predicted from both surface complexation models (SCMs) were used to calculate the total interaction energy (or potential) based on the Derjaguin, Landau, Verwey, and Overbeek (DLVO) theory. It was observed that low Mg 2+ and high SO 4 2– concentrations in modified composition brine (MCB) made the calcite–brine interface more negative. However, at the oil–brine interface, low Mg 2+ made the oil–brine interface more negative but high SO 4 2– concentrations slightly shifted the oil–brine ζ-potential toward negative. At the crude oil–brine–rock (COBR) interfaces, low Mg 2+ and high SO 4 2– concentrations in the MCB were observed to generate a greater repulsive interaction energy, which could trigger carbonate wettability alteration toward water wetness. The absolute sum of the ζ-potential at both interfaces was observed to be correlated to the total interaction potential at a 0.25 nm separating distance. Thus, an increase in the absolute sum of the ζ-potentials would generate a greater repulsive interaction potential and trigger wettability alteration. Therefore, these SCMs can be applied to design modified composition brine capable of triggering a repulsive interaction energy to alter carbonate wettability toward water wetness.

“…For instance, previous publications have reported a correlation between the surface speciation and electrokinetic potential at the oil/brine and rock/brine interfaces and the residual oil saturation from spontaneous imbibition tests on chalk and the contact angle of calcite . Others have shown that contact angles can be estimated based on the DLVO (Derjaguin–Landau–Verwey–Overbeek) extended theory. However, none of these approaches considers an explicit interaction between the crude oil components and the calcite, which makes it impossible to quantify the polar components adsorbed on the mineral, which eventually governs the wettability condition.…”

The adsorption of polar organic molecules on the surface of brine-saturated carbonate rocks alters the relative mobility of oil and water with important implications for oil production and groundwater remediation. We propose a mathematical model for the adsorption of polar organic acid groups (initially contained in an oil phase) on calcite in the presence of brine. We reduce the problem into smaller subsystems and characterize them by identifying the key interactions. Oil–brine equilibrium is dictated by the partitioning of acidic components between the two phases. The dissolved acids ionize to carboxylate species in the water phase, which may either form complexes with the calcite surface or precipitate as calcium carboxylate salts by binding calcium ions from the solution. All these interactions are implemented into a Phreeqc model as equilibrium and kinetic processes. To obtain the main parameters (e.g., partition, ionization, or adsorption constants) governing the behavior of the different subsystems at different chemical conditions, we tune the sub-models to relevant experimental data (e.g., partitioning, precipitation, adsorption, and electrokinetic measurements). We then assess the performance of the model by coupling the reaction network to the transport equations and simulating the crude oil injection within a chalk core to predict effluent acid concentration history. By defining the total acidity of crude oil as a mixture of several carboxylic acids, our model satisfactorily fits the experimental data. The total acid number that is commonly reported as the sole indicator for the concentration of organic acids in oil does not allow distinguishing between different types of organic acids nor their affinity toward the calcite surface. More sophisticated analytical methods for quantifying the acid species in the crude oil are required for a more accurate description of the adsorption process using our model.
