Adsorption and Foamability of the Bio-PLs Surfactant for Improving Oil Recovery: Experimental Insights from Carbonate CoresArticle link copied!

Popis výsledku v původním jazyce

In recent years, surfactants as chemical-enhanced oil recovery (cEOR) agents have attracted attention to improve oil recovery from carbonate reservoirs, wherein they are able to reduce the interfacial tension (IFT) and alter the wettability. This study focuses on the application of a greenly purified surfactant from local pistachio leaves in the Kurdistan region of Iraq in EOR. The plant-sourced surfactant (bio-PLs surfactant) was fabricated using low-consumption machines and lab protocols in a sustainable and environmentally friendly way and confirmed through performing several analytical approaches (FTIR, HMNR, TGA, and DSC). EOR solutions were developed at different concentrations (500 to 3500 ppm), with 2000 ppm as the CMC based on the electrical conductivity and surface tension data. The experimental approach consists of measurements and evaluations of IFT reduction, wettability alteration, foamability, foam stability, salt tolerance, and adsorption. The obtaining results show that the bio-PLs surfactant decreased the IFT by 72.55% from 29.28 to 8.04 mN/m and altered the wettability by minimizing the contact angle (CA) from 118.4 to 84.92°. The bio-PLs surfactant exhibited a stable emulsion over 15 days with 66% as the minimum reduction and maintained stability with low-salt precipitation up to the addition of 10 wt % NaCl. Moreover, the adsorption results, measured experimentally and estimated using Langmuir, Freundlich, and Tamkin isotherms, showed a sharp increase in surfactant adsorption by increasing the surfactant concentration from 500 ppm to the CMC point of 2000 ppm that was 7.032 g/mg rock, then the increasing rate was reduced by limiting the presence of rock surface-active sites and micelle formation that remains within the bulk solution. The experimental results illustrated the best fits with the Langmuir isotherm with a R2of 0.9631, which suggests monolayer surfactant adsorption on the rock surface. These findings of saponin extracted from pistachio leaves support its applicability in green EOR processes.
