Abstract
Emphasizing upon the effect of rock mineralogy, aqueous media salinity and temperature, this work addresses the adsorption characteristics of surfactant on real reservoir rocks. The experimental methodology involves mineralogy and morphology analysis of reservoir rock and thermal aging based surfactant stability studies. Surfactants were screened based on the interfacial tension reduction with reservoir crude oil. Among alternate models, Langmuir isotherm model and pseudo-second order kinetics fit well to represent pertinent surfactant adsorption characteristics. An important inference from the carried out research indicates that adsorption capacity of surfactant is strongly dependent on the mineral content of the rock in the order of illite>feldspar>montmorillonite>kaolinite. These findings provide newer insights into real time surfactant adsorption characteristics, which are often ignored in conventional approaches and methodologies.
