... usually added in OBM formulations. We investigated the effect of different surfactant concentrations on the fluid-fluid interfacial tension (IFT) properties and on the fluid-solid interaction properties, using contact angle measurements on both sandstone and carbonate model surfaces. Furthermore, we...

... was used in the 2 nd step for comparison of three different brine-surfactant solutions (BSS). The BSS with lowest IFT was then used to study the IFT behavior of three different oils with CO 2 . Last step consists of contact angle(CA) measurements of oil with dolomite rock in the presence of CO 2 and BSS...

... compared to the short chain (heptanoic acid) as confirmed by the measured contact angles. Twice dilution of Arabian Gulf seawater has been found to be a less effecient EOR fluid for wettability alteration as compared to undiluted Arabian Gulf seawater. This was confirmed by the changes in the measured...
