... and fluid properties. A polymer additive was used to improve particles stability dispersed in saline water. Meanwhile, a surfactant additive was added into the formulation to observe any synergetic effect of displacing oil. The interfacial tension (IFT), optical contact angle (OCA), and relative...

... and wettability alteration of the carbonate rock, which leads to desirable oil relative-permeability behavior. Contact angle tests are the common approach for measurement of the preferential affinity of reservoir rocks to fluids. However, the laboratory methods for contact angle measurement are costly and time...

..., and the variation in crystal faces. Although the presence of clay minerals heterogeneity has been proven previously, its effect on the wettability measurements and the CO 2 storage capacity has not been studied yet. Thus, in this paper, we therefore systematically measured the contact angle (wettability) of pure...

..., contact angle, wettability, viscosity and core displacement, were conducted to investigate the effects of nanometer dispersion on the recovery of crude oil in Bohai Q oilfield. It was observed that nanometer dispersion fluid at the concentration of 0.5 wt.% can: 1) reduce the oil-water interfacial tension...

... of nanoparticles on wettability alteration. The efficiency of various formulated zirconium-oxide (ZrO 2 ) based nanofluids at different nanoparticle concentrations (0-0.05 wt. %) was assessed through contact angle measurements. Results from the experiments showed ZrO 2 nanofluid have great potentials in changing...
