Interfacial Tension of Confined Hydrocarbons in Nitrogen-Functionalized Nanopores: Coupled Effects of Surface Chemistry and Confinement
Interfacial tension (IFT) in nanoscale pores governs multiphase flow, capillary trapping, and hydrocarbon recovery in unconventional reservoirs, yet how pore size and pore-wall chemistry jointly control this behavior remains poorly understood. Because the organic (kerogen) surfaces lining these pores are chemically h...
