... energy carrier in this regard. Underground hydrogen storage (UHS) presents significant potential but requires a thorough understanding of H 2 behavior in porous media. One of the crucial parameters is interfacial tension (IFT) which influences capillary entry pressure, H 2 column height, and storage...

... the compatibility problem in high temperature and high salinity reservoirs. This study optimized some surfactant additives for the nanosheet to demonstrate some synergism effects at target reservoir conditions. Nanosheet/surfactant candidates with similar interfacial tension (IFT) performance but different...

... Abstract The interfacial tension (IFT) of aqueous CO 2 systems plays a critical role in determining CO 2 capillary entry pressure, maximum CO 2 storage height, and subsurface storage capacity. Conventional methods for measuring IFT are time-consuming and resource-intensive. This study...

... tension (IFT), wetting ability, and spontaneous imbibition in limestone samples. The thermal stability and salinity tolerance was correlated with the molecular structure of AECs. IFT on the boundary with n-decane and crude oil was evaluated with the spinning drop tensiometry method at five temperatures...

... parameter is the interfacial tension (IFT) of the fluid-fluid system in question e.g., CO 2 -brine IFT for CO 2 geo-storage. Importantly, the IFT influences the capillary pressure of the seal, which, in turn, controls fluid leakage. In addition, different fluid-fluid IFTs give rise to distinct relative...

... as a potential replacement for ILs due to their non-toxic nature, biodegradable, non-flammable nature, and cost. In this study, the effectiveness of DES is investigated by observing its ability to change Interfacial tension (IFT). The studies included the effects of pressure, temperature, salinity...

... Abstract Interfacial tension (IFT) reduction, emulsification, and wettability alteration are three main mechanisms for surfactant flooding. In traditional concepts, researchers often connect low IFT with strong emulsifying ability and use microemulsion phase behavior test to choose surfactant...

... Abstract It is a well-known EOR mechanism that residual oil in swept zone after water flooding (including oil drops, films and clusters) can be mobilized by low interfacial tension (IFT) during surfactant flooding. The aim of this work is to investigate if trapped oil in low-permeability zone...

... emulsions. Furthermore, it is clear that surfactants contribute to the stability of nanoparticles and emulsions in order to reduce IFT and change the rock wettability toward water. The main objective of this study is to investigate the effects of nano particles and surfactant on interfacial tention, fluid...
