Experimental and modelling study of the interfacial tension of (n-decane + carbon dioxide + water) in the three phase region

Molecular modeling of interfacial properties of the hydrogen + water + decane mixture in three-phase equilibrium

“…The presence of gases (CH 4 /CO 2 ) in the H 2 O–alkane interface causes a reduction of IFT with rising pressure. 25,37–39 This is in contrast to the reported pressure effect in two-phase systems of H 2 O + alkane, where the IFT typically increases with pressure. 44,45 Further, the IFTs of the CH 4 /CO 2 –oil interface are barely influenced by the presence of H 2 O.…”

“…25 Meanwhile, interfacial properties of three-phase fluids have also been studied extensively. [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] Among them, a few studies have focused on the characteristics of interfaces in the gas + H 2 O + oil three-phase mixtures. [33][34][35][36][37][38][39][40][41][42] Three different interfaces are involved in the gas + H 2 O + oil three-phase mixtures, namely, the gas-H 2 O, the gas-oil, and the H 2 O-oil interfaces.…”

Underground hydrogen storage: A critical assessment of fluid-fluid and fluid-rock interactions

“…However, if the solubility of gas is low, less of the injected gas will dissolve into the fluids, thus, the amount of gas trapped in the pore space increases (see refs. for three phase IFT study [38]). Therefore, understanding the solubility of hydrogen gas in the reservoir fluids (e.g., brine) in a three-phase region is an important factor that determines how much of the injected gas can be lost via dissolution into the fluids and how much will remain as a separate gas phase.…”

Methane–Water Interfacial Tension in Nanopores: A Dissipative Particle Dynamics Study

“…The interfacial tension under conventional conditions has been studied by many researchers through experiments and simulation. The most widely used experimental methods are the pendant drop method − and the Wilhelmy plate method. , However, the use of these two methods is restricted by pressure, fluid properties, the accuracy of the apparatus, etc. The pressure reported in the pendant drop method is up to 44.8 MPa, which is still far below the pressure in deep shales.…”
