Four sets of experiments were conducted to study the effect of injection pressure, interfacial tension, wettability, and fluid rheology on sweep efficiency and load recovery. Glass beads...

...Effects of Nitrogen in the Gas Phase Abstract This paper presents preliminary results from a laboratory study designed to measure gas-water interfacial tension (IFT) at high-pressure/high-temperature (HP/HT) reservoir conditions. We used a pendant drop method with computer-aided image...

Accurate determination of fluid properties and interfacial tensions at reservoir conditions is essential to the optimisation of the depletion strategy and is strongly...

... For very low values of interfacial tension, though, especially close to the critical point, prediction is more tricky, since there are great changes in the relative permeabilities for small changes in interfacial tension. For values of σ=0.001 mN/m, the relative permeabilities can be represented...
