An Experimental Study of the Influence of Interfacial Tension on Water–Oil Two-Phase Relative Permeability
Adding surfactant into the displacing aqueous phase during surfactant-enhanced aquifer remediation of NAPL contamination and in chemical flooding oil recovery significantly changes interfacial tension (IFT) (σ) on water–oil interfaces within porous media. The change in IFT may have a large impact on relative permeability for the two-phase flow system. In most subsurface flow investigations, how...
متن کاملThe Influence of Interfacial Tension on Water/Oil Two-Phase Relative Permeability
Water-oil relative permeability characterizes two-phase flow and displacement processes, and its functional form is difficult to determine in a particular reservoir study. Adding various chemical agents into the displacing aqueous phase during alkaline-surfactant-polymer combination chemical flooding in oil production significantly changes interfacial tension (σ) on water-oil interfaces, and al...
متن کاملA Novel Approach to Measuring Water and Oil Relative Permeabilities in Two-phase Fluid Flow in Porous Media
In this study, direct laboratory measurements of unsteady-state imbibition test are used in a new approach to obtain relative permeability curves with no predetermined functionality assumptions. Four equations of continuity, Darcy’s law, cumulative oil production, and water fractional flow are employed in combination together under certain assumptions to present the new approach which interpret...
متن کاملImproving Water-oil Relative Permeability Parameters Using New Synthesized Calcium Oxide and Commercial Silica Nanofluids
This paper addressed the application of new hydrophobic synthesized calcium oxide (CaO) and silicon dioxide (SiO2) nanofluids to low permeability carbonate porous media. Crude oil and plugs were selected from one of oil reservoirs in the west of Iran. The main goal of this paper is comparing the results of improving water-oil relative permeability parameters in low permeability plugs...
متن کاملEngineered Depressurisation of Waterflooded Reservoirs: Representative Relative Permeability Measurements
This paper describes a determination of critical gas saturations and relative permeabilities relevant to the depressurisation of two North Sea fields. A series of reservoir condition coreflood experiments and associated numerical simulations is described. Four experiments were conducted with aged cores and fluids and each comprised of a waterflood, followed by depressurisation at different rate...
