... Abstract Accurate relative permeability data are essential for predicting the performance of two-phase flow through porous media. Many factors, such as the rock and fluid properties, may affect the measurement of relative permeability. However, the saturation levels of the fluids flowing...

... Abstract Adequate numerical prediction and forecasting of reservoir performance rely on the knowledge of relative permeabilities. In gravity driven processes the flow is complex, consisting of co-current and counter-current flows. This work describes the characteristics of gravity driven flow...

... Abstract The importance of relative permeability curves in calculations of reservoirperformance can hardly be overstated. Both oil-water and oil-gas two-phaserelative permeability functions are crucial parts of the input data for heavyoil reservoir simulation studies of primary depletion...

... for use with a pivoted rotor head. Introduction Two of the most important parameters required by petroleum reservoir engineers in order to calculate the performance of oil and gas reservoirs are capillary pressureand relative permeability. Unfortunately, these are he two most difficult parameters...

... by fracture permeability perpendicular to fracture planes. There is no need to provide fracture relative permeabilities in our model. Numerical simulation results are in excellent agreement with experimental data. Introduction Gravity drainage in fractured porous media is related to, 1) matrix permeability...

... Abstract Three-phase relative permeability plays an important role in the numerical simulation of oil recovery processes. Thermal methods for heavy oil recovery, such as steam drive, in-situ combustion; alternating gas and water injection; and immiscible gas injection in the presence of mobile...

The relative permeabilities used in this type of analysis are usually obtained from laboratory tests which pay...

... Abstract In surfactant flooding the form of the relative permeabilities at high capillary numbers has a crucial role in determining the transport of equilibrium phases through the reservoir. A conventional assumption is that a system which produces ultra-low interfacial tensions is close...
