Effect of Viscosity on Relative Permeability
Society of Petroleum Engineers Journal, 1961Introduction The general application of Darcy's law to natural rocks has already been challenged in the literature. The evidence shows that the permeability as calculated from the Darcy equation can be a function of the pressure drop and the salt concentration of the water phase.

Laboratory Measurements of Relative Permeability
Journal of Petroleum Technology, 1951Abstract This paper presents the results of laboratory measurements of relativepermeabilities to oil and gas on small core samples of reservoir rock by fivemethods, and describes the influences of such factors as boundary effect, hysteresis, and rate upon these measurements. The five methods used were the"Penn State,

Relative Permeability From Thermodynamics
SPE Journal, 2004Summary A new theory is reviewed for single-component, two-phase flow in porous media. It integrates thermodynamics with fluid mechanics and includes wettability in the thermodynamic description. It does not make use of the relative permeability concept.

Chapter 4 Relative Permeabilities
1985Publisher Summary Production from petroleum reservoirs under primary, secondary, or tertiary processes usually involves the simultaneous flow of two or more fluids. Multiphase flow of fluids through porous media can be related to a relative permeability of each phase, fluid viscosities, pressure drop, capillary pressure, and permeability.

Issues with Gas Relative Permeability in Low-permeability Sandstones
2008A review of gas relative permeability (krg) studies of low-permeability sandstones indicates that they can be modeled using the Corey equation, but scarce data near the critical gas saturation (Sgc) limit krg modeling at high water saturations. Confined mercury injection capillary pressure and coupled electrical resistance measurements on Mesaverde ...
