Relative Permeability from Capillary Pressure

SPE Annual Technical Conference and Exhibition, 2002
Abstract A new theory is reviewed for single-component, two-phase flow in porous media. It includes wettability and capillary pressure as integral parts of the thermodynamic description and does not make use of the relative permeability concept.

Relative Permeability Studies

Journal of Petroleum Technology, 1951
Abstract Relative wetting phase permeabilities calculated from capillarypressure-saturation data are compared with measured relative permeability data.The equation relating relative permeability to capillary pressure-saturationdata is derived by assuming that a porous medium is analogous to a bundle ofcapillary ...

Relative Permeability from Centrifuge Data

SPE California Regional Meeting, 1986
ABSTRACT The drainage of a wetting phase (say oil) by a non-wetting phase (say gas) may be simulated in the centrifuge by two liquids. Such experiments were conducted on a number of cores and they are discussed in a companion paper. In this paper we consider two of the cores with available capillary pressure data.

Relative Permeability of Coal: A Review

Transport in Porous Media, 2014
Coalbed methane (CBM), once a hazard to the undermining safety, is becoming an important addition to the global energy supply. Injecting carbon dioxide \((\hbox {CO}_{2})\) into coal seams not only aids to enhance CBM production but also offers an option of \(\hbox {CO}_{2}\) sequestration helpful for the reduction of greenhouse gas release.

Chapter 7 Permeability and Relative Permeability in Rocks

1992
Abstract Important features of the topology of the pore space of rocks can be usefully quantified by analyzing digitized images of rock cross-sections. One approach computes statistical correlation functions using modern image-processing techniques.

Effect of Viscosity on Relative Permeability

Society of Petroleum Engineers Journal, 1961
Introduction 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.

Chapter 8 Permeability and Relative Permeability of Carbonate Reservoirs

1992
Publisher Summary This chapter discusses permeability and relative permeability of carbonate reservoirs. The effective permeability of a porous medium to a fluid is a measure of the ability of the medium to transmit this fluid at the existing saturation, which is usually less than 100%.

Relative-Permeability Measurements: An Overview

Journal of Petroleum Technology, 1988
Introduction Fluid transport through reservoir rocks is complex and cannot be described by theory alone. Darcy's law, an empirical equation describing the laminar flow of incompressible fluids, is largely used for calculation of fluid flow through porous media.

Laboratory Determination of Relative Permeability

Journal of Petroleum Technology, 1952
Abstract A detailed study of a number of methods of relative permeability measurementhas been made in a search for the technique most suited to routine analysis ofcores taken from reservoir rock. It has been found from tests run on the samesamples of core material by a number of techniques that the Penn State ...
