Abstract Relative permeability is a primary parameter for determining the reservoir behaviour of coal seams. We present numerous relative permeability curves measured in the laboratory as well as curves from numerically matching field performance.

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 Capillary Pressure
SPE Annual Technical Conference and Exhibition, 2002Abstract 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 from Centrifuge Data
SPE California Regional Meeting, 1986ABSTRACT 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.

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.

Relative Permeability of Coal: A Review
Transport in Porous Media, 2014Coalbed 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
1992Abstract 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.

Laboratory Determination of Relative Permeability
Journal of Petroleum Technology, 1952Abstract 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 ...
