Insights, Trends and Challenges Associated with Measuring Coal Relative Permeability [PDF]

E3S Web of Conferences, 2019
Due to the poroelasticity of coal, both porosity and permeability change over the life of the field as pore pressure decreases and effective stress increases.

Stress dependent gas-water relative permeability in gas hydrates: A theoretical model

Advances in Geo-Energy Research, 2020
Research activities are currently being conducted to study multiphase flow in hydrate-bearing sediments (HBS). In this study, in view of the assumption that hydrates are evenly distributed in HBS with two major hydrate-growth patterns, i.e., pore filling

Three-Phase Relative Permeability [PDF]

Journal of Petroleum Technology, 1956
Abstract The results of three-phase relative permeability tests on nine water-wet consolidated Berea sandstone samples are presented as composite ternary diagrams showing isoperms of oil, water and gas. Capillary pressure control was exercised over the flow of gas and oil in the presence of water.

Gyrotropic impact upon negatively refracting surfaces [PDF]

, 2005
Surface wave propagation at the interface between different types of gyrotropic materials and an isotropic negatively refracting medium, in which the relative permittivity and relative permeability are, simultaneously, negative is investigated. A general

Experimental Study on Gas–Water Relative Permeability Characteristics of Tight Sandstone Reservoir in Ordos Basin

Geofluids, 2022
Accurate measurement of relative permeability curve is the basis for evaluating gas reservoir performance. The unsteady-state method could bring significant measurement error for low-permeability cores.
