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.

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.

Application of Artificial Neural Networks for Predicting Relative Permeability in Talang Akar Formation [PDF]

E3S Web of Conferences
Relative permeability is a substantial parameter for estimating multi-phase fluid flow in porous rocks. It is a complex physical property that is influenced by the behavior and interactions between the fluid and rock phases.

Relative Permeabilities of Homogeneous and Heterogeneous Laminated Rock Samples under Hydrostatic and Triaxial Stresses

Journal of King Saud University: Engineering Sciences, 2010
Production performance of a hydrocarbon-bearing reservoir is vital and largely controlled by certain reservoir rock and fluids intrinsic properties. Therefore, realistic measurements of reservoir rock properties under simulated in-situ stress-state are ...

Mechanisms of IgE‐mediated food allergy and the role of allergen‐specific B cells

FEBS Letters, EarlyView.
Food allergy arises when allergen‐specific B cells preferentially produce immunoglobulin E (IgE) antibodies against harmless foods. This article explains the mechanisms driving IgE‐mediated reactions, highlights the central role of these B cells, and discusses how natural tolerance (NT) and oral immunotherapy (OIT) can reshape allergic immune responses.
