A fractal permeability model for the dual-porosity media of tight gas reservoirs

open access: yesEnergy Exploration & Exploitation, 2021
Hydraulic fracturing is a crucial method for the exploitation of tight gas reservoirs. The matrix permeability is a key factor influencing the fracturing result. This paper assumes that the matrix permeability is provided by a series of capillary bundles

When Capillary Permeability Increases

open access: yes, 1987
Capillary permeability is usually ascribed to a number of "small" pores. In this article the small-pore pathway is identified as interruptions in the tight junctions between endothelial cells.

Co-estimation of saturation functions (k r and P c) from unsteady-state core-flood experiment in tight carbonate rocks

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
The production from oil and gas reservoirs is greatly affected by rock and fluid properties of the porous rock. Capillary pressure (P c) and relative permeability (k r) are two important properties employed in the mathematical simulation reservoirs for ...

Analysis of water performance of coating mortars incorporated with tire rubber

open access: yesRevista Ingeniería de Construcción, 2022
This paper analyzed the behavior of mixed mortars incorporated with rubber from the tire retreading process, based on partial sand substitution. The content of rubber incorporation in the mortars was 5%, 10%, 15%, and 20% by volume.

Interplay Between Permeability Retardation and Capillary Trapping of Rising Carbon Dioxide in Storage Reservoirs

open access: yes, 2018
SummaryThe main objective of this work is to understand, by analytical and numerical study, how permeability retardation interacts with capillary-barrier trapping to cause accumulation as carbon dioxide (CO2) migrates upward in saline aquifers during ...

The Colloid Osmotic Pressure Across the Glycocalyx: Role of Interstitial Fluid Sub-Compartments in Trans-Vascular Fluid Exchange in Skeletal Muscle

open access: yesFrontiers in Cell and Developmental Biology, 2021
The primary purpose of these investigations is to integrate our growing knowledge about the endothelial glycocalyx as a permeability and osmotic barrier into models of trans-vascular fluid exchange in whole organs.

Influence of Capillary Pressure on Estimation of Relative Permeability for Immiscible WAG Processes [PDF]

open access: yes, 2008
Capillary pressure is one of the important parameters when describing flow in porous media. This parameter is nevertheless in some cases neglected, especially if no reliable measured data is available.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
