Study of the Influence of Dynamic and Static Capillary Forces on Production in Low-Permeability Reservoirs [PDF]

open access: goldEnergies, 2023
Low-permeability reservoirs have strong heterogeneity, and the production prediction based on traditional seepage model is not accurate enough. The dynamic capillary-force seepage model can characterize the dynamic heterogeneity of seepage and more ...

High accuracy capillary network representation in digital rock reveals permeability scaling functions [PDF]

open access: goldScientific Reports, 2021
Permeability is the key parameter for quantifying fluid flow in porous rocks. Knowledge of the spatial distribution of the connected pore space allows, in principle, to predict the permeability of a rock sample. However, limitations in feature resolution

Permeability of Single‐Layer‐Free‐Standing Meshes at Varying Capillary Pressure via a Novel Method

open access: yesAdvanced Materials Interfaces, 2023
The permeability of mesh wicks is important for various applications, including two‐phase heat transfer. However, the understanding of the permeability of single‐layer, free‐standing mesh wicks, with liquid–gas interfaces on both sides, is limited.
