Coupling effect of critical properties shift and capillary pressure on confined fluids: A simulation study in tight reservoirs. [PDF]

open access: yesHeliyon, 2023
Critical properties shift and large capillary pressure are important contributors for the phase behavior altering of nanopore fluid. However, the effects of critical properties shift and large capillary pressure on the phase behavior are ignored in ...

A Prediction Model of the Capillary Pressure J-Function. [PDF]

open access: yesPLoS One, 2016
The capillary pressure J-function is a dimensionless measure of the capillary pressure of a fluid in a porous medium. The function was derived based on a capillary bundle model.

Preventing plastic shrinkage cracking by monitoring the capillary pressure build-up in self-compacting concrete [PDF]

open access: yesMATEC Web of Conferences, 2022
Plastic shrinkage cracking is a problem for the service life, aesthetics and durability of concrete members. It occurs when tensile stresses are induced in fresh concrete, through plastic shrinkage that is restrained.

Prediction of centrifuge capillary pressure using machine learning techniques [PDF]

open access: yesE3S Web of Conferences, 2023
In current literature in the petroleum industry, machine learning has been used to predict capillary pressure only on the centrifugal data points and not the complete capillary pressure curves generated from existing correlations after analysis.

A new methodology for grouping and averaging capillary pressure curves for reservoir models

open access: yesEnergy Geoscience, 2021
Primary drainage capillary pressure data are usually correlatable with a 3D predictable property of grid cells. Accordingly, rock typing is normally performed based on an established correlation.
