The Spontaneous Imbibition of Micro/Nano Structures in Tight Matrix and the Influence on Imbibition Potential [PDF]

Micromachines, 2020
Tight matrix has relatively low permeability and porosity, with abundant micro/nano pores. The capillary force in these pores are relatively strong, making the wetting liquid easier to be imbibed in the matrix.

Spontaneous Imbibition and Evaporation in Rocks at the Nanometer Scale. [PDF]

Energy Fuels, 2023
Understanding multiphase fluid displacement dynamics in porous media is of great importance in efficiently designing hydrogen storage projects in porous reservoirs. During gas injection and extraction, cyclic evaporation and spontaneous imbibition processes have an impact on storage efficiency. In both imbibition and evaporation, capillary films on the

Lattice Boltzmann Modeling of Spontaneous Imbibition in Variable-Diameter Capillaries

Energies, 2022
Previous micro-scale studies of the effect of pore structure on spontaneous imbibition are mainly limited to invariable-diameter capillaries. However, in real oil and gas reservoir formations, the capillary diameters are changing and interconnected ...

Poromechanical controls on spontaneous imbibition in earth materials. [PDF]

Sci Rep, 2021
AbstractOver the last century, the state of stress in the earth’s upper crust has undergone rapid changes because of human activities associated with fluid withdrawal and injection in subsurface formations. The stress dependency of multiphase flow mechanisms in earth materials is a substantial challenge to understand, quantify, and model for many ...

Study on mechanism of spontaneous imbibition and pressurized imbibition in shale oil reservoirs [PDF]

Journal of Petroleum Exploration and Production, 2020
AbstractImbibition is one of the important methods of oil recovery in shale oil reservoirs. At present, more in-depth studies have been carried out on the fracture system and matrix system, and there are few studies on the effect of energy enhancement on imbibition in shale oil reservoirs.

A Comprehensive Methodology for Investigating Cocurrent Spontaneous Imbibition in Coal. [PDF]

ACS Omega
Visualizing and quantifying fluid distribution during spontaneous imbibition at the nanomicro scale is vital for understanding microfluid flow and dynamic wettability in coalbed methane (CBM) reservoirs, which could serve as a fundamental basis for optimizing the parameters of the hydraulic fracturing process. In this study, fluid distribution and flow

Experimental study of water imbibition characteristics of the lacustrine shale in Sichuan Basin

Petroleum, 2023
Through the stimulation method of large-scale hydraulic fracturing, the spontaneous imbibition capacity of the water phase in the shale reservoir has great influence on the effect of stimulation. Generally, the lacustrine shale has the characteristics of

Interface pinning in spontaneous imbibition [PDF]

Physical Review E, 2001
Evaporation and gravity induced pinning in spontaneous imbibition are examined within a phase field formalism. Evaporation is introduced via a nonconserving term and gravity through a convective term that constrains the influx of liquid. Their effects are described by dimensionless coupling constants epsilon and g, respectively.
