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.

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 ...

Spontaneous imbibition characteristics of diatomite
Journal of Petroleum Science and Engineering, 2000 A systematic investigation of fluid flow characteristics within diatomite (a high porosity, low permeability, siliceous rock) is reported. Using an X-ray computerized tomography (CT) scanner, and a novel, CT-compatible imbibition cell, we study ...

Onset of Spontaneous Imbibition [PDF]
, 2017 The spontaneous imbibition process in porous media is an important recovery mechanism and is governed by capillary forces that arise when two immiscible fluids are present in the pore space.

Spontaneous imbibition of liquids into nanopores
MRS Proceedings, 2005 We present measurements on the spontaneous imbibition of water, a linear hydrocarbon (n-C15H34) and a liquid crystal (8OCB) into the pore space of monolithic, nanoporous Vycor glass (mean pore radius 5nm). Measurements of the mass uptake as a function of

Spontaneous Imbibition Experiment and Main Influence Factors in Ultra-Low-Permeability Reservoirs
Geofluids, 2023 The imbibition has an important influence on the water injection development of ultra-low-permeability reservoirs. In this paper, the nuclear magnetic resonance (NMR) high-temperature and high-pressure displacement system was used to simulate the ...
