Fluid imbibition into PMETAC functionalized mesoporous films [PDF]

open access: yesColloids and Surfaces A: Physicochemical and Engineering Aspects
Fluid imbibition into nanoporous films is of relevance in water harvesting, separation, or sensing. Furthermore, grafting polymers from the mesopore walls affects the wettability and ionic accessibility of mesoporous films. Using poly[2-(methacryloyloxy)ethyltrimethylammonium chloride] (PMETAC) functionalized mesoporous films we observe that the ...

Imbibition displacement mechanism of fracturing fluid in shale oil reservoir [PDF]

open access: yesYouqicang pingjia yu kaifa
The imbibition displacement of fracturing fluid is a key technique for enhancing oil recovery in shale oil reservoirs. This paper assesses the impact of fracturing fluid wetting modifiers on the efficiency of imbibition displacement and explores the ...

Imbibition Retention in the Process of Fluid Replacement in Tight Sandstone Reservoir

open access: yesGeofluids, 2022
“Fracture network stimulation and oil-water infiltration and replacement” are recent attempts to effectively produce oil from tight reservoirs. On the one hand, the formation can be fractured by the fracturing fluid, which can carry proppant into ...

Fluid imbibition in paper fibers: Precursor front

open access: yesPhysical Review E, 2008
We employ nuclear magnetic resonance imaging to study water penetration in cylindrical blocks of unsized paper prepared under different molding pressures. From the measured kinetics of the imbibition profiles, we determine the dependence of the effective transport diffusivity upon degree of saturation of the pores by the penetrating fluid.

Experimental Study on Spontaneous Imbibition Characteristics of Fracturing Fluid at Cores from Different Layers in Fuling Shale Gas Reservoir

open access: yesGeofluids, 2021
With low porosity and low permeability, shale reservoirs cannot be mined economically without large-scale hydraulic fracturing operation. However, abundant fracturing fluid will enter the reservoirs during the process of fracture.

Forced imbibition in stratified porous media: Fluid dynamics and breakthrough saturation [PDF]

open access: yesPhysical Review Fluids, 2021
Imbibition, the displacement of a nonwetting fluid by a wetting fluid, plays a central role in diverse energy, environmental, and industrial processes. While this process is typically studied in homogeneous porous media with uniform permeabilities, in many cases, the media have multiple parallel strata of different permeabilities.

Effect of electroosmotic flow on brine imbibition in porous media [PDF]

open access: yesWater Science and Engineering, 2009
Based on Darcy's Law and the Helmholta-Smoluchowski equation, an imbibition velocity formula for the water phase with an electric field was deduced, showing that the imbibition velocity with an electric field is to various extents not only related to the

Shale Formation Damage during Fracturing Fluid Imbibition and Flowback Process Considering Adsorbed Methane

open access: yesEnergies, 2022
Hydraulic fracturing of shale gas reservoirs is characterized by large fracturing fluid consumption, long working cycle and low flowback efficiency. Huge amounts of fracturing fluid retained in shale reservoirs for a long time would definitely cause ...

Improvement and effectiveness analysis of dynamic/static imbibition experiments.

open access: yesPLoS ONE
In low-permeability fractured reservoirs, there is a generalized fluid displacement between the replacement fluid in the fracture and the matrix crude oil. This imbibition behavior plays a crucial role in the development of this type of reservoir.

Study on Pore Structure of Shale and Fluid Distribution Patterns of Surfactant-Enhanced Spontaneous Imbibition

open access: yesApplied Sciences
Spontaneous imbibition modified by surfactants is a key technology for enhancing shale oil recovery. Currently, relevant studies mainly concentrate on marine shale worldwide, while the pore–fluid coupling characteristics of widely distributed medium-TOC ...
