The forced imbibition model for fracturing fluid into gas shales

Journal of Petroleum Science and Engineering, 2019
Abstract Understanding the factors controlling the fracturing fluid leak-off due to forced imbibition during the hydraulic fracturing operations is critical for the accurate assessment of the fracturing fluid invasion depth and the extent of the formation damage in gas shales.

Anomalous imbibition of non-Newtonian fluids in porous media

Chemical Engineering Science, 2020
Abstract The imbibition of a complex fluid in porous media often exhibits anomalous behavior, which is dominated by multiple time-spatial scales. In this work, a spatiotemporal fractional imbibition model (SFIM) is proposed to capture anomalous imbibition.

Spontaneous Imbibition of Fluids in Porous Vycor

Society of Petroleum Engineers Journal, 1974
Abstract The spontaneous imbibition of alkanes and alcohols in pores of 35 radius has been studied. At a rather critical molecular size The pore volume becomes insensitive to the size of imbibing molecule. Darcy's law for transient imbibition kinetics is obeyed, fluid viscosity and surface tension are valid flow ...

Imbibition in the flow of two immiscible fluids with magnetic field

The Physics of Fluids, 1974
The physical phenomenon of imbibition due to relative wettability of flowing fluid in double phase flow through homogeneous porous media is discussed. The injected liquid is conducting while the native liquid is nonconducting, and the effect of a variable magnetic field is considered.

Solvability of problems with degeneration: Imbibition of fluid in a porous medium

Differential Equations, 2016
The author considers an initial boundary value problem with degeneration, which models the motion of immiscible fluids in porous media. A class of self-similar solutions is studied with degeneration on the movable boundary and on the entry into the porous layer.

Imbibition of Mixed-Charge Surfactant Fluids in Shale Fractures

Energy & Fuels, 2019
Hydraulic fracturing of shale reservoirs often requires millions of gallons of water, but only a fraction of the injected water returns to the surface.

Insights into the influence of fluid imbibition on dynamic mechanics of tight shale

Journal of Petroleum Science and Engineering, 2019
Abstract Fluid imbibition is a recognized strong phenomenon in tight shale that could greatly influences the dynamic failure behaviors. An experimental study was carried out to account for the influences of three typical drilling fluids (Air, Oil-based, and Water-based) on dynamic mechanics of tight shale.

An Analytical Model for Fluid Imbibition in Organic Nanopores

Transport in Porous Media, 2019
Estimating the fluid imbibition flow in natural system composed of nanopores is challenging due to the strong fluid/rock molecular scale interaction and the invalidation of the macroscopic thermodynamics treatment. We develop an analytical model for Lennard-Jones fluid imbibition into an organic nanopore considering the phase transition and fluid/rock ...

Expansion and shrinkage of sandstones during spontaneous imbibition of fluids

Environmental Earth Sciences, 2018
The expansion of pure quartz sandstones is investigated during spontaneous imbibition of fluids. The selected Fontainebleau sandstone samples cover a wide variation in their petrophysical properties (e.g., porosity, permeability, P-wave velocity, and effective pore size), and demonstrate expansion and shrinkage during spontaneous imbibition of fluids ...

Optically observed imbibition and drainage of wetting fluid in nanoporous Vycor glass

Journal of the Optical Society of America A, 2015
The light scattering and absorption of monolithic nanoporous Vycor glass during imbibition and drainage of wetting fluid such as water exhibit the following two optical hysteretic characteristics: one is the hysteretic response of the transient white turbidity in the visible (Vis) region and the other the hysteretic response of the absorbance peak in ...
