Fluid topology, pore size and aspect ratio during imbibition
Transport in Porous Media, 1988Imbibition in glass micromodels for air-mercury and water-oil systems occurs by wetting phase (wp) cluster growth and frontal drive processes. Lower capillary number and higher wetting phase (wp) saturation at the start of imbibition favour cluster growth.

The forced imbibition model for fracturing fluid into gas shales
Journal of Petroleum Science and Engineering, 2019Abstract 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.

Imbibition-Dominated Matrix-Fracture Fluid Transfer in Dual Porosity Simulators
Proceedings of SPE Annual Technical Conference and Exhibition, 1987ABSTRACT Published imbibition experiments of an advancing fracture water level surrounding a single matrix block are simulated using a fine grid single porosity model and various double porosity models. The fine grid simulations show that a stationary water saturation profile quickly develops and advances in the matrix at the same rate ...

Microscopic mechanism of fracturing fluid imbibition in stimulated tight oil reservoir
Journal of Petroleum Science and Engineering, 2021Abstract The imbibition of fracturing fluid is of great significance to improve the development of fractured tight oil reservoirs. Understanding the micro-characteristics of fracturing fluid imbibition is necessary to improve the imbibition efficiency.

Expansion and shrinkage of sandstones during spontaneous imbibition of fluids
Environmental Earth Sciences, 2018The 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 ...

An Analytical Model for Fluid Imbibition in Organic Nanopores
Transport in Porous Media, 2019Estimating 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 ...

Avalanches, Non-Gaussian Fluctuations and Intermittency in Fluid Imbibition
2016We review our work on the invasion of a model open fracture by a viscous wetting fluid , in the context of research on the spatiotemporal dynamics of fronts in disordered media . The model consists on a Hele-Shaw cell with randomly-distributed dichotomic variations of gap thickness.

Fluid saturation evolution with imbibition in unconventional natural gas reservoirs
Interpretation, 2018Hydraulic fracturing plays an important role in developing unconventional natural gas. The large amount of fracturing fluid retention becomes a significant phenomenon in gas fields. Much research has been carried out to explain this mechanism. Imbibition is regarded as one of the important factors and has been investigated extensively.

Saturation Modelling Under Complex Fluid Fill History - Drainage and Imbibition
Abu Dhabi International Petroleum Exhibition & Conference, 2017Abstract A saturation modelling approach is presented for fields and reservoirs under complex hydrocarbon charging history. The model resolves saturation-height functions for the primary drainage, imbibition and secondary drainage equilibriums.

Optically observed imbibition and drainage of wetting fluid in nanoporous Vycor glass
Journal of the Optical Society of America A, 2015The 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 ...
