Evaluation of Fracturing Fluid Imbibition and Water Blocking Behavior in Unconventional Reservoir

SSRN Electronic Journal, 2022
Imbibition is believed to be beneficial to the production. However, the load recovery is low, and water blocking can have a marked impact on the production This study aims to evaluate imbibition and water blocking behavior in tight reservoir, and reveal the impact of micro pore structure on imbibition and water blocking.

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

Youqicang 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 underlying mechanisms at play in shale oil reservoirs.

A Critical Review of Osmosis-Associated Imbibition in Unconventional Formations

Energies, 2021
In petroleum engineering, imbibition is one of the most important elements for the hydraulic fracturing and water flooding processes, when extraneous fluids are introduced to the reservoir.

Study on the Imbibition Characteristics of Different Types of Pore-Throat Based on Nuclear Magnetic Resonance Technology

Geofluids, 2022
“Fracturing network+imbibition oil production” is a new attempt to effectively develop low-permeability tight reservoirs. Fracturing fluid is not only a carrier for sand carrying but also a tool in the process of imbibition.

Lattice Boltzmann modeling of the coupled imbibition-flowback behavior in a 3D shale pore structure under reservoir condition

Frontiers in Earth Science, 2023
Imbibition and flowback of fracturing fluid usually occur in the shale matrix after hydraulic fracturing, which significantly impacts shale gas production and environmental protection. The rocks of deep shale gas reservoirs are under high-temperature and

Fracturing fluid imbibition impact on gas-water two phase flow in shale fracture-matrix system

Natural Gas Industry B, 2023
A large amount of fracturing fluid in hydraulic fracturing is imbibed into the shale fracture/matrix, which leads to significant uncertainty in gas recovery evaluation. The mechanism of imbibition impact on the gas–water flow is not well understood.

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

Geofluids, 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.

Spontaneous imbibition in igneous rocks: effect of KCl concentration, confining pressure, and imbibition direction

Journal of Petroleum Exploration and Production Technology, 2020
Understanding spontaneous imbibition helps to determine the fracturing fluid volume and optimize the flowback design. At present, many studies have mainly focused on shale, but few on igneous rocks.
