Effects of fracturing fluid composition and other factors on improving the oil imbibition recovery of shale reservoir [PDF]
, 2023 Imbibition is an important mechanism of shale reservoir development. In exploring the factors affecting the enhanced recovery of shale reservoirs by imbibition, laboratory spontaneous and forced imbibition experiments were conducted using outcrop cores ...

Avalanche dynamics in fluid imbibition near the depinning transition [PDF]
Physical Review E, 2009 We study avalanche dynamics and local activity of forced-flow imbibition fronts in disordered media. We focus on the front dynamics as the mean velocity $\bar{v}$ of the interface is decreased and the pinning state is approached. Scaling arguments allow us to obtain the statistics of avalanche sizes and durations, which become power-law distributed due

Water imbibition and water sealing in water-driven gas reservoirs development
Energy Exploration & Exploitation, 2023 To improve the poor understanding of the mechanism of spontaneous water imbibition in water invasion in gas reservoirs and overcome the difficulty in quantifying imbibed water and its impact on reservoir development, a study is carried out based on ...

Energies, 2020 In shale gas formations, imbibition is significant since the tight pore structure causes a strong capillary suction pressure. After hydraulic fracturing, imbibition during the period of shut-in affects the water recovery of flowback.

Validating mechanistic models of fluid displacement during imbibition
Advances in Water Resources, 2023 Pore-scale modelling is an important tool to improve our understanding of multiphase flow in porous media. Slow fluid invasion is commonly modelled using quasi-static pore network models (PNM). These models simulate the invasion in a network of simplified pores and throats by invading network elements in order of the quasi-static “invasion” capillary ...

Microscopic imbibition characterization of sandstone reservoirs and theoretical model optimization
Scientific Reports, 2021 Traditional porous media imbibition models deviate from the actual imbibition process in oil and gas reservoirs. Experimental studies on gas–water imbibition in reservoirs were carried out to describe the dynamic profile variation process of wet phase ...
