Effects of Clay Minerals and External Pressures on Imbibition in Shales
Energies, 2021 Imbibition is an important mechanism of recovery during waterflooding and low flow-back during fracking in shale reservoirs. Experiments were carried out to study the development of imbibition in shale samples.

A Generalized Capillary Imbibition Model for Porous Media in Tight Reservoirs
Advances in Civil Engineering, 2018 Capillary imbibition models have been widely studied in oil and gas development field over the past decades. However, the existing models applied to the tight reservoirs rarely take fluid flow resistance and apparent viscosity into account.
