DOI: 10.1002/mrc.4563
Abstract: Counter‐current imbibition is a process whereby a wetting phase spontaneously imbibes into a porous media, displacing the non‐wetting phase. This process is considered an important oil recovery mechanism during water flooding in fractured oil reservoirs.… read more here.

DOI: 10.1007/s11242-019-01358-z
Abstract: 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… read more here.

DOI: 10.1007/s13202-020-00997-z
Abstract: 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. As such, in this study, imbibition… read more here.
