Analyzing Single- and Two-parameter Models for Describing Oil Recovery in Imbibition from Fractured Reservoirs [PDF]
Iranian Journal of Oil & Gas Science and Technology, 2020 The imbibition process is known as one of the main production mechanisms in fractured reservoirs where oil/gas-filled matrix blocks are surrounded by water-filled fractures.

Fluid imbibition into PMETAC functionalized mesoporous films [PDF]
Colloids and Surfaces A: Physicochemical and Engineering AspectsFluid imbibition into nanoporous films is of relevance in water harvesting, separation, or sensing. Furthermore, grafting polymers from the mesopore walls affects the wettability and ionic accessibility of mesoporous films. Using poly[2-(methacryloyloxy)ethyltrimethylammonium chloride] (PMETAC) functionalized mesoporous films we observe that the ...

Yield stress fluids solidifying in capillary imbibition
Journal of Fluid MechanicsWhen subjected to external stress exceeding their yield stress ( $\sigma _{Y}$ ), yield stress fluids (YSFs) undergo transition from solid to liquid. While the flow dynamics of capillary flows – including wetting, coating, spreading, and wicking – can be predicted accurately for fluids without yield stress, only a few ...

Avalanches in strong imbibition
Communications Physics, 2022 Drainage and imbibition in porous media are two opposite fluid displacement scenarios with remarkably different underlying mechanisms. Here, the authors demonstrate that strong imbibition in porous media shows features of self-organized criticality ...
