Spontaneous Imbibition in Small Cores [PDF]
Asia Pacific Oil and Gas Conference and Exhibition, 2007 Abstract This paper presents experimental data for co-current spontaneous imbibition into cores having bulk volumes from 0.1 to 12 cm3. Simple experiments of brine imbibing into air-filled cores were carried out. Homogeneous sandstone cores (Berea and Bentheim) and a carbonate core (Mt. Gambier) were used in the experiments.

Spontaneous Imbibition in Nanopores of Different Roughness and Wettability [PDF]
Langmuir, 2010 The spontaneous imbibition of liquid in nanopores of different roughness is investigated using coarse grain molecular dynamics (MD) simulation. The numerical model is presented and the simplifying assumptions are discussed in detail. The molecular-kinetic theory introduced by Blake is used to describe the effect of dynamic contact angle on fluid ...
