The Effect of Viscosity on Relative Permeabilities Derived from Spontaneous Imbibition Tests
Spontaneous imbibition experiments are usually carried out on All Faces Open or One End Open cores and this severely limits the information that can be obtained because imbibition can be approximately describe...

Spontaneous Counter-Current Imbibition into Core Samples with All Faces Open
Counter-current imbibition occurs when brine spontaneously displaces oil from a very strongly water-wet rock. Experiments are usually carried out on cylindrical core plugs which have all of their faces open, m...

An Approximate Analytical Solution for Counter-Current Spontaneous Imbibition
An approximate analytical solution is provided for one-dimensional, counter- current, spontaneous imbibition of a wetting phase (water) into a semi-infinite porous medium. The solution is based on the assumpti...
