Suggestions are presented in this Note about simple but usually ignore
d ways to enhance the reliability and utility of the otherwise interes
ting procedures recently studied (e.g. by Zarcone and Lenormand and in
dependently by Dullien and Dong) for obtaining needed information abou
t the relative importance of the role played by viscous coupling pheno
mena during multiphase flow processes that occur in and through the in
terstices of natural porous media systems. This is done now because of
the persistence of so many perplexing questions and contradicting opi
nions about what has been a controversial subject ever since the appea
rance of Yuster's watershed paper in 1951. Here, the belief herd by at
least a few of the currently publishing authorities is embraced, name
ly that viscous coupling issues will never be fully settled until the
indications of the underlying theoretical interpretations can be fully
confirmed by laboratory observations, hence a disclosure of even mode
st ways to achieve data acquisition enhancements is the motivation for
what is written in what follows.
