2.4.4 How Much Heterogeneity
to Include?
the key criteria for distinguishing which
model elements are required for
the model
build are:
1. The identification of potential model elements -
a large number may initially be selected as
'candidates' for inclusion;
The ultimate answer to this fundamental ques-
tion depends on a combined understanding of
geology and flow physics. To be more specific,
