Summary
In this chapter we present findings from laboratory and well data analysis showing potentially useful extensions of rock physics diagnostics and data analysis.
Universality of diagenetic trends
Honoring stratigraphic constraints guarantees that a rock physics trend is deposition- and site-specific. Rationalization by effective-medium modeling makes a trend general, determines the domains of its applicability, and thus reduces the risk of using the trend outside the initial data range. As an example of rationalization, consider work by Avseth et al. (2000) in which empirical data trends are supported by effective-medium curves that represent varying sorting and cementation. Such melding of data and theory is a signature of modern rock physics, where the goal is not only to observe and relate but also to explain and generalize. How general are rational rock physics trends? Can they be applied across tiers of deposition and across geographic areas? These are the questions addressed below (see the original publication by Dvorkin et al., 2002).
