15 RhoVeTM Method (U.S. patent pending - copyright 2016) Summary Interactive (and fast). Premised on a continuum of virtual, normally pressured synthetic rock property relationships. Pore pressure is calculated by directly applying RhoVe-derived Velocity & Density-Effective Stress trends. Subsalt Applications Two-parameter approach: a-term & alpha (α); includes the effects of compositional changes (clay diagenesis) Rationale for subdivision of major flow units, which can be utilized in layerbased basin modeling simulations.

32 Chemical Compaction From recent advances in EMI (electron microbeam instrumentation) and sample preparation it is now clear that the principal diagenetic processes of sandstones and limestones, compaction and cementation, also operate in mudrocks (Milliken, K., 2017). **Mudrocks at the Scale of Grains and Pores: Current Understanding, Kitty Milliken, 2017, Bureau of Economic Geology, The University of Texas, Austin.
