Abstract
Petrophysical units, or rock types, are defined to help petrophysicists assign characteristics to different zones of a reservoir. Rocks are clustered into groups assumed to have similar flow and storage capacity. Facies are identified by geologists, who use depositional and diagenetic criteria tied to porosity-permeability data. Relationships are used to link the petrophysical to the geological models, along with log typing to estimate initial hydrocarbons-in-place. Reservoir engineers also wish to define rock types based on their two-phase flow characteristics (i.e. relative permeability).
