hydrocarbon reservoirs in North America were used to quantitatively study diagenetic alterations of pore systems. Results were most favorable for rocks in which no early cementation or secondary replacement occurred and for which the pore system could be characterized sedimentologically.

Geologic modeling of Previous HitpermeabilityNext Hit/porosity crossplots may reveal secondary Previous HitpermeabilityNext Hit that results Previous HitfromNext Hit microstructural damage, fracturing, and/or directional dissolution.

Analyses of Previous HitpermeabilityTop/porosity crossplots may establish the relative timing of the various diagenetic modifications.
