→Petrophysical classification of carbonate pore space
The Archie<ref name=pt06r5>Archie, G. E., 1952, Classification of carbonate reservoir rocks and petrophysical considerations: AAPG Bulletin, v. 36, p. 278–298.</ref> classification was the first attempt at relating rock fabrics to petrophysical rock properties. Lucia<ref name=pt06r79>Lucia, F. J., 1983, Petrophysical parameters estimated from visual descriptions of carbonate rocks—a field classification of carbonate pore space: Journal of Petroleum Technology, March, p. 629–637.</ref> improved on the Archie classification by defining the pore size distribution in relationship to the particle size and the spatial relationship of the pore space to the particles.

''Interparticle porosity''<ref name=pt06r79 /> is defined as that pore space located between grains (intergranular porosity) or between crystals (intercrystalline porosity), but which is not significantly larger than the grains or crystals. ''Vuggy porosity'' is defined as pore space larger than or within rock particles. Isolated vugs are called ''separate vugs'', while vugs that form a connected pore system on a reservoir scale are called ''touching vugs''. (For more information on porosity, see the chapter on “[[Porosity]]” in Part 5.)
