===Carbonate pore systems===
In comparison to clastic pore systems, pore types in carbonate rocks are more varied (see [[Carbonate reservoir models]]). Three basic pore groups can be recognized:<ref name=pt05r34>Choquette, P.

Seven porosity types (interparticle, intraparticle, intercrystal, moldic, fenestral, fracture, and vugs) are common and volumetrically important.
