''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''.
