===Calcium carbonate cementation and compaction===

Calcium carbonate [[Postaccumulation cementation|cementation]] and [[Reservoir quality#Compaction|compaction]] are diagenetic processes that are initiated soon after deposition and by which [[Porosity#Carbonate pore systems|intergranular pore space]] is progressively reduced producing systematic changes in petrophysical properties (see [[Evaluating diagenetically complex reservoirs]] and [[Reservoir quality]]). Compaction is a physical/chemical process, while cementation requires fluid flow. [[Microporosity]] within grains or between lime mud particles may be retained even though intergranular pore space is lost.
