The flow characteristics of [[carbonate]] reservoirs are controlled by a combination of [[Carbonate reservoir models: facies, diagenesis, and flow characterization#Carbonate reservoir models|depositional]] and [[Carbonate reservoir models: facies, diagenesis, and flow characterization#Diagenesis|diagenetic]] processes. Depositional processes control the initial [[Pore and pore throat sizes|pore size]] distribution and the geometry of the individual depositional facies. The diagenetic overprint modifies the pore size distribution and controls the productivity of depositional facies. In some cases, [[reservoir quality]] and flow characteristics are totally controlled by diagenesis, as in karsted reservoirs.

Carbonate reservoir descriptions are based on observations of depositional and diagenetic fabrics and pore space from [[Overview of routine core analysis|core]] and [[Analysis of cuttings|cuttings]] samples. The descriptions are correlated with [[Basic open hole tools|wireline log]] responses and incorporated into geological facies and/or diagenetic models in order to map [[porosity]], [[Interpreting Sw distribution in a reservoir|saturation]], and [[permeability]].
