Some pore systems gain quality as a result of diagenesis. The general trend of pore system quality with time and burial, however, is toward destruction. Certain processes can temporarily interrupt this trend. These are “preserved” pore systems. Some of the processes that preserve pore systems are as follows:<ref name=ch09r18>Feazel, C., T., Schatzinger, R., A., 1985, Prevention of carbonate cementation in petroleum reservoirs, in Schneidermann, N., Harris, P., M., eds., Carbonate Cements: SEPM Special Publication 36, p. 97–106.</ref>
