Ideally, ''all'' core should be preserved. The method of preservation and packaging of cores varies depending upon the type of core (consolidated versus unconsolidated), the core analysis measurements required, and the length of time the core is stored before testing.

Core preservation methods are typically either "dry" or "wet." Dry methods enclose the core in a material that prevents evaporation of formation fluids. Wet methods of preservation involve submerging the core in a brine or other fluid that preserves core [[wettability]].<ref name=Basan_etal_1988>Basan, P., J. R. Hook, and K.

A variety of dry and wet preservation methods used by the industry are summarized in [[:File:Table_rose_time-value-of-money_1.jpg|Table 1]]. Note that none of these methods provide an ideal solution to core preservation.
