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. Hughes, 1988, Measuring porosity, saturation, and permeability from cores: The Technical Review, v. 36, n. 4, p. 22-36.</ref>. 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.
