# Mercury injection, which simulates the premigration wetting characteristics of the reservoir

The mercury injection method is recommended to evaluate the initial static distributions of reservoir fluids prior to production because these distributions are typically controlled by the premigration wetting characteristics. Mercury injection is also favored because it is simpler, cheaper, and less time consuming than porous plate or centrifuge methods. In addition, mercury injection can be conducted on cuttings or sidewall samples. Mercury injection capillary pressure data can also be converted to the reservoir fluid system. Although this involves a number of assumptions on [[wettability]] and the effects of cleaning and extracting the core are largely ignored, the cost and time benefits typically favor mercury injection.
