I need some info on salt water disposal for a project. If anyone has anything on it, it would be greatly appreciated. Thanks.

Salt water disposal wells are very similar to water disposal wells, the only difference is that, in salt water disposal wells, the salinity of the water is very high and as such they can not be injected into the level at which potable water is present. There are two different approaches :
1) Returned by fluid injection into the reservoir where it originated for secondary or enhanced oil recovery;
or 2) Injected into underground porous rock formations not productive of oil or gas, and sealed above and below by unbroken, impermeable strata. Saltwater disposal wells use this second method to manage saltwater.
It is common practice to backflow saltwater injection wells from time to time to remove some of the foreign materials that have accumulated on the formation at the bottom of the hole. Acidizing the injection well also helps to clean the formation.
