What is a disposal well?

A saltwater disposal well is very similar in structure to a producing oil or gas well. It has production tubing and casing like any other well. Instead of extracting hydrocarbons and water, these wells are used to dispose of the saltwater from other producing wells. The saltwater is injected into porous zones deep within the earth. These zones are able to absorb large amounts of water at reasonable injection pressures.
