The disposal of salt water produced with oil from the East Texas field has been successful in minimizing pollution of land areas and freshwater sources, and has also been effective in maintaining bottomhole pressure. To date, 4.5 billion bbl of salt water has been returned to the producing reservoirs at a cost to the operators of approximately 2.5tf/bbl.

At Hastings field, in Brazoria and Galveston Counties, Texas, Amoco is successfully disposing of 50,000-60,000 bbl/day of salt water by injection into saltwater-bearing formations below freshwater sandstones and above the oil-producing zones. The project is a “closed system,” whereby the salt water produced is allowed no contact with air; thus, corrosion attack on disposal facilities is reduced. To date, Amoco has injected approximately 500 million bbl of salt water.
