Please Pass the Salt: Using Oil Fields for the Disposal of Concentrate from Desalination Plants. Mace, Nicot, Chowdhury, Dutton, and Kalaswad.
The TWDB study conducted for the Bureau of Reclamation investigates the feasibility of disposing desalination concentrates through deep well injection into depleted oil and gas fields that are present in many areas of Texas. The study concludes that deep well injection is technically feasible, but will require regulatory changes.
