Abstract: Nano-sized mixed metal oxide carriers capable of delivering a well treatment additive for a sustained or extended period of time in the environment of use, methods of making the nanoparticles, and uses thereof are described herein. The nanoparticles can have a formula of:

A/[Mx1My2Mz3]OnHm

where x is 0.03 to 3, y is 0.01 to 0.4, z is 0.01 to 0.4 and n and m are determined by the oxidation states of the other elements, and M1 can be aluminum (Al), gallium (Ga), indium (In), or thallium (Tl). M2 and M3 are not the same and can be a Column 2 metal, Column 14 metal, or a transition metal. A is can be a treatment additive.
