At least one alkaline is introduced into the aqueous solution to form an injection fluid having a pH value of at least 10. The cation-ligand complexes remain soluble in the injection fluid such that scale formation is prevented when the injection fluid is injected into a subterranean reservoir.

  • Patent number: 8276663
    Abstract: Methods of treating subterranean formations to reduce bacteria load are provided. Some methods include the steps of providing a treatment fluid, particulates, and tri-n-butyl tetradecyl phosphonium chloride (TTPC) wherein the TTPC is in liquid form or in solution; coating the TTPC onto the particulates; combining the particulates coated with TTPC with the treatment fluid to create a suspension; and, placing the suspension into the portion of the subterranean formation. Other methods involve the use of TTPC in the form of a solid salt.
