Fluorous additives for use in a fluorous-based treatment fluid

A method of treating a portion of a well comprising:

• forming a treatment fluid, wherein the treatment fluid comprises:
• (A) a liquid fluorinated compound;
• and
• (B) at least one additive,
• wherein the additive:
• (i) comprises carbon and at least one fluorine functional group;
• (ii) is soluble or dispersible in the liquid fluorinated compound;
• and
• (iii) is selected from the group consisting of a fluid loss additive, lost-circulation material, corrosion inhibitor, lubricant, viscosifier, sweeping agent, oxygen scavenger, emulsifier and combinations thereof, and wherein the at least one additive is selected from the group consisting of perfluoropolystyrene, perfluoropolytert-butylstyrene, fluorinated polysaccharides, perfluorinated fatty acids, perfluoropolystyrenebutadienes, perfluoropolyethylene ethene/butene copolymer, fluorinated fibers, fluorinated elastomers, tetrafluoropropanol, octafluoropentanol, dodecafluoroheptanol, derivatives of any of the foregoing, and combinations thereof;
• (C) at least one additional additive comprising a high-temperature stabilizer selected from the group consisting of arylamines, benzimidazole, phenyl-beta-naphthylamine, triphenylimidazole, triphenylphosphine sulfide, tetraphenylhydrazine, tetraphenyltetrazocine, perfluorotriphenylphosphine, phenyl diselenide, perfluoroalkylether phosphines, diphosphatetraazacyclooctatetraenes, monodiphospha-s-triazines, diphospha-s-triazenes, derivatives of any of the foregoing, and any combination thereof;
• and
• introducing the treatment fluid into the well, wherein the treatment fluid does not comprise polytetrafluoroethylene.
