Abstract

A treatment fluid comprises: a liquid fluorinated compound; and at least one additive, wherein the additive: (A) comprises carbon and at least one fluorine functional group; and (B) is soluble or dispersible in the liquid fluorinated compound. A method of treating a portion of a well comprises: forming the treatment fluid; and introducing the treatment fluid into the well.

First claim

What is claimed is:

1. A treatment fluid comprising:
a liquid fluorinated compound;
and at least one additive, wherein the additive:
(A) comprises carbon and at least one fluorine functional group;
(B) is soluble or dispersible in the liquid fluorinated compound; and
(C) is selected from the group consisting of perfluoropolystyrene, perfluoropolytert-butylstyrene, perfluorinated polystyrene, perfluorinated polyamides, fluorinated polyamides, perfluoropolyacrylamides, perfluorinated tall oil fatty amides, fluorinated polysaccharides, perfluoropolystyrenebutadienes, and combinations thereof,
wherein the liquid fluorinated compound includes at least one other halogenated functional group other than a fluorine functional group.

2. The fluid according to claim 1 , wherein the liquid fluorinated compound comprises a perfluorinated liquid compound.

3. The fluid according to claim 1 , wherein the treatment fluid is a solution.

4. The fluid according to claim 3 , wherein the liquid fluorinated compound is the solvent and the additive is the solute.

5. The fluid according to claim 1 , wherein the treatment fluid is a colloid.

6. The fluid according to claim 5 , wherein the treatment fluid is a slurry, an emulsion, or a foam.

7. The fluid according to claim 6 , wherein the liquid fluorinated compound is the external phase of the treatment fluid, and wherein the additive is the internal phase of the colloid;
the solute of any of the phases of the colloid; or is an undissolved solid in any of the phases of the colloid.

8. The fluid according to claim 1 , wherein the additive comprises two or more fluorine functional groups.

9. The fluid according to claim 1 , wherein the treatment fluid comprises two or more additives.

10. The fluid according to claim 1 , wherein the additive is a fluid loss additive, lost-circulation material, corrosion inhibitor, lubricant, viscosifier or suspending agent, sweeping agent, emulsifier, or oxygen scavenger.

11. The fluid according to claim 1 , wherein the treatment fluid further comprises at least one additional additive.

12. The fluid according to claim 11 , wherein the at least one additional additive is a high-temperature stabilizer, a pH buffer, a weighting agent, an acid, proppant, an alkalinity source, a shale stabilizer, a biocide, a scavenger, a surfactant, a thinner, a flocculent, a deflocculent, a bridging agent, a breaker, and a dispersant.

13. The fluid according to claim 12 , wherein the high-temperature stabilizer is selected from the group consisting of alkylene diamines, arylamines, benzimidazole, phenyl-.beta.-naphthylamine, triphenylimidazole, triphenylphosphine sulfide, tetraphenylhydrazine, tetraphenyltetrazocine, perfluorotriphenylphosphine, phenothiazine, phenyl diselenide, perfluoroalkylether phosphines, diphosphatetraazacyclooctatetraenes, monodiphospha-s-triazines, diphospha-s-triazenes, derivatives of any of the foregoing, and any combination thereof.

14. A treatment fluid comprising:
a liquid fluorinated compound, wherein the liquid fluorinated compound comprises carbon and at least one fluorine functional group; and
at least one additive, wherein the additive:
(A) comprises carbon and at least one fluorine functional group;
(B) is soluble or dispersible in the liquid fluorinated compound;
(C) is a fluoropolymer; and
(D) wherein a monomer residue used to form the fluoropolymer is selected from the group consisting of vinyl fluoride, vinylidene fluoride, perfluoropropylvinylether (PPVE), perfluoromethylvinylether (PMVE), chlorotrifluoroethylene (CTFE), and any combination thereof,

wherein the liquid fluorinated compound includes at least one other halogenated functional group other than a fluorine functional group.

15. A treatment fluid of claim 14 , wherein the treatment fluid is a drilling fluid, spacer fluid, completion fluid, work-over fluid, production enhancement fluid, or a packer fluid.

16. The treatment fluid of claim 14 , wherein the monomer residue used to form the fluoropolymer is vinyl fluoride.
