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 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.

2. The method according to claim 1 , wherein the well is an oil, gas, or water production well, or an injection well.

3. The method according to claim 1 , wherein the treatment fluid is a drilling fluid, spacer fluid, completion fluid, work-over fluid, production enhancement fluid, or a packer fluid.

4. The method according to claim 1 , wherein the liquid fluorinated compound comprises carbon and at least one fluorine functional group.

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

6. The method according to claim 5 , wherein the liquid fluorinated compound is a solvent and the at least one additive is a solute.

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

8. The method according to claim 7 , wherein the treatment fluid is a slurry, an emulsion, or a foam.

9. The method according to claim 8 , wherein the liquid fluorinated compound is an external phase of the colloid, and wherein the at least one additive is an internal phase of the colloid or a solute of any phases of the colloid.

10. The method according to claim 1 , wherein the at least one additive comprises two or more fluorine functional groups.

11. The method according to claim 1 , further comprising the step of removing at least a portion of the treatment fluid after the step of introducing.

12. The method according to claim 1 , wherein the treatment fluid treats a subterranean formation.
