Abstract

Methods and compositions for the use of treatment fluids comprising metalate-based additives to treat subterranean formations are provided. In one embodiment, the methods comprise providing a treatment fluid comprising a non-aqueous base fluid and at least one metalate-based additive comprising: an anion selected from the group consisting of: a tungstate, a molybdate, a vanadate, a manganate, and any combination thereof, and an organic cation; and introducing the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation.

First claim

What is claimed is:

1. A method comprising:
providing a treatment fluid comprising a base fluid and at least one metalate-based additive comprising an anion selected from the group consisting of: a thiotungstate, a thiovanadate, a thiomanganate, and any combination thereof, wherein the at least one metalate-based additive is present in an amount from about 40% to about 95% by weight of the treatment fluid; and
introducing the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation.

2. The method of claim 1 , wherein the treatment fluid further comprises a hydroxylic compound.

3. The method of claim 1 , wherein the metalate-based additive further comprises an inorganic cation.

4. The method of claim 1 , wherein the metalate-based additive further comprises an organic cation.

5. The method of claim 1 , wherein the base fluid is a non-aqueous base fluid.

6. The method of claim 1 , wherein the treatment fluid comprises a polar organic fluid.

7. The method of claim 1 , wherein the metalate-based additive lubricates one or more pieces of equipment in the wellbore.

8. The method of claim 1 , wherein the metalate-based additive inhibits corrosion on one or more surfaces in the subterranean formation or the wellbore.

9. The method of claim 1 , wherein the treatment fluid further comprises one or more weighting agents selected from the group consisting of: a barite, a hematite, calcium, a carbonate, magnesium carbonate, iron carbonate, zinc carbonate, manganese tetraoxide, an ilmenite, a formate salt, NaCl, KCl, CsCl 2 , and any combination thereof.

10. The method of claim 4 , wherein the organic cation is selected from the group consisting of: a quaternary amine, a polymer of a quaternary amine, an ammonium compound, a polymer of an ammonium compound, a phosphonium compound, a polymer of a phosphonium compound, a pyridine, an imidazole, a morpholine and any combination thereof.

11. The method of claim 3 , wherein the inorganic cation is selected from the group consisting of: H + , Li + , Na + , K + , Rb + , Cs + , Mg 2+ , Ca 2+ , Sr 2+ , Ba 2+ , Al 3+ , Ti 3+ , Ti 4+ , Mn 2+ , Mn 3+ , Fe 2+ , Fe 3+ , Cu 2+ , Cu + , Zn 2+ , Zr 2+ , Zr 3+ , Zr 4+ , and any combination thereof.

12. A method comprising:
providing a treatment fluid comprising a base fluid and at least one metalate-based additive comprising an anion selected from the group consisting of: a thiotungstate, a thiomolybdate, a thiovanadate, a thiomanganate, and any combination thereof; and
introducing the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation, wherein upon introduction into the wellbore, the treatment fluid comprises the at least one metalate-based additive in an amount from about 40% to about 95% by weight of the treatment fluid.

13. The method of claim 12 , wherein the treatment fluid further comprises a hydroxylic compound.

14. The method of claim 12 , wherein the metalate-based additive further comprises an organic cation.

15. The method of claim 14 , wherein the organic cation is selected from the group consisting of: a quaternary amine, a polymer of a quaternary amine, an ammonium compound, a polymer of an ammonium compound, a phosphonium compound, a polymer of a phosphonium compound, a pyridine, an imidazole, a morpholine, and any combination thereof.

16. The method of claim 12 , wherein the base fluid is a non-aqueous base fluid.

17. A method comprising:
providing a treatment fluid comprising a base fluid and at least one metalate-based additive comprising a thiotungstate anion; and
introducing the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation.

18. The method of claim 17 , wherein the treatment fluid further comprises a hydroxylic compound.

19. The method of claim 17 , wherein the metalate-based additive further comprises an organic cation.
