1. A corrosion inhibitor composition comprising:

a salt having formula (1):

optionally at least one alkylamine; and

a salt having formula (5):

2. The corrosion inhibitor composition of claim 1 , further comprising a salt of formula (2):

3. The corrosion inhibitor composition of claim 2 , further comprising the salt having formula (6):

a salt having formula (3):

and a salt having formula (4):

4. The corrosion inhibitor composition of claim 1 , further comprising at least one dispersant.

5. The corrosion inhibitor composition of claim 4 , wherein the at least one dispersant comprises at least one oxyalkylate polymer.

6. The corrosion inhibitor composition of claim 1 , further comprising at least one solvent.

7. The corrosion inhibitor composition of claim 6 , wherein the at least one solvent comprises at least one selected from: methanol, ethanol, propanol, isopropanol, butanol, isobutanol, aromatic hydrocarbons, monoethyleneglycol, ethyleneglycolmonobutylether, and combinations thereof.

8. The corrosion inhibitor composition of claim 1 , comprising about 10 wt % to about 100 wt % of the salt having formula (1); the alkylamine; and the salt having formula (5).

9. A method of inhibiting corrosion on a surface in an oil or gas application, the method comprising contacting an effective dosage of the corrosion inhibitor composition of claim 1 with the surface.

10. The method of claim 9 , wherein the effective dosage range is between about 10 ppm to about 10,000 ppm.

11. The method of claim 9 , further comprising dosing the corrosion inhibitor composition into an annulus of a well; allowing the dosed corrosion inhibitor composition to travels into the well; and recovering the corrosion inhibitor composition with a produced fluid thereby avoiding entering a formation.
