Abstract

An organic acid composition for use in oil industry activities, said composition comprising an arylsulfonic acid in water as well as the use of said composition to perform various operations in the oil industry. There is also disclosed a solid acid composition comprising a corrosion inhibitor ready for dissolution and use.

Claims (22)

1. A composition for use in oil industry activities, comprising an arylsulfonic acid in water and a corrosion inhibitor composition comprising: a terpene; a propargyl alcohol or a derivative thereof; at least one amphoteric surfactant; and a solvent.

2. The composition of claim 1 , wherein the arylsulfonic acid is toluenesulfonic acid.

3. The composition of claim 1 , further comprising a metal iodide or iodate.

4. The composition according to claim 1 , further comprising a metal iodide present in a concentration ranging from 100 to 5000 ppm.

5. The composition according to claim 1 , further comprising a metal iodide present in a concentration of 1000 ppm.

6. The composition according to claim 1 , wherein the arylsulfonic acid is present in a concentration ranging from 1 to 99 wt %.

7. The composition according to claim 1 , wherein the arylsulfonic acid is present in a concentration ranging from 1 to 50 wt %.

8. The composition according to claim 1 , wherein the arylsulfonic acid is present in a concentration ranging from 10 to 40 wt %.

9. A method to prepare a solid form organic acid-inhibitor composition for use in oil industry activities, comprising:

providing an arylsulfonic acid in solid form;

providing a liquid corrosion inhibitor composition;

applying the liquid corrosion inhibitor composition on the arylsulfonic acid to form a mixture; and

drying the mixture to produce the solid form organic acid-inhibitor composition.

10. The method according to claim 9 , wherein said arylsulfonic acid is toluenesulfonic acid.

11. The method according to claim 9 , wherein the liquid corrosion inhibitor composition comprises:

a terpene;

a propargyl alcohol or a derivative thereof;

at least one amphoteric surfactant; and

a solvent.

12. The method according to claim 9 , wherein the at least one corrosion inhibitor component is selected from the group consisting of: a terpene; a propargyl alcohol or a derivative thereof; at least one amphoteric surfactant; and a combination thereof.

13. A solid form organic acid composition for use in oil industry activities, comprising an arylsulfonic acid and a corrosion inhibitor component.

14. The solid form organic acid composition according to claim 13 , wherein the corrosion inhibitor component is selected from the group consisting of: a terpene; a propargyl alcohol or a derivative thereof; at least one amphoteric surfactant; and a combination thereof.
