Compositions, systems, and methods for removing iron sulfide scale from oilfield components using methyl acrylate
The present disclosure relates to compositions, systems and methods for removing iron sulfide scale from a solid object, such as an oilfield component. The compositions include a carbon-carbon (C—C) double bond with an electron withdrawing group bonded to at least one of the double-bonded carbons.
1. A method of removing iron sulfide scale from an oilfield component with iron sulfide scale, the method comprising applying to the oilfield component a removal material comprising a methyl-acrylate containing composition of the general structural formula:
in an amount and for a time sufficient to remove iron sulfide scale from the oilfield component.
2. The method of claim 1 , wherein the removal material further comprises a polar solvent.
3. The method of claim 1 , wherein the removal material further comprises an additional composition able to remove iron sulfide scale from the oilfield component.
4. The method of claim 1 , wherein at least 80% of the iron sulfide scale is removed from the oilfield component.
5. The method of claim 1 , wherein applying occurs in a sealed container.
6. The method of claim 1 , further comprising recovering the removal material.
7. The method of claim 1 , wherein the oilfield component comprises a perforation, a casing, a production tubular, a valve, a pump, or downhole completion equipment with iron sulfide scale.
8. A system for removing iron sulfide scale from an oilfield component with iron sulfide scale, the system comprising:
a removal material comprising a methyl-acrylate containing composition of the general structural formula:
and
a system for applying the removal material to the oilfield component in an amount and for a time sufficient to remove iron sulfide scale from the oilfield component.
9. The system of claim 8 , wherein the removal material further comprises a polar solvent.
10. The system of claim 8 , wherein the removal material further comprises an additional composition able to remove iron sulfide scale from the oilfield component.
11. The system of claim 8 , wherein at least 80% of the iron sulfide scale is removed from the oilfield component.
12. The system of claim 8 , wherein the system for applying the removal material comprises a sealed container.
13. The system of claim 8 , wherein the system for applying the removal material further comprises a subsystem for recovering the removal material.
14. The system of claim 8 , wherein the oilfield component comprises a perforation, a casing, a production tubular, a valve, a pump, or downhole completion equipment with iron sulfide scale.
15. The system of claim 8 , wherein the oilfield component comprises a tubular and the system for applying the removal material to the oilfield component comprises a container to house the removal material and a connector to supply the removal material to the tubular.
16. The system of claim 15 , wherein the container is a pressurized container.
17. The system of claim 8 , wherein the oilfield component is placeable in a container and the system for applying the removal material to the oilfield component comprises a sealed container in which the oilfield component is placed, a container housing the removal material, and a connector to supply the removal material to the sealed container.
18. The system of claim 17 , wherein the container housing the removal material is a pressurized container.
