Abstract
Disclosed is a coating for inhibiting the formation of scales on one or more surfaces of a component used in the production of subsurface fluids. The coating comprises a diamond-like carbon structure doped with a dopant, such as silicon, titanium, fluorine, oxygen, or chromium. The dopant comprises between about 10% and about 40% of the coating by atom.
Claims18
An article having a scale-inhibiting coating, comprising:
- an article used in the production of subsurface fluids;
- and
- a coating applied to at least one surface of the article, the coating comprising a diamond-like carbon structure doped with a dopant, the coating comprising the dopant at a concentration of between about 10 and about 40 atomic percent.
An apparatus for production of a subsurface fluid, comprising:
- one or more components configured to contact a subsurface fluid;
- and
- a scale-inhibiting coating deposited on one or more surfaces of the one or more components, the coating comprising a diamond-like carbon structure doped with a dopant, the coating comprising the dopant at a concentration of between about 10 and about 40 atomic percent.
