Abstract
Sulfide stress cracking of a metal component may be inhibited by treating the metal component with a mixture comprising at least one organic aldehyde and at least one surfactant. Such metal components may be those suitable for use in a downhole environment, at a well site, in a storage facility, in a transportation infrastructure, in a refinery facility, and any combination thereof where the metal component may be exposed to hydrogen sulfide.
Claims20
A method comprising:
- inhibiting the sulfide stress cracking of at least one metal component by contacting the metal component with a mixture comprising at least one organic aldehyde and at least one surfactant.
A piece of equipment comprising:
- a metal component treated with a mixture comprising at least one organic aldehyde and at least one surfactant, wherein sulfide stress cracking of the metal component when contacted with hydrogen sulfide is inhibited.
A system comprising:
- a tubular formed at least in part by a metal;
- a mixture contained within the tubular, the mixture comprising at least one organic aldehyde and at least one surfactant, wherein sulfide stress cracking of the metal component when contacted with hydrogen sulfide is inhibited.
