Title (EN) METHOD OF PREVENTING OR MITIGATING FORMATION OF METAL SULFIDE SCALES DURING OIL AND GAS PRODUCTION
(FR) PROCÉDÉ POUR EMPÊCHER OU ATTÉNUER LA FORMATION DE DÉPÔTS DE SULFURE MÉTALLIQUE LORS DE LA PRODUCTION DE PÉTROLE ET DE GAZ
Abstract:
(EN) A method of preventing or mitigating the formation of metal sulfide scale in a fluid is provided. The fluid can be treated with an additive comprising thiamine. The fluid can be a production fluid from an oil and gas well. The production fluid can include crude oil. The fluid can include an aqueous fluid. The aqueous fluid can further include crude oil. The metal sulfide scale can include iron sulfide scale and/or zinc sulfide scale.
(FR) L'invention concerne un procédé destiné à empêcher ou atténuer la formation de dépôt de sulfure métallique dans un fluide. Le fluide peut être traité avec un additif comprenant de la thiamine. Le fluide peut être un fluide de production provenant d'un puits de pétrole et de gaz. Le fluide de production peut contenir du pétrole brut. Le fluide peut contenir un fluide aqueux. Le fluide aqueux peut en outre contenir du pétrole brut. Le dépôt de sulfure métallique peut contenir un dépôt de sulfure de fer et/ou un dépôt de sulfure de zinc.
