| Summary: | CO2 corrosion of carbon steel in the presence of deposits is a major concern in the oil and gas industry as the deposits impair effective corrosion inhibition and promote localized corrosion. This study shows that the extent of corrosion is affected by the nature of the mineral deposit. Chukanovite and siderite were identified as corrosion products formed at sand-deposited carbon steels. Sulphur-containing organic compounds showed low affinity for sand and effectively inhibited general corrosion at sand-deposited steels. |
