This paper is an overview of coated and non-coated well casings in corrosive formations. Failure trend studies of externally un-coated well casings indicate a prevalence of external casing failures due to corrosive formations. Some casing failures have been documented in as little as twenty-four months. Well casings coated with advanced technology epoxies have improved the service life of these wells significantly. This paper describes the key learnings from these applications.
