Cathodic protection of well casings offshore
Journal Article

· J. Pet. Technol.; (United States)
Wells completed from offshore platforms have unique cathodic protection (CP) problems because they are shorted electrically to the platforms. Thus, there is no convenient way to determine how much galvanic or impressed current flows in each well casing system. Also, most platforms are protected with sacrificial anodes, and the depth to which they protect well casings is unknown. Furthermore, there are no established protection criteria applicable to offshore well casings attached to platforms. This study was performed to investigate the effects of galvanic current and impressed current CP on an offshore platform and six wells, and some CP guidelines were established.
