Narrative
Approximately 18 bbls of crude oil were released from the bottom portion of plains 10-inch baggs to wamsutter pipeline during a recoat project. The failure was a result of an internal corrosion pit. The failed pipe has been sent to a lab to undergo metallurgical analysis. A supplemental report will be submitted once the results of this analysis are received. The pipe was replaced and has returned to service. Supplemental narrative: the metallurgical analysis concluded that the corrosion occurred in the presence of produced water containing a mixture of oxygen and carbon dioxide. The pit morphology suggests that microbially induced corrosion (mic) was a significant contributing factor. Plains has now increased the frequency in which this line is pigged, from a monthly basis to a weekly basis and will continue to do so until there are no signs of sludge or water crystals.
