Narrative
Third party notified enterprise local operations of a leak on the c150 regulated gathering line. Approximately 20 bbls of crude oil was released on to the ground with 2 bbls entering a dry creek bed with no water impact discovered. A temporary clamp was placed on the line for overnight. The line was replaced the next day and put back into service. The replaced line was sent for metallurgical analysis. Remediation and repairs were completed. Metallurgical report confirmed that external corrosion and microbiological- assisted corrosion contributed to wall loss and eventually a leak in the pipe. The line is being purged and capped and placed in an idled operating status. Future intent is to abandon the line.
