Narrative
On saturday, november 23, 2013, at 08:45, a chaparral energy employee received a call from a third party person notifying him of a possible release in the beaver, ok area. The chaparral energy employee notified the local pipeline employee who immediately notified his boss, the local pipeline tech supervisor. The pipeline tech supervisor put chaparral energy's emergency response plan into action at that point. The chaparral energy pipeline employee arrived at the release site at 10:07 and confirmed that it was in fact chaparral energy's pipeline. The downstream valve was closed at 10:28 and the upstream valve was closed at 10:45. At 10:45, blowdown of the section began at the upstream valve site. Blowdown was completed at 12:45. At 13:15, chaparral energy's contractor arrived onsite and began evacuating the release site. On sunday, november 24, 2013, at 13:00, approximately 65 feet of existing pipe was removed and replaced with pre-tested pipe. At 17:45, chaparral energy began refilling the section. At 18:05, the line was placed back into service. The exact cause of this accident is still being investigated. The removed section of pipe is at a testing lab and chaparral energy is waiting for the results of the investigation. Update: chaparral energy received the final report from the testing lab. The determined cause of the accident as stated by the testing lab is "failure of the line pipe was a result of a manufacturing defect". The time of the accident is still being determined. The estimated pressure may also change due to the fact that the time the accident occurred is still unknown. Update: chaparral energy has concluded its accident investigation and has determined that the accident occurred at 06:00 on 11/23/13. The pressure on the pipeline at that time was 1200 psi. This report is being updated to reflect the cause and time of the accident. For question 14.A - the time had to be changed from 09:40 to 10:07 because there was an error message from the system that said the time had to be equal to or greater than the time and date on question 4.
