Unformatted text preview: closed, the crew was no longer capable of monitoring the drill pipe pressure. Around 6:00 p.m., the crew bled the pressure from the drill pipe to the cementing unit. At that time, the drill pipe was shut in at the cementing unit, and the pressure on the drill pipe increased to 1,400 psi after 30 minutes. As the pressure on the drill pipe increased, the kill line pressure also steadily increased but only to 140 psi. This pressure differential between the drill pipe and the kill line was another indicator that the negative test was not successful. Around 6:45 p.m., the crew pumped a small amount of fluid into the kill line to make sure it was full for another negative test. At approximately 7:15 p.m., the crew opened the kill line to monitor for pressure/flow consistent with the APM approved by MMS. After approximately 40 minutes of no flow or pressure observed on the kill line, the crew and the BP well site leaders deemed the negative test successful and began operations to complete the displaceme...
