Unformatted text preview: at the rig crew detected or attempted to address this anomaly. Instead, the crew proceeded to attempt to conduct the first negative test. Well data and testimony establish that the rig crew closed the annular around 5:00 p.m. and attempted to conduct a negative test by first bleeding off the drill pipe pressure from 2,324 psi to 1,427 psi. The rig crew then opened the kill line valve, presumably to try to balance the kill line and drill pipe pressure. As the kill line pressure fell to 0 psi, the drill pipe pressure remained at 458 psi, thus indicating that the crew may not have fully displaced the spacer from below the BOP stack. At approximately 5:05 p.m., the crew shut in the drill pipe, and concurrently the drill pipe pressure increased. The increase in drill pipe pressure is evidence of an unsuccessful negative test and showed that the well was possibly flowing. In addition, the fact that the choke pressure remained less than 0 psi shows that the negative test was likely either unsuccessful or, at the very least, inco...
