Key BP Oil Well Test Delayed - US Official, July 13, 2010:
The start of BP PLC's (BP) crucial integrity test of the leaking Gulf of Mexico oil well has been delayed until at least Wednesday, the U.S. official leading the disaster response said. Adm. Thad Allen, the former U.S. Coast Guard chief, said he had taken the decision to delay the test after meetings with Energy Secretary Steven Chu, a Nobel Prize-winning physicist, and other top experts.
"As a result of these discussions, we decided that the process may benefit from additional analysis that will be performed tonight and tomorrow," Allen said in as statement. ...
Low pressure would indicate oil was seeping out of the external casing of the well, meaning the valves would have to be reopened to reduce the risk of causing a new gusher on the seabed. Containment operations would then have to resume.
