Admiral Allen’s statement:

I have received extensive briefings over the last 24 hours regarding the final effort to intercept the Macondo well.  Through a combination of sensors embedded in the drilling equipment and sophisticated instrumentation that is capable of sensing distance to the well casing, BP engineers and the federal science team have concluded that the Development Driller III relief well has intersected the Macondo well.  This determination was made based on a loss of drilling fluids that indicated communication had been established beyond the relief well, the pressure exerted against the drill bit as it came in contact with the well casing and, finally, an increase in pressure in the choke line of the Macondo well blow out preventer.  While each of these indicators taken separately would not necessarily be conclusive, the aggregate data available supports the conclusion that the two wells are joined.  It is also important to note that none of the measurements supported a scenario where the annulus of the well is in communication with the reservoir.  Accordingly, we intend to proceed with preparation to cement the annulus and complete the bottom kill of the well.  Further information will be provided as cementing procedures are completed.

Observations:

1. The relief well engineering team and crew performed exceptionally despite the many distractions and interruptions. Outstanding work.
2. The new ranging and sensing equipment, combined with real-time measurement-while-drilling technology, made this complex operation seem routine.
3. The above report seems to confirm that the annulus had been sealed with cement above the producing reservoir.  This was accomplished either when the production casing was cemented prior to the blowout or during the top-kill operation, presumably the former.
4. There was no report of oil in the mud returns or other evidence of of oil in the annulus surrounding the production casing.  If no oil was encountered in the annulus, this would seem to confirm BP’s conclusion that the well flowed inside the production casing.
5. Flow was stopped by the capping stack on July 15, and the Macondo well was killed when mud and cement were injected during the top-kill operation.  Since the well was already dead, the cementing of the annulus that will follow is actually part of the plugging and abandonment operation.  While the annulus could have been secured through more conventional plugging procedures, this does not detract from the relief well team’s extraordinary achievement.
