BP Has Stopped the Oil From Flowing ... But Is It Only Temporary?

BP has succeeded in capping the well and stopping oil from flowing into the Gulf of Mexico ... at least temporarily.

The official Deepwater Horizon Response Twitter feed noted as of a couple of minutes ago:


This can be confirmed by looking at the underwater video cams.

As of this writing, Skandi ROV 2's cam is showing the cap (no oil), and Skandi ROV 1's cam is showing sonar of the seafloor.

However, numerous industry experts have warned that there is no upside to temporarily capping the well as part of the well integrity test, and that it might actually cause the well to blow out.

Indeed, Don Van Nieuwenhuise - director of geosciences programs at the University of Houston - told CNN today:

We don’t know if there ae significant leaks deep in the well.

There’s a couple of weak points at 9,000 feet, and one at 17,000 feet, that they might be particularly interested in looking and watching in the seismic.

[With seismic testing, you can look beneath the seafloor. Sonar only tests at the seafloor itself].

Admiral Thad Allen previously said that the test will be considered a success if pressure in the well stays at 8,000 psi or higher for 48 hours. So we won't know for a couple of days whether the test has succeeded.

As AP correctly notes:

Now begins a waiting period to see if the cap can hold the oil without blowing a new leak in the well. Engineers will monitor pressure readings incrementally for up to 48 hours before reopening the cap while they decide what to do.

Interestingly, as CNN's Situation Room noted a couple of minutes ago, the cap might soon be re-opened, and closed again only during hurricanes:

Admiral Thad Allen releasing a statement to us just a short while ago…

He cautions “This isn’t over”…

Very interesting here. He talks about the cap as a temporary measure to be used for hurricanes

“It remains likely that we will return to the containment process… until the relief well is completed”

So it looks like the plan is to go back to releasing the oil and letting it pump up to the surface.

So is the well integrity test a meaningless PR stunt, which is delaying completion of the relief wells, and failing to bring us any closer to permanently killing the oil gusher?

Or is it a valuable tool to see if the well can be protected from further damage during a hurricane?

Only time will tell ...

  1. According to one physicist, this could happen:
    "You could over pressurize and cause the pipe to explode, causing many leaks along the pipe," said Michio Kaku

    cross your fingers and hope it does not happen

  2. IMHO If the cap is a stunt - consider what else might be, apart from that, here is a more scientific analysis.
