WaPo writer "can't imagine" Macondo well has come back ... Top expert: "Looks suspicious" -- There may be a pathway for oil to move up via annulus


Oil spill: Revisiting the Well From Hell, Washington Post by Joel Achenbach, August 26, 2011:

[...] We recall that, last summer, the doomsday scenario was that in capping the well they would trigger an underground blowout and sent hydrocarbons into the formation and up into the gulf. That didn’t happen. And they stared at this thing a long time. I can’t imagine that a year after it was throttled with a mile of cement the well has come back to life in some way. [...]

Bob Bea, a prominent University of California petroleum engineer:

  • "Perhaps connections that developed between the well annulus (outside the casing), the reservoir sands about 17,000 feet below the seafloor, and the natural seep fault features (could provide a pathway for oil to move from deep underground to the seafloor)."
  • "Looks suspicious. The point of surfacing about 1 mile from the well is about the point that the oil should show up, given the seafloor at 5,000 feet ... natural circulation currents would cause the drift."

Deepwater trouble on the horizon: oil discovered floating near source of Gulf of Mexico spill (Photo gallery, video), Press-Register by Ben Raines, August 24, 2011:

[...] The Press-Register reporters located the area where the oil was rising to the surface by going to a point directly over the Macondo well and then moving in the direction of the prevailing surface current. The first blobs of oil seen on the surface were detected about a half-mile from the well. The frequency of the sightings increased gradually over the next half-mile.

In the Olympic swimming pool-sized area where the oil was rising most frequently, new sheens were erupting every few seconds on all sides of the 36-foot boat. [...]
