1. OilcastNot much change from previous oil forecasts for Pensacola Beach. We remain well within the "uncertainty" area of NOAA's potential forecast of washed-up tarballs and mousse, but so far this week only about one percent of Pensacola Beach
has been reported covered with "sporadic tarballs." Light southwest winds and off-and-on overcast conditions continue.
2. Pressure Test Postponed.First the
"well integrity" pressure tests were to start "immediately" after the new "18-foot-tall, 150,000-pound" stack cap was seated. Then, it was Monday. Then Tuesday morning. Then Tuesday by noon. Then Tuesday mid-afternoon. Then evening.
Now it may not be until Thursday -- if ever -- before pressure tests on BP's new cap stack begin. The
New York Times and
Bloomberg News were among the first to report late last night that start of the pressure testing --
was postponed after BP met with National Incident Commander Thad Allen, Energy Secretary Steven Chu and a government team of scientists and industry experts, who decided more analysis needed to be done before they proceeded, Allen said in a statement last night.
"We continue to prepare and review protocols for the well integrity test, including the seismic mapping run that was made around the well site this morning," Allen said. "As a result of these discussions, we decided that the process may benefit from additional analysis."
As the Times explains:
On its Web site, BP said in a statement that the test had been postponed after a meeting with Energy Secretary Stephen Chu “and his team of scientific and industry experts.”
According to
a statement issued a little after 8:30 CDT last night, Admiral Thad Allen and Secretary Chu's group, seismic mapping of the seafloor yesterday morning
convinced them "that the process may benefit from additional analysis that will be performed tonight and tomorrow."
BP's well bore is more than 12,000 feet, or 2+ miles into the Earth below the seafloor. There always has been concern that merely by "pressure testing" the new cap stack the oil company conceivably could cause additional, irreparable damage to the stack or the well itself, thus complicating or even negating August's relief well efforts. Hence, BP has issued multiple assurances that it would proceed slowly to close three open vent in the stack while trying to achieve higher pressures inside the stack; and it would re-open the vents if pressure dropped because that would signal problems below the seafloor.
Now, it seems, seismic imaging has caused concerns that the well bore, or the rocky formations around it beneath the seafloor, may have been compromised by the original April 20 explosion. As Rolling Stone Magazine's
Osha Gray Davidson wrote late last night:
Allen’s reference to an already performed “seismic mapping run” as a reason for delaying the test, suggests the possibility of a second even more serious problem. Geologists may have detected cracks or fissures in the rock surrounding the well, weaknesses probably caused by the initial explosion. If that’s true, the area may not be stable enough to proceed with the well test. The pressure generated by shutting off the flow of oil could lead to a catastrophic failure of the well — allowing crude to spew into the water at a rate even greater than it already is.
Sound familiar?
3. NPR's Leaking Coverage.For some reason National Public Radio's coverage of the oil spill has been leaking a lot of oil lately. It's all surface and no depth. Faced with what may be the biggest man-made environmental disaster in history, so far as we can tell NPR has no correspondents on the leak scene or along the Gulf Coast.
This morning, NPR science reporter Richard Harris, still sitting at his desk in Washington D.C., continues his superficial "analysis" by confessing on air that he gets his information by "watching the robot under water" and that he really doesn't know what's going on or why. But,
'Rah-rah BP! It's all so exciting!Confronted with a glass of oil and asked if it's half-full or half-empty, Harris would say it looks full to him -- and then he'd drink it. Give a listen if you have time to waste:

I don't know if it is something related to a joke or education but at least they want to highlight a problem.
