What caused the Deepwater Horizon disaster?

by

The blowout and oil spill on the Deepwater Horizon in the Gulf of Mexico was caused by a flawed well plan that did not include enough cement between the 7-inch production casing and the 9 7/8-inch protection casing. The presumed blowout preventer (BOP) failure is an important but secondary issue. Although the resulting oil spill has potentially grave environmental implications, recent efforts to limit the flow with an insertion tube have apparently been effective. Continuous efforts to slow or stop the flow include drilling two nearby relief wells that may intersect the MC 252 wellbore within 60-90 days.

Oil prices fell below $70/barrel this week before recovering slightly. The drop reflected market nervousness about the gravity of the Euro crisis and its potential impact on the global economy, coupled with continued high US crude oil stocks. In the meantime all eyes continue to be focused on the Gulf of Mexico where challenges to BP’s estimate of the size of the oil spill is further damaging the credibility of the company…

The relentless pursuit of extreme energy

Yes, the oil spewing up from the floor of the Gulf of Mexico in staggering quantities could prove one of the great ecological disasters of human history.  Think of it, though, as just the prelude to the Age of Tough Oil, a time of ever increasing reliance on problematic, hard-to-reach energy sources.  Make no mistake: we’re entering the danger zone.  And brace yourself, the fate of the planet could be at stake.

No mass media is as pervasive or intrusive as the American one. Now that we’ve stopped making stuff, more or less, we’re still super prolific at selling our own image. This hypnosis works even on Americans, who should know better. But we don’t live here so much as inside media. The average American watches four hours of television a day, listens to constant music, and there’s also the internet with its Facebook, texting, twitter and email, etc, to distract him.

Stupak stunner: Oil well’s blowout preventer had leaks, dead battery, design flaws

by

A senior House Democrat said that the blowout preventer that failed to stop an oil leak in the Gulf of Mexico had a dead battery in its control pod, leaks in its hydraulic system, a “useless” test version of one of the devices that was supposed to close the flow of oil and a cutting tool that wasn’t strong enough to shear through joints that made up 10 percent of the drill pipe.

How the BP oil spill is affecting New Orleans schools

When BP’s Deep Water Horizon well exploded in the Gulf of Mexico on April 20, it was difficult to imagine the scope of its impact on the delicate coastlines of Louisiana and adjacent states. Today, the former platform site continues to spill about 5,000 barrels a day – or 210,000 gallons – into the Gulf, with no containment strategy yet in sight.

From the Deepwater Horizon

The Gulf of Mexico “spill” is really a man-made underwater volcano of oil. This accident taps a primeval fear in the human mind. Something dark and uncontrollable rushes out of the Earth, poisoning the global oceans. Could that really happen?
