BP drilling relief well, building containment domes
BP announced Tuesday that it began drilling a relief well to intercept and isolate the oil well that is spilling oil in the Gulf of Mexico. Work on the relief well has actually been under way since Sunday. The new well, in 5,000 feet of water, aims to intercept the existing well around 13,000 feet below the seabed and permanently seal it.
The new drill site is about half a mile on the seabed from the leaking well in Mississippi Canyon block 252, and drilling is estimated to take three months.
In the meantime, construction has been completed on a containment dome, a massive 4-story structure the company plans to lower into place over one of the three leaks to capture the escaping oil and pump it to the surface. Two more domes should be completed today, and crews hope to install all three domes by the end of the week, CNN reports.
Once lowered over the leak site and connected by pipe, the canopy is designed to channel the flow of oil from the subsea to the surface where it could be processed and stored safely on board a specialist vessel. Watch a CNN video about how BP hopes these containment domes will work.
BP has also carried out a second approved trial injection of dispersants directly into the oil flow at a point close to the main leak on the seabed. The technique is intended to efficiently mix the oil and dispersant, breaking up and dispersing accumulations of oil and allowing it to degrade naturally and reduce surface impact. This innovative technique was suggested by companies across the oil industry that BP approached last week for more ideas and expertise on tackling the spill.
BP’s most recent efforts come as the National Oceanic and Atmospheric Administration is stating that the oil slick appears to be drifting toward the Alabama and Florida coasts and the Chandeleur Islands off Louisiana’s southern tip.
Listen here to an exclusive April 30 interview with a rig survivor, “James,” on The Mark Levin Show. While the show chose not to use James’ real name, it did confirm that James was on the rig when it blew up. James discusses possible causes of the explosion and efforts to contain the leaks, including numerous details about the incident not yet made public.

DEC 12 Until recently, it seemed like NOLA Mayor Mitch Landrieu was going to skate to re-election. But John Maginnis writes in this post that he may face some unexpected opposition, from Michael Bagneris, who currently serves as a civil court judge for the city. The judge isn't saying he's thinking about it, because then he would have to step down, but let's just say Maginnis won't be surprised if Bagneris turns up to qualify for the job.
DEC 12 Louisiana Congressman Steve Scalise, chair of the Republican Study Committee, has dumped the RSC's director, this post on Politico tells us. The director, Paul Teller, is accused of leaking conversations with lawmakers, the post says, and "actively working against" strategies that committee members had come up with. Hmmmm....
DEC 12 Jeremy Alford gives us the latest on David Duke in this LaPolitics post. Duke is back in the headlines because he was expelled from Italy recently, accused of trying to start a Neo-Nazi group there. Alford's pulled some interesting bits from the recent media coverage and some older pieces as well about this state embarrassment.
DEC 12 So Louisiana has one of the highest rates of HIV infection in the nation, we've known that for a while. But this Picayune story tells us about a new report by Human Rights Watch that says our laws and law enforcement practices are to blame. Those practices impact two routes to infection: unprotected sex and shared needles, the story says.
DEC 12 Jim Brown blogs about a book, "Dumbest Generation," and bemoans our inability to attain a more positive adjective. Jim wants to know: with our constant, unfettered access to information, why aren't we greater? He may be answering the question himself, urging more focus on community service and less on self-enrichment.
DEC 12 Here's an interesting post from DIG Baton Rouge about the proposed City of St. George in Baton Rouge. This piece focuses on the school district the organizers want to create. They're confident they won't need to raise taxes (because, of course, they'll be grabbing huge chunks of tax dollars -- or at least they think so) to build new schools, the story says.
DEC 12 After weeks of "political gimmicks" aimed at trying to force a vote on something most people really don't understand, Sen. David Vitter has decided he will do exactly what Sen. Mary Landrieu already has done for his own Congressional health insurance, the Advocate reports here. Senate leaders offered him a vote, but he didn't want it -- some say because he hadn't milked all the political juice out of this alleged issue yet.
DEC 12 The fact that "amateurs" are running the education system in Louisiana is hurting our children, blogger Mike Deshotels writes in this post. In support of his argument, he goes through the recent vote on Common Core in Baton Rouge, and explains what the data showed. It's not a pretty picture.
