Waiting to Find Out if "Top Kill" Worked
Will America's worst oil spill end any time soon? Almost three days after BP began pumping thick mud into its blown-out well, there's still no solid answer.
So far, officials say the "top kill" procedure temporarily stopped the gusher, but it could be Sunday before they know if they can permanently plug the well, reports CBS News correspondent Don Teague.
Teague flew over the Louisiana coast Friday with BP's senior oil spill adviser, who said if the company could just stop the leak, the cleanup in the Gulf could be finished by Labor Day.
"We're talking weeks, not months," he said.

As BP tries to contain and disperse the oil, public frustration is growing.
In New York City, 200 protesters demanded the company take full responsibility for the spill.
Experts said they could see incremental progress at best from BP's "spillcam" of mud, gas and oil billowing from the seafloor. The hypnotic video has become an Internet sensation.
Scientists say the images may offer clues to whether BP is getting the upper hand in its struggle to contain the oil, said Tony Wood, director of the National Spill Control School at Texas A&M University in Corpus Christi. If the stuff coming out of the pipe is jet black, it is mostly oil and BP is losing. If it is whitish, it is mostly gas and BP is also losing.
If it is muddy brown, as it was much of Friday, that may be a sign that BP is starting to win, he said. That "may in fact mean that there's mud coming up and mud coming down as well," which is better than oil coming out, Wood said.
Philip W. Johnson, an engineering professor at the University of Alabama, said the camera appeared to show mostly drilling mud leaking from the well Friday morning, and two of the leaks appeared a little smaller than in the past, suggesting the top kill "may have had a slight but not dramatic effect."
But Bob Bea, a professor of engineering at University of California at Berkeley who has studied offshore drilling for 55 years, said late Friday that what he saw didn't look promising.
He likened the effort to pushing food into a reluctant baby's mouth - it only works if the force of the stuff going down is more than the force of what's coming up.
"It's obvious that the baby's spitting the baby food back" because the pressure pushing up from the well is stronger, Bea said.
Meanwhile, President Barack Obama visited the coast Friday to see the damage as he tried to emphasize that his administration was in control of the crisis, which began April 20 when the Deepwater Horizon drilling platform blew up and killed 11 workers.
Mr. Obama saw evidence of the gushing oil on a beach near Grand Isle, La.
"This isn't just a mess that we've got to mop up. People are watching their livelihoods wash up on the beach," said Mr. Obama.
"I'm here to tell you that you are not alone, you will not be abandoned, you will not be left behind," he told people in Grand Isle, where the beach has been closed by gobs of oil and the frustration and anger are palpable. "The media may get tired of the story, but we will not. We will be on your side and we will see this through."
He also urged the public to volunteer to join the cleanup and for tourists to help by visiting the majority of the region's coastline that is untouched.
Hundreds of workers hit the beaches ahead of Mr. Obama's visit, cleaning debris from the shoreline before they hopped on buses and left soon after the president arrived.
"This is the cleanest I've ever seen the beach," Louisiana Gov. Bobby Jindal said. "We saw a surge of activity the last couple of days. Let's hope it continues now that he's gone."
The top kill operation began Wednesday, with BP pumping heavy drilling mud into the blown-out well in an effort to choke off the source of the spill which has released anywhere from 18 million gallons to 40 million gallons of oil by the government's estimate.
Coast Guard Adm. Thad Allen said the denser-than-water mud had pushed down the oil and gas that's forcing its way up from underground, but the mud had not overwhelmed the gusher.
BP has brought in about 2.5 million gallons of drilling mud for the top kill. BP chief operating officer Doug Suttles said Friday the procedure was going basically as planned, though the pumping has stopped several times.
"The fact that it's stopped and started is not unusual," Suttles said. "We're going to stay at this as long as we need to."
He said the company has also shot in assorted junk, including metal pieces and rubber balls, which seemed to be helping to counter pressure from the well. The first infusion of junk was Thursday evening.
A top kill has never been attempted 5,000 feet underwater, and public fascination is high.
BP, under pressure from Congress, made available a live video feed of what is going on underwater, and about 3,000 websites were showing a version of it that the PBS "Newshour" offered for free. On Thursday alone, show spokeswoman Anne Bell said, more than a million people watched it. Many found it hypnotic.
"It made me wonder how I use energy and if this situation could teach us how much energy we use ourselves," said Jeb Banner, 38, a web design and marketing company owner in Indianapolis who has been looking at the feed every hour or so since before the top kill started. "It felt like a historic moment."
BP says the best way to stop the oil for good is a relief well, but it won't be complete until August. The company had been drilling a second relief well as a backup - Mr. Obama said Thursday his administration pushed for it in case the first one did not stop the oil - but work on that has stopped while the rig that had been drilling it works on another option for stopping the oil.
"We actually started that well before this job started, so you shouldn't read that as any indication of anything about the top kill job," BP's Suttles said Friday.
Billy Ward, a developer who was building a gated fishing community that is now on hold because of the spill, said that Mr. Obama's visit was for show and that there was really nothing the president could do.
"It's the unknown that's killing us," said Ward, who comes to Grand Isle with his family every weekend to stay in their beach house. "We don't know if it's going to be six months or six years before we get back to normal, if ever. All we can do is pray."

Makes one wonder with the choke and kill path's if the apparatus is just damaged or faulty because of the event or whether there is always this risk. From a completely ignorant standpoint, it would seem that the choke is to apply enough perpendicular force to mix and make theflow more viscous, and the kill would be enteringa different proximity once the flow is slowed.
I would be interested to understand how much of the process is slurry dynamics and how much of the apparatus is purely mechanical.
Makes one wonder if a more dense or massive or wider cement or "mud" plug strategically could stop the flow temporarily enough to control it. Of course, I feel foolish tospeculate, just with little "petro" engineering experience.
The other thingthat I have wondered is: What is just below the BOP apparatus, belowe the sea floor? How long does the well extend? Could not perpendicular force be applied below the surface to squeeze or crush the well toeither slow of stop the floor? In other words, why cannot the focus be just below wheretheyare trying top kill?
I am a Control Systems Engineer, Process Eng Experience, not mechanical so I'm just wondering.
You are lying again. I heard the show where he "reportedly" said that. It wasn't anything like that at all. More left-wing spin. He said he would look into getting his healthcare elsewhere. He never mentioned moving. And we're supposed to believe you listen to the Rush Limbaugh show? Get real.
Sorry sweetie but I heard it with my own ears. Quote " I will leave this country if the healthcare bill is passed". Unquote. YOU are lying, as he did, but that is what hypocrites do, and do so very well. Irregardless, he is still a dope addict, as well as mouthy and arrogant. Let's not forget that, as well as his hypocrital employment of his ILLEGAL ALIEN housekeeper! You know; the one that was supplying his grug habit!!!!! WHATCH'A GOT NOW, MORON????????????????
It seems that the pressure would keep anything from falling into the hole no matter how heavy.
by generey - "He aired, several times, that he would leave the country if the healthcare bill passed."
Apparently you get your information from the Daily Kos and other such places. Rush never said this. That makes you a liar. Go spew your hate somewhere else.
Uh, excuse me poop for brains, I heard him say it. And it's not hate in general, it's hate for hypocrites. Go play with yourself.
If they could connect to the valves on the blowout preventer stack to attach the pipe to pump mud into the flow of oil, why cant they attach to the hydraulic lines that operate the pipe rams? Are the pipe rams of a different circumference than the pipe protruding from the BOP? Would it be possible to remove one of the rams in the stack and use this opening to cut off the pipe inside of the stack through the opening from the ram? Then perhaps if there is a blind ram on the stack above the cutoff, it could be closed after the pulled ram is replaced.

I'm with ya Billy... I'm gonna do a special offering to Our Lady of Gated Communities.
Yes, the cloud of oil is about 300 feet thick in some places and it is miles across and is buoyant at 1,000 feet below the surface.
The fact that it is buoyant at 1.000 feet of depth suggests that it's contact with the ocean floor will be made at 1,000 feet and remain at that depth as it crawls on the floor at 1,000 feet of depth. It will not climb to 15 feet of depth and invade Mobile Bay as many fear. In fact, this oil won't change depth until it cools, and then, it will sink deeper.
I remember that additive in California...MTBE...we were told by the oil companies it was safe, but a scientist alarmed the public who was called a disgruntled ex employee. He was right. MTBE polluted the ground and the California taxpayer was left holding the bill as big oil walked free.
