Gulf Coast Holds Breath as BP Tests New Well Cap

Updated at 6:52 p.m. ET
After securing a new, tight-fitting cap on top of the leaking well in the Gulf of Mexico, BP prepared Tuesday to begin tests to see if it will hold and stop fresh oil from polluting the waters for the first time in nearly three months.
The oil giant expects to know within 48 hours if the new cap, which was affixed Monday after almost three days of painstaking, around-the-clock work a mile below the Gulf's surface, can stanch the flow. The solution is only temporary, but it offers the best hope yet for cutting off the gush of billowing brown oil.
The cap's installation was good news to weary Gulf Coast residents who have warily waited for BP to make good on its promise to clean up the mess. Still, they warned that even if the oil is stopped, the consequences are far from over.

"I think we're going to see oil out in the Gulf of Mexico, roaming around, taking shots at us, for the next year, maybe two," Billy Nungesser, president of Louisiana's oil-stained Plaquemines Parish, said Monday. "If you told me today no more oil was coming ashore, we've still got a massive cleanup ahead."
Kent Wells, a senior vice president at the oil giant, made no promises in a Tuesday morning news briefing about whether the cap will work.
"We need to wait and see what the test actually tells us," Wells said. "It's not simple stuff. What we don't want to do is speculate around it."
"I know that we've made some mistakes along the way but we're committed to do everything we can to earn back our reputation," he said earlier.
Starting Tuesday, the cap will be tested and monitored to see if it can withstand pressure from the gushing oil and gas. The tests could last anywhere between six to 48 hours, according to National Incident Commander Thad Allen.
First, surface ships will stop recovering oil, reports CBS News correspondent Mark Strassmann. Then engineers will close two of the stack's three valves, trapping most of the new leak inside.
Next, a robotic submarine will slowly close the final valve called a choke line. By then, no oil should escape. Sensors will measure change in the well's pressure.
"The sealing cap system never before has been deployed at these depths or under these conditions, and its efficiency and ability to contain the oil and gas cannot be assured," the company said in a statement.
BP doesn't want the flow of oil to stop instantaneously, said Don Van Nieuwenhuise, director of Professional Geosciences Programs at the University of Houston. Shutting the oil off too quickly could cause another explosion, he said.
"Rather than like a train running into a brick wall, it'll be more like putting the brakes on slowly," he said. "That's what they're aiming for. You can keep the brakes on and everyone arrives alive, or you hit the wall and have big problems."
BP will be watching pressure readings. A high reading, pounds per square inch between 8,000 and 9,000, is good, reports Strassmann. It means the well's holding up well. BP's spill could be over.
A lower reading, psi between 4,000 to 5,000, means trouble. The well's casing pipe has other weak spots and oil's escaping somewhere.
In that case, BP would add another cap, and try to divert leaking oil to surface ships, reportsStrassmann.
"Another concern right now would be how much pressure the well can take," and whether intense pressure would further damage the well, said Eric Smith, associate director of the Tulane Energy Institute.
But, "This is the elegant solution. This is the right equipment. All of the other top hats and everything have been sort-of jury-rigged solutions," Smith told Strassmann.
Even if the cap works, the blown-out well must still be plugged. A permanent fix will have to wait until one of two relief wells being drilled reaches the broken well, which will then be plugged up with drilling mud and cement. That may not happen until mid-August.
Even if the flow of oil is choked off while BP works on a permanent fix, the spill has already damaged everything from beach tourism to the fishing industry.
Tony Wood, director of the National Spill Control School at Texas A&M-Corpus Christi said the sloppiest of the oil - mousse-like brown stuff that has not yet broken down - will keep washing ashore for several months, with the volume slowly decreasing over time.
He added that hardened tar balls could keep hitting beaches and marshes each time a major storm rolls through for a year or more. Those tar balls are likely trapped for now in the surf zone, gathering behind sand bars just like sea shells.
"It will still be getting on people's feet on the beaches probably a year or two from now," Wood said.
But on Monday, the region absorbed a rare piece of good news in the placement of the 150,000-pound cap on top of the gushing leak responsible for so much misery.
Around 6:30 p.m. CDT, live video streams trained on the wellhead showed the cap being slowly lowered into place. BP officials said the device was attached around 7 p.m.
"I'm very hopeful that this cap works and we wake up in the morning and they're catching all the oil. I would be the happiest person around here," said Mitch Jurisich, a third generation oysterman from Empire, La., who has been out of work for weeks.
Residents skeptical BP can deliver on its promise to control the spill greeted the news cautiously.
"There's no telling what those crazy suckers are going to do now," Ronnie Kenniar said when he heard the cap was placed on the well. The 49-year-old fishermen is now working for BP in the Vessel of Opportunity program, a BP-run operation employing boat owners for odd jobs.
James Pelas, 41, a shrimper who took a break from working on his boat at a marina in Venice, La., said he didn't think the crisis would be over for a long time.
"I ain't excited about it until it's closed off completely," he said. "Oil's scattered all over the place."

Meanwhile, the Obama administration issued a revised moratorium on deep-water offshore drilling Monday to replace the one that was struck down by the courts as heavy-handed. The new ban, in effect until Nov. 30, does not appear to deviate much from the original moratorium, as it still targets deep-water drilling operators while defining them in a different way.
As of Monday, the 83rd day of the disaster, between 89 million and 176 million gallons of oil had poured into the Gulf, according to government estimates. The spill started April 20 when the Deepwater Horizon rig, leased by BP from Transocean Ltd, exploded and burned, killing 11 workers. It sank two days later.
