NEW ORLEANS – A containment cap was capturing more and more of the crude pouring from a damaged oil well in the Gulf of Mexico, but that bit of hope was tempered Sunday by a sharp dose of pragmatism as the federal government's point man warned the crisis could stretch into the fall.

The inverted funnel-like cap is being closely watched for whether it can make a serious dent in the flow of new oil. Coast Guard Adm. Thad Allen, overseeing the government's response to the spill, reserved judgment, saying he didn't want to risk offering false encouragement.

Instead, he warned on CBS' "Face the Nation" that the battle to contain the oil is likely to stretch into the fall. The cap will trap only so much of the oil, and relief wells being drilled won't be completed until August. In the meantime, oil will continue to spew out.

"But even after that, there will be oil out there for months to come," Allen said.

"This will be well into the fall. This is a siege across the entire Gulf. This spill is holding everybody hostage, not only economically but physically. And it has to be attacked on all fronts," he said.

Since it was placed over the busted well on Thursday, the cap has been siphoning an increasing amount of oil. On Saturday, it funneled about 441,000 gallons to a tanker on the surface, up from about 250,000 gallons it captured Friday.

But it's not clear how much is still escaping from the well that federal authorities at one point estimated was leaking between 500,000 gallons and 1 million gallons a day. Since the spill began nearly seven weeks ago, roughly 23 million to 49 million gallons of oil have leaked into the Gulf.

The prospect that the crisis could stretch beyond summer was devastating to residents along the Gulf, who are seeing thicker globs of oil show up in increasing volume all along the coastline.

In Ruth Dailey's condominium in Gulf Shores, Ala., floors already are smeared with dark blotches of oil, she said, and things are only going to get worse.

"This is just the beginning," she said. "I have a beachfront condo for a reason. With this, no one will want to come."

Kelcey Forrestier, 23, of New Orleans, said she no longer trusts the word of either BP or the U.S. government in laying out the extent of the spill. But it is clear to Forrestier, just coming in off the water at Okaloosa Island, Fla., that the spill and its damage will last long into the future.

"Oil just doesn't go away. Oil doesn't disappear," said Forrestier, who just earned a biology degree. "It has to go somewhere and it's going to come to the Gulf beaches."

BP chief executive Tony Hayward told the BBC on Sunday that he believed the cap was likely to capture "the majority, probably the vast majority" of the oil gushing from the well. The gradual increase in the amount being captured is deliberate, in an effort to prevent water from getting inside and forming a frozen slush that foiled a previous containment attempt.

Allen was reluctant to characterize the degree of progress, saying much more had to be done.

"We need to underpromise and overdeliver," he said.

On Sunday, BP said it had closed one of four vents that are allowing oil to escape and preventing that water intake. The company said some of the remaining vents may remain open to keep the cap system stable.

Hayward told the BBC that the company hopes a second containment system will be in place by next weekend. Allen told CBS that the oil would stop flowing only when the existing well is plugged with cement once the relief wells have been completed.

Once the cap is fully operational, if it is ultimately successful, it could capture a maximum of 630,000 gallons of oil a day.

Besides installing the containment cap, BP officials have said they want a second option for siphoning off oil by next weekend. The plan would use lines and pipes that previously injected mud down into the well — one of several failed efforts over the past six-plus weeks to contain the leak — and instead use them to suck up oil and send it to a drilling rig on the ocean surface.

BP also wants to install by late June another system to help cope with hurricanes that could roar over the site of the damaged well. When finished, there would be a riser floating about 300 feet below the ocean's surface — far enough below the water so it would not be disturbed by powerful hurricane winds and waves but close enough so ships forced to evacuate could easily reconnect to the pipes once the storm has passed.

None of these fixes will stop the well from leaking; they're simply designed to capture what's leaking until the relief wells can be drilled.

Since the Deepwater Horizon rig exploded 50 miles off the coast of Louisiana on April 20, killing 11 workers, BP PLC has tried and failed a number of efforts to contain the leak. In the past week, increasing quantities of thick oily sludge have been making their way farther east, washing up on some of the region's hallmark white-sand beaches and coating marshes in black ooze. An observation flight spotted a sheen of oil 150 miles west of Tampa, but officials said Sunday they didn't expect it to reach western Florida any time soon.

Already, cleanup crews along the coast were struggling to keep pace with oil washing up thicker and faster by the hour. The sight and smell of oil undermined any consolation offered by reports of progress at the wellhead. Instead, Gulf residents voiced frustration with the apparent holes in cleanup efforts.

At Gulf Shores, Dailey walked along a line of oil mixed with seaweed that stretched as far as the eye could see. Collecting bits of the rust-colored oil did nothing to ease her anger. Clumps of seaweed hiding tar balls make the scene appear better than it really is, she said. Pick up a piece of weed and often there's oil underneath.

"They're lying when they say they're cleaning these beaches," said Dailey, of Huntsville. "They're saying that because they still want people to come."

Eventually, workers used a big sand-sifting machine to clean the public beach, leaving it spotless, at least for a while.

But a couple miles away, workers cleaning a section of sand at a state park finished their work and left their refuse on the beach in the way of the incoming tide.

"Waves are washing over plastic bags filled with tar and oil. It's crazy," said Mike Reynolds, a real estate agent and director of Share The Beach, a turtle conservation group.

At Pensacola Beach, Fla., the turquoise waves also were flecked with floating balls of tar. Buck Langston, who has been coming to the beach to collect shells for 38 years, watched as his family used improvised chopsticks to collect the tar in plastic containers.

"Yesterday it wasn't like this, this heavy," said Langston, of Baton Rouge, La. "I don't know why cleanup crews aren't out here."

As hundreds of cars streamed through the toll booths at the entrance to the beach, a protester stood at the side of the road wearing a gas mask, lab coat, latex gloves and holding a "Drill Baby Drill" sign with tea bags hanging from the edges.

Shawn Luzmoor said he works at a local environmental lab and has been testing the oil and tar that is washing up on the beaches.

"It's not safe and it's not right what's happening out there," he said.

Allen expressed similar frustration, ordering cleanup crews to the Alabama coastline over the weekend after surveying the scene from the air. But he acknowledged the relative futility of their efforts.

"It's so widespread, and it's intermittent," he said. "That's what's so challenging about this. Everyone wants certainty. With an oil spill like this, there isn't any."

Obama, Gulf OIL

Obama Renews Push For New Energy Policy



President Obama seized on the BP oil spill Wednesday to renew a push for legislation to "fully embrace a clean energy future," including an end to tax breaks for oil companies.
Obama said his vision for a new U.S. energy policy "means rolling back billions of dollars in tax breaks to oil companies so we can prioritize investments in clean energy research and development."

In a speech at Carnegie Mellon University in Pittsburgh, Obama said the largest oil spill in U.S. history should spur the public and policy makers to pursue long-term energy policies that don't rely on fossil fuels.

He cited energy efficiency, greater use of natural gas reserves and more nuclear power plants as fundamentals to reducing U.S. reliance on oil. Obama also renewed his call for climate change legislation while conceding that the Senate currently lacks the support needed to pass a bill drafted by Sens. John Kerry, D-Mass., and Joseph I. Lieberman, I-Conn.

"The votes may not be there right now, but I intend to find them in the coming months," Obama said. "I will make the case for a clean energy future wherever I can, and I will work with anyone from either party to get this done."

The president said that the April 20 explosion of the Deepwater Horizon oil rig in the Gulf of Mexico and the subsequent oil spill highlight the "inherent risks to drilling four miles beneath the surface of the Earth, risks that are bound to increase the harder oil extraction becomes."

While Obama looked beyond the BP spill, two senators zeroed in on the oil giant.
Sens. Charles E. Schumer, D-N.Y., and Ron Wyden, D-Ore., called on the company to delay paying dividends to shareholders.

They say the company may need every penny to maintain high capital reserves to cover the rising tab for the oil spill. Published reports estimate that BP has spent almost $1 billion so far on efforts to contain the Deepwater Horizon spill.

In a letter to BP CEO Tony Hayward, the lawmakers cited an estimate by Credit Suisse Group AG that the cost could hit $37 billion if BP cannot stop the well from leaking until August, when it hopes to complete relief drilling.

"We are certainly not opposed to BP paying dividends after the well is capped, cleanup has been completed and the victims have been justly compensated," Schumer and Wyden wrote.

Drilling Process Attracts Scrutiny in Rig Explosion

An oil-drilling procedure called cementing is coming under scrutiny as a possible cause of the explosion on the Deepwater Horizon rig in the Gulf of Mexico that has led to one of the biggest oil spills in U.S. history, drilling experts said Thursday.

The process is supposed to prevent oil and natural gas from escaping by filling gaps between the outside of the well pipe and the inside of the hole bored into the ocean floor. Cement, pumped down the well from the drilling rig, is also used to plug wells after they have been abandoned or when drilling has finished but production hasn't begun.

In the case of the Deepwater Horizon, workers had finished pumping cement to fill the space between the pipe and the sides of the hole and had begun temporarily plugging the well with cement; it isn't known whether they had completed the plugging process before the blast.

British Petroleum's oil spill in the Gulf of Mexico is quickly devastating wildlife as some 955,000 liters per day is migrating toward coastlines

Regulators have previously identified problems in the cementing process as a leading cause of well blowouts, in which oil and natural gas surge out of a well with explosive force. When cement develops cracks or doesn't set properly, oil and gas can escape, ultimately flowing out of control. The gas is highly combustible and prone to ignite, as it appears to have done aboard the Deepwater Horizon, which was leased by BP PLC, the British oil giant.

Concerns about the cementing process—and about whether rigs have enough safeguards to prevent blowouts—raise questions about whether the industry can safely drill in deep water and whether regulators are up to the task of monitoring them.

The scrutiny on cementing will focus attention on Halliburton Co., the oilfield-services firm that was handling the cementing process on the rig, which burned and sank last week. The disaster, which killed 11, has left a gusher of oil streaming into the Gulf from a mile under the surface.

Federal officials declined to comment on their investigation, and Halliburton didn't respond to questions from The Wall Street Journal.

According to Transocean Ltd., the operator of the drilling rig, Halliburton had finished cementing the 18,000-foot well shortly before the explosion. Houston-based Halliburton is the largest company in the global cementing business, which accounted for $1.7 billion, or about 11%, of the company's revenue in 2009, according to consultant Spears & Associates.

Growing worries about potential lawsuits and other costs of the oil spill in the wake of its rapid spread led investors to clobber stocks of companies involved in the Deepwater Horizon well Thursday.

Halliburton fell 5.3% to $31.60 and Cameron International Corp., which built the blowout-prevention equipment that didn't stop the explosion, dropped 13% to $38.70, both at 4 p.m. in New York Stock Exchange composite trading.

The timing of the cementing in relation to the blast—and the procedure's history of causing problems—point to it as a possible culprit in the Deepwater Horizon disaster, experts said.

"The initial likely cause of gas coming to the surface had something to do with the cement," said Robert MacKenzie, managing director of energy and natural resources at FBR Capital Markets and a former cementing engineer in the oil industry.

Several other drilling experts agreed, though they cautioned that the investigation into what went wrong at the Deepwater Horizon site is still in its preliminary stages.

The problem could have been a faulty cement plug at the bottom of the well, he said. Another possibility would be that cement between the pipe and well walls didn't harden properly and allowed gas to pass through it.

A 2007 study by three U.S. Minerals Management Service officials found that cementing was a factor in 18 of 39 well blowouts in the Gulf of Mexico over a 14-year period. That was the single largest factor, ahead of equipment failure and pipe failure.

The Halliburton cementers would have sought approval for their plans—the type of cement and how much would be used—from a BP official on board the rig before carrying out their job. Scott Dean, a BP spokesman, said it was premature to speculate on the role cement might have played in the disaster.

Halliburton also was the cementer on a well that suffered a big blowout last August in the Timor Sea, off Australia. The rig there caught fire and a well leaked tens of thousands of barrels of oil over 10 weeks before it was shut down. The investigation is continuing; Halliburton declined to comment on it.

Elmer P. Danenberger, who had recently retired as head of regulatory affairs for the U.S. Minerals Management Service, told the Australian commission looking into the blowout that a poor cement job was probably the reason oil and natural gas gushed out of control.
