CNN BREAKING NEWS: BP Claims To Have Stopped Oil From Flowing Into the Gulf
NEW ORLEANS — BP says oil has stopped leaking into the Gulf for the first time since April.
BP has been slowly dialing down the flow as part of a test on a new cap. Engineers are now monitoring the pressure to see if the busted well holds.

NEW ORLEANS (AP) — BP engineers were back to the slow work of trying to choke the Gulf of Mexico oil gusher Thursday with an untested cap, slowly dialing down the flow.
The latest step — just like other developments in the monthslong environmental crisis will take several hours to complete. If it works, BP believes no oil will be leaking into the water for the first time.
Engineers got to work after replacing a leaky pipe. Kent Wells, a BP PLC vice president, said at a news briefing in Houston that the leak was found on the side of the towering, 75-ton capping stack and it was fixed by replacing the assembly, called a "choke line."
The work sent the oil giant back to restarting preparations for testing whether the cap can stop the oil without blowing a new leak in the well. If it works, the cap will be a temporary fix until BP can drill into the gusher to plug it for good from underground, where the seal will hold better.
"Bear with us," Wells said.
With the disaster nearly three months old, the man in charge of the $20 billion fund set up by BP to pay individuals and business for their losses said it will start making payments in early August.
Ken Feinberg, who was in charge of the compensation paid to families of victims in the Sept. 11 terrorists attacks, told a meeting of government officials in Louisiana that he expected a seamless transition from BP management of claims to his administration.
On the Gulf seabed, the leak was discovered after two of the three valves on the cap that can open or shut the device had been closed, bringing BP and government scientists, who are also watching, tantalizingly close to starting a 48-hour test of how the well and cap withstand the pressure.
Wells had warned that the process of getting ready and then choking the oil a mile below the sea, at a depth only submarine robots can reach, consisted of many precise, individual steps.
"Any one of these steps can take longer than anticipated,
Retired Coast Guard Adm. Thad Allen, the Obama administration'
"I have a high degree of confidence we can substantially decrease the oil coming into the environment,
The cap remains a temporary fix, he said, until one of two relief wells BP is drilling can reach the gusher underground and plug it permanently with heavy drilling mud and cement.
"Make no mistake, the number one goal is to kill the well ... to stop it at the source," he said.
The test will involve closing off all three openings in the cap to the Gulf, in theory stopping the oil leaking into the Gulf. BP will be monitoring pressure under the cap. High pressure is good, because it shows there's only a single leak. Low pressure, below 6,000 pounds per square inch or so, could mean more leaks farther down in the well.
BP expects to keep the oil trapped in the cap for 48 hours before it decides if the approach is working.
With the leaking pipe replaced, BP had to start from a few steps back to resume preparations for the test.
Preparations included letting more oil pour out of the cap temporarily and turning off a pipe that had been sending some of the oil to a collection ship, so that the full force of all the erupting crude would go into the cap. Engineers also had to recheck equipment and move undersea robots that perform the work back into position.
Wells was hesitant to give a firm timeframe for when the test could start, but expected it to be Thursday.
"We're going to keep moving forward with this," Wells said.
Allen said a committee of scientists and engineers will monitor the results and assess every six hours, and end the test after 48 hours to evaluate the findings.
"I was gung-ho for this test and I remain gung-ho for this test," he said Wednesday.
If the cap works, it will enable BP to stop the oil from gushing into the sea, either by holding all the oil inside the well machinery like a stopper or, if the pressure is too great, channeling some through lines to as many as four collection ships.
Allen said the testing will also help prepare for the hoped-for permanent fix by the relief wells. The mapping of the sea floor that was done to prepare for the cap test and the pressure readings will also help them determine how much mud and cement will be needed to seal off the well underground.
Drill work was stopped on one relief well because it was not clear what effect the testing of the cap could have on it. Work on the other relief well had already been stopped according to plan.
The government estimates 1.5 million to 2.5 million gallons are leaking every day.
As of Thursday, the 86th day of the disaster, between 93.5 million and 184.3 million gallons of oil had spewed into the Gulf since the Deepwater Horizon rig leased by BP exploded April 20, killing 11 workers.
