Has BP Stopped the Leak?

By Niraj Chokshi

The oil company says the Gulf leak has been stopped for the first time since April, though as yet there are no guarantees that the flow will be permanently cut off. BP is a few hours into a test of a new well cap; that test could last between six and 48 hours, MSNBC reports, citing a BP press release:

"Although it cannot be assured, it is expected that no oil will be released to the ocean during the test. Even if no oil is released during the test, this will not be an indication that oil and gas flow from the wellbore has been permanently stopped."
The cap is a stopgap measure designed to keep the oil in the well or funnel it to ships until the relief well is done. It is considered the best hope yet of stopping the crude from streaming into the water for the first time since the April 20 explosion on the Deepwater Horizon rig that killed 11 people.
