No oil flowing into Gulf of Mexico for first time in months

There was no oil flowing into the Gulf of Mexico this afternoon after BP crews managed to shut in the leaking Macondo well. The company is now conducting a "well integrity test" to determine if the well can remain closed until it can be permanently shut with cement next month. The test will last anywhere from 6 to 48 hours, during which time scientists will measure pressure inside the well. If pressure rises and holds at 8,000 to 9,000 pounds per square inch, the well could remain closed. If it is lower than that level, however, if will be reopened and oil will be sucked, again, to vessels on the surface.
