BP: No signs of underground leak
BP says it is encouraged by early results from the latest cap on the Gulf well. At this time there is no sign of an underground leak.
Over the next two days, BP will take regular pressure readings.
A drop might indicate that oil is leaking somewhere else, such as the piping far below the wellhead.
After the test, it's not clear yet if the oil will remain bottled in the cap, or whether BP will choose to use the new device to funnel the crude into four ships on the surface.
Meanwhile, work continues on the two relief wells, which will be used to plug the well for good.
