Gulf oil may be double earlier estimates

The new figures could mean 42 million to 84 million gallons of oil have leaked into the Gulf of Mexico since the Deepwater Horizon rig exploded on the night of April 20 — with the lowest estimate nearly four times the size of the 1989 Exxon Valdez spill.

The flow estimates were released by Marcia McNutt, director of the U.S. Geological Survey, and do not count any increases that may have occurred since the cutting of the well's riser pipe, a step that was expected to boost the flow.
