I think that it was yesterday or the day before when I heard that BP announced the pipe it had inserted was picking up 20% of the oil coming from the pipe. Assuming they're still working with that 5000 barrel a day estimate that means their pipe was picking up 1000 barrels.

Based on the estimates in this article that just doesn't seem like much of a solution.

"The latest video footage of the leaking Deepwater Horizon oil spill in the Gulf of Mexico show that oil is escaping at the rate of 95,000 barrels — 4 million gallons — a day, nearly 20 times greater than the 5,000 barrel a day estimate BP and government scientists have been citing for nearly three weeks, an engineering professor told a congressional hearing Wednesday.

The figure of 5,000 barrels a day or 210,000 gallons that BP and the federal government have been using for weeks is based on satellite observations of the surface. But NASA’s best satellite-based instruments can’t see deep into the waters of the Gulf, where much of the oil from the gusher 5,000 feet below the surface seems to be floating.

...Steve Wereley, an associate professor of mechanical engineering at Purdue University, earlier this month made simple calculations from a video BP released on May 12 and came up with a flow of 70,000 barrels a day, NPR reported last week. Werely on Wednesday told a House Commerce and Energy Committee subcommittee that his calculations of two leaks that show up on videos BP released on Tuesday showed 70,000 barrels from one leak and 25,000 from the other.

He said the calculation could be off by 20 percent — meaning the spill could range from between 76,000 to 104,000 barrels a day. But Wereley said he would need to see videos that were not compressed and showed the flow over a longer period so that it would be possible to get a better calculation of the mix of oil and gas from the wellhead."
