Oil from the big spill in the Gulf of Mexico is starting to turn up in places people did not expect.
That’s making it tough for cleanup crews to stay one step ahead of the oil.
Shawn Allee reports some scientists hope supercomputers might help.

Scientists want to put together a 3D picture of what the gulf oil plume looks like, and they’re using new computer code and supercomputers to do it.

The numbers are getting crunched at Argonne national laboratory outside Chicago.
Pete Beckman runs the computing center there.

He says satellites and water samples give us some information, but we could really use a more complete picture.

“If we know for example that, because of eddies and currents, that things will accumulate at a particular map location, well, that’s where you would send the booms to soak up the oil. If you can concentrate your resources in one place, you’re much more effective.”

Beckman says even with some of the fastest computers in the world, the model of the spill could take days to finish.

Shareholders Press Big Oil for Risk Information

Several investors’ groups want four major oil companies to reveal the risks of getting oil from Canadian tar sands. Rebecca Williams reports shareholders will be considering this at BP’s general meeting this week:

Tar sands are kind of like they sound: they’re sand or clay soaked in oil. Canada’s tar sands are the second largest oil reserves in the world, so oil companies are all over them. But it’s a dirtier source of oil.

Several investors groups have filed shareholder resolutions with BP, Conoco-Phillips, Shell, and Exxon-Mobil. They want companies to reveal the risks to stockholders of getting oil from tar sands.

Emily Stone is with Green Century Capital Management.

“We want these companies to be more forthright about what they see as the big risks and how they’re mitigating those risks.”

She says risks include dealing with pollution… and lawsuits from native tribes that live near the oil sands.

BP did not want to be recorded for this story. But in a statement to shareholders, BP told them to vote no. BP says Canada’s oil sands are a proven and secure source of oil.

Tar Sands Get Tripped Up

American gasoline refineries are
expanding to process a dirtier kind
of oil. Shawn Allee reports
one company’s plans hit a snag:

The BP fuel refinery in Northwest Indiana wants to process more Canadian tar sands oil.
Processing tar sands crude creates more air pollution than normal. The federal
government wants more air pollution figures from BP before signing off on an air
permit.

Groups like the Natural Resources Defense Council pressed the government to step in.
The NRDC’s Ann Alexander is glad BP’s tar sands project is getting scrutiny.

“If tar sands are going to be developed, we think it’s it’s critical they be developed in
a way that complies with the Clean Air Act, because the Clean Air Act is there to
make sure it’s not the community that pays for development of tar sands through
increased pollution and the health problems that result, but that it’s BP who pays
those costs.”

BP’s tar sands oil project in Indiana is just one of several going on in the Midwest.
