BP's Gulf well holds enough oil to spew out for two years, claim experts, Guardian, June 18, 2010:
"I would assume that 500m barrels would be a more likely estimate," said Tadeusz Patzek, the chairman of the department of petroleum and geosystems engineering at the University of Texas at Austin. "I don't think you would be going after a 50mbarrel reservoir so quickly. This is just simply not enough oil to go after."
BP spokesmen said that Barton was referring to recoverable oil rather than the total size of the reservoir.
