Our current position abounds with ‘failures of perception’, unconventional sources of oil and estimates of the ‘net useful energy’ they will deliver being one of the most lethal ones.
……………….petroleum industry’s estimate that a ton of shale would yield 25 gallons of shale oil to hone their conclusion, Vanden Berg said.
Even so, it’s all theoretical. “It’s an in-place resource,” he said. “That’s very different from a recoverable resource.”
The U.S. Bureau of Land Management likewise acknowledges Western shale-resource estimates aren’t based on reality. But the agency had to include some number in its recently completed environmental study, Washington, D.C.-based BLM spokeswoman Heather Feeney said in February.
“Right now, there is no technologically or economically viable way to recover oil shale,” Feeney said. “In this particular geological formation, it’s difficult to determine exactly what portion is recoverable.”
To calculate the amount of Utah shale oil that could be recovered economically, there would have to be a technology that works here because every deposit is different, Vanden Berg said. “A technology that works in Brazil is not necessarily going to work here.”………………….
