When President Barack Obama said in his State of the Union speech this year that the United States has a supply of natural gas that can last nearly 100 years, he was using a quick-and-dirty, back-of-the-envelope computation that is nonetheless rooted in recent geological research. Even the nation’s top petroleum geologists, who typically measure natural gas reserves in trillions of cubic feet (tcf) grudgingly admit the need to simplify — even oversimplify — their research for public consumption.
