Free Preview - WSJ.com: "The nation's frantic search for crude-oil sources is leading to one of the oldest, richest and most-elusive prizes in the petroleum industry: oil shale.
The U.S. has the largest known reserves of the coal-like rock, 80% of which lie beneath federal lands. By some estimates, U.S. oil-shale reserves could yield 800 billion barrels of oil, triple the current proven reserves of Saudi Arabia.
But tapping that potential requires heating rocks buried deep beneath the earth to hundreds of degrees Fahrenheit. Oil companies are racing to find ways to do so economically, but their solutions are years away from commercial use."
