Oil shale
The estimated shale oil resources of the top 12 countries together account for 99 percent of the world's total reserves and production. The "in-place resources" of each country are commonly given in oil equivalents—that is, the number of barrels or metric tons of oil that are estimated to be contained in the oil shale deposits located in that country.Web

Oil Shale
Oil Shale. John R. Dyni, in Encyclopedia of Energy, 2004 1 Introduction. Oil shale is a low-unit-cost energy commodity that requires mining and retorting thousands of tons of oil shale per year to achieve profitability. For example, one short ton of a commercial grade oil shale from the Green River formation in Colorado assays about 35 U.S. gallons of shale oil …Web
