Michael T. Klare calls unconventional oil, "tough oil"

The New “Golden Age Of Oil” That Wasn’t By Michael T. Klare: "Shale oil, for instance, is oil trapped in shale rock. It can only be liberated through the application of concentrated force in a process known as hydraulic fracturing that requires millions of gallons of chemically laced water per “frack,” plus the subsequent disposal of vast quantities of toxic wastewater once the fracking has been completed. Oil shale, or kerogen, is a primitive form of petroleum that must be melted to be useful, a process that itself consumes vast amounts of energy. Tar sands (or “oil sands,” as the industry prefers to call them) must be gouged from the earth using open-pit mining technology or pumped up after first being melted in place by underground steam jets, then treated with various chemicals. Only then can the material be transported to refineries via, for example, the highly controversial Keystone XL pipeline. Similarly, deepwater and Arctic drilling requires the deployment of specialized multimillion-dollar rigs along with enormously costly backup safety systems under the most dangerous of conditions."
