New, Cheaper Method for Shale Oil

A Technology Review article on a new method to draw oil out of shale:

A new ceramic-composite material that can withstand high temperatures and
constant exposure to moisture could provide an economical way to unlock
America's vast oil-shale deposits.

U.S. oil-shale resources hold three times as much crude oil as the whole of Saudi Arabia. But unlike with the gushing fields of the Middle East, extracting oil from shale is like trying to squeeze juice out of frozen lemons. Traditionally, the shale has been surface mined like coal and heated until an oil-like substance called kerogen turns to liquid and oozes out. But this is an expensive, energy-hungry, and carbon-intensive approach that, like much of the extraction happening in Canada's controversial oil sands, is also devastating to the local environment. More recently, companies such as Royal Dutch Shell have developed ways to tap the oil in situ, by drilling boreholes that are thousands of feet deep and feeding into them inch-thick cables that are heated using electrical resistance and that literally cook the surrounding rock. The
kerogen liquefies and gradually pools around an extraction well, where the oil-like fluid can easily be pumped to the surface.

The process involves no mining, uses less water than other approaches, and doesn't leave behind man-made mountains of kerogen-sapped shale. And according to a Rand Corporation study, it can also be done at a third of the cost of mining and surface processing. One technical hitch, however, lies with the heater cable employed. The most common cables used today are insulated with a layer of magnesium oxide, which can deform, degrade, and ultimately short out over time under intense heat, constant exposure to moisture, and the occasional shifting of rock at great depths. Replacement and maintenance can be costly.

Interior Department Shoots Down U.S. Shale

Extracting oil from shale rock is in need of further research: to better extract oil from shale, to greatly reduce the water (how much water is in Colorado?) necessary to process oil from shale, and to greatly reduce environmental damage. Still, it's worth mentioning this recent decision by the Interior Department:

Institute for Energy Research (IER) president Thomas J. Pyle issued the following statement today after the Interior Department announced its plans to withdraw from consideration acreage in Colorado, Utah and Wyoming where research and development of a small portion of our nation’s homegrown oil shale reserves had previously been scheduled to take place:

“Earlier this week, Secretary Salazar suggested America’s massive and homegrown reserves of oil shale held ‘great potential.’ Unfortunately, the Interior Department’s decision today may help ensure that potential never becomes reality – in the process, locking-away an American energy resource larger than the total reserves of the entire Middle East.

“At a time of great economic uncertainty, with millions of Americans but of work and state budgets stretched beyond their breaking point, responsible development of America’s abundant shale resources could be a way out of our current condition, and a way back to a better one. The Interior Department’s announcement today effectively forecloses that opportunity.”
