"Technically Recoverable Shale Oil and Shale Gas Resources
estimates that shale resources considered in conjunction with EIA's own
assessment of resources within the United States indicate technically
recoverable resources of 345 billion barrels of world shale oil
resources and 7,299 trillion cubic feet of world shale gas resources. While the current report considers more shale formations
than were assessed in the prior version of this assessment, it still
does not assess many prospective shale formations, such as those
underlying the large oil fields located in the Middle East and the
Caspian region. Currently, only the United States and Canada are
producing shale oil and shale gas in commercial quantities ... These shale oil and shale gas resource estimates are highly uncertain
and will remain so until they are extensively tested with production
wells. This report's methodology for estimating the shale resources
outside the United States is based on the geology and resource recovery
rates of similar shale formations in the United States (referred to as
analogs) that have produced shale oil and shale gas from thousands of
producing wells. ... However, given the variation across the world's shale formations in both
geology and above-the-ground conditions, the extent to which global
technically recoverable shale resources will prove to be economically
recoverable is not yet clear. The market impact of shale resources
outside the United States will depend on their own production costs and
volumes. For example, a potential shale well that costs twice as much
and produces half the output of a typical U.S. well would be unlikely to
back out current supply sources of oil or natural gas. In many cases,
even significantly smaller differences in costs, well productivity, or
both can make the difference between a resource that is a market game
changer and one that is economically irrelevant at current market
prices."
