The analytics firm IHS released a study yesterday regarding the prospects of tight oil reserves outside of North America. They discovered that the global potential for tight oil could be as high as 500 billion barrels.
Tight oil is a petroleum play that is made up of crude oil contained in non-porous rocks such as shale. Tight oil and gas reserves have become increasingly popular in North America, as IHS recently concluded that tight oil will add approximately 94 billion barrels of recoverable oils to the reserves of this region.
