Shale plays first come to mind when one considers unconventional resources. These unconventional resource plays may yield natural gas, gas condensates, and crude oil. Some of the more noteworthy shale plays in North America include the Barnett, Haynesville, Marcellus, Eagle Ford, Fayetteville, Woodford, Bakken, Niobrara, Horn River, and Utica formations. Tight gas, coalbed methane, oil sands, and heavy oil are non-shale unconventional resources.

Deloitte: Shale gas, oil potential increasingly apparent
May 21, 2013
Oil and gas production from tight shale formations clearly is a long-term phenomenon and not a short-term trend, Deloitte LLP officials told reporters. The financial services company found growing confidence in unconventional energy resources in a survey it conducted last year, said John England, a vice-chairman and leader of its oil and gas practice. |

International Unconventional
The Piceance and Uinta basins are in northeastern Utah and northwestern Colorado. Both the Piceance and Uinta are tight gas resources plays. The primary target of gas development has been the Williams Fork formation, of Cretaceous age, in the Mesaverde group. The Williams Fork is a several-thousand-foot thick section of shale, sandstone, and coal deposited in a coastal plain environment. The formation has long been known to contain natural gas. However, the sandstone reservoirs have low permeability and limited areal extent, which made gas wells uneconomic in the past.
Key players in the Piceance and Uinta resource plays include Chevron, Encana, ExxonMobil, Noble Energy, Bill Barrett Corp., Antero Resources, Delta Petroleum, Laramie Energy, and Harvest Natural Resources – to name just a few.
