North American shale plays by location and maturity

Key US shale plays:

•       Barnett Shale in Texas, dry and wet gas zones, combo area with oil/condensate as well

•       Fayetteville Shale in Arkansas, mainly dry gas

•       Haynesville Shale on the Louisiana-Texas border, mainly dry gas

•       Marcellus Shale in Appalaichia, covering multiple states with Pennsylvania as main state, NE-part dry, SW-part with wet gas area

•       Bakken Shale, hybrid shale system with mainly oil production, also exploiting underlying Three Forks tight sands formation.

Emerging plays:

•       Eagle Ford in South Texas, oil and wet gas in addition to dry gas

•       Niobrara in the Rockies, mostly oil

•       Avalon in the Permian, mostly oil
