Emerald Oil & Gas NL is a petroleum exploration and production company based in Perth, Australia. The Company holds interests in exploration and production operations in the USA (North Dakota, Colorado, Wyoming, Kentucky and Texas) and Western Australia.

Emerald's core assets are its unconventional oil assets in the prolific Williston Basin, Bakken/Three Forks play located in North Dakota and its large acreage holding over the Niobrara Continuous Shale Oil accumulation in Green River Basin in Colorado and Wyoming. Emerald's primary business objective is to generate maximum value for Emerald shareholders from its holdings in its unconventional shale oil resource plays. Emerald plans to use its position in these US Shale plays as a foundation on which to build an active US based oil and gas company focused in the Rocky Mountain region.
