• Unconventional Oil & Gas

    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 Bakken, Eagle Ford, Marcellus, Fayetteville, Woodford, Niobrara, Haynesville, Horn River, and Utica formations. Tight gas, coalbed methane, oil sands, and heavy oil are non-shale unconventional resources.

    Tight Gas Sands

    Tight Gas Description ImageThe term tight gas sands refers to low-permeability sandstone reservoirs that produce primarily dry natural gas. A tight gas reservoir is one that cannot be produced at economic flow rates or recover economic volumes of gas unless the well is stimulated by a large hydraulic fracture treatment and/or produced using horizontal wellbores. This definition also applies to coalbed methane, shale gas, and tight carbonate reservoirs. Tight sands produce about 6 tcf of gas per year in the United States, about 25% of the total gas produced. The Energy Information Administration estimates that 310 tcf of technically recoverable tight gas exists within the US, representing over 17% of the total recoverable gas. Worldwide, more than 7,400 tcf of natural gas is estimated to be contained within tight sands, with some estimates as large as 30,000 TCF.
