    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.

    Barnett Shale

    Barnett Shale Description Image

    The Barnett shale in north-central Texas lies in the Fort Worth Basin. Discovered in the 1950s, the Barnett was not commercially viable until the 1980s. Some geologists believe the formation could hold 30 trillion cubic feet of natural gas. A significant part of the drilling has occurred in the Fort Worth metro area, and Chesapeake Energy actually secured rights to drill beneath the Dallas-Fort Worth International Airport.

    Drilling in the Barnett shale intensified in the past decade as modern horizontal drilling and hydraulic fracturing techniques were perfected for drilling in shale. Devon Energy, Chesapeake Energy, XTO Energy, and EOG Resources are among the larger players in the Barnett shale. Two years ago, 70% of all US gas shale production came from the Barnett, but that percentage of the total has been declining as production has risen in other plays.

    Can the shale gas rBart Willigers, Palantir Solutions Ltd. evolution currently taking place in the US be repeated elsewhere? Although significant volumes of unconventional gas deposits are present in Poland, France, Germany, Hungary, Sweden, Turkey, and the UK, shale gas developments are running many years behind their counterparts in the US. Skeptics have pointed out that differences in geology, taxes, public acceptance, environmental regulations and other factors in Europe vs. the US make for a tougher environment in which to develop unconventional resources.
