Natural Gas Shales

New drilling and well stimulation methods have produced an explosion of new natural gas activity.

Background - Gas Shales

The first commercial natural gas well in the United States was drilled in 1821 in Fredonia, New York. It produced gas from organic-rich Devonian-age shale. Since then many other wells have produced natural gas from shale. However, shale is most commonly thought of as a natural gas source rock rather than as the target of drilling activity.

In the late 1990s improved drilling and well stimulation methods were developed for the Barnett Shale of Texas which significantly increased the yield and recovery rate of natural gas from a shale. These methods are now being applied in many parts of the United States. The result has been nothing less than a boom in natural gas leasing and production activity. The maps on these pages connect you to information about several of the new gas plays.
