The Marcellus Shale is a geologic formation that underlies much of the Appalachian Basin in the eastern United States. It is a rich source of natural gas, and its development has had a significant impact on the region's economy and environment.
Two new animations from the U.S. Geological Survey (USGS) show the extent of Marcellus Shale development in the Appalachian Basin. The animations are based on data from the USGS's National Gas and Oil Infrastructure Data (NOGID) database.
The first animation shows the number of wells that have been drilled in the Marcellus Shale region since 2008. The animation shows that the number of wells has increased dramatically in recent years, from just a few hundred in 2008 to over 15,000 in 2015.
The second animation shows the amount of natural gas that has been produced from the Marcellus Shale region since 2008. The animation shows that natural gas production has also increased dramatically in recent years, from just a few billion cubic feet in 2008 to over 1 trillion cubic feet in 2015.
The animations provide a visual representation of the rapid growth of the Marcellus Shale industry in the Appalachian Basin. The industry has created jobs, boosted the economy, and helped to reduce the nation's dependence on foreign energy sources. However, it has also raised concerns about environmental impacts, including water pollution and air pollution.
The USGS animations provide valuable data for understanding the extent of Marcellus Shale development and its potential impacts. The data can be used by policymakers, regulators, and the public to make informed decisions about the future of the Marcellus Shale industry.
