Key Terms Definition

This category excludes natural gas plant liquids, such as butane and propane, which are recovered at downstream natural gas processing plants or facilities.

  • Shale production volumes are broken out separately for 2008 and 2009 but remain embedded in gas well volumes for prior years and 2010. Similarly, coalbed volumes, first broken out as a separate production category in the 2008 NGA, are included in gas well production totals for years prior to 2007 and 2010.
