The Congressional Research Service released a report this week showing that oil and gas production has fallen on leased federal lands. From The Hill: "The report from the nonpartisan agency of Congress said oil product declined 6 percent from 2009 to 2013 on federal lands, while gas production decreased 28 percent. In that same time, crude oil production increased 61 percent on nonfederal land and gas production grew 33 percent, the CRS said in the report, which the House Energy and Commerce Committee released Wednesday."
