Note: *The Utica Region in eastern Ohio, one of the fastest growing natural gas production areas in the United States, has been added to the Drilling Productivity Report (DPR). Total natural gas production in the Utica Region, which includes production from the Utica and Point Pleasant formations as well as legacy production from conventional reservoirs, has increased from 155 million cubic feet per day (MMcf/d) in January 2012 to an estimated 1.5 billion cubic feet per day (Bcf/d) in October 2014.

The Drilling Productivity Report uses recent data on the total number of drilling rigs in operation along with estimates of drilling productivity and estimated changes in production from existing oil and natural gas wells to provide estimated changes in oil and natural gas production for seven key regions. EIA's approach does not distinguish between oil-directed rigs and gas-directed rigs because once a well is completed it may produce both oil and gas; more than half of the wells produce both.

While shale resources and production are found in many U.S. regions, at this time EIA is focusing on the seven most prolific areas, which are located in the Lower 48 states. These seven regions accounted for 95% of domestic oil production growth and all domestic natural gas production growth during 2011-13.
