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 six 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.
