Growing and Indispenable: the Contributions of Rocky Mountain Unconventional Gas Resources and Production to U.S. Gas Reserves and Production

Production and reserve additions from unconventional gas resources have been growing and indispensable components of U.S. gas production and reserve additions. This paper first examines the contribution of each unconventional component - tight sandstones, coalbed methane, deepwater, shale gas, tight carbonates, and ultradeep gas - to U.S. gas production and reserve additions from 1990 to 2006. During this period, the share of unconventional gas production in total U.S. gas production grew from one-sixth to one-half. The particular emphasis of the paper will be on the specific contributions of unconventional Rocky Mountain gas to national production and reserve additions. These contributions have come predominantly from tight sandstones and coalbed methane. The presentation will conclude with a forecast of Rocky Mountain unconventional production and reserve additions to 2020. From 2010 to 2020, the Rocky Mountain region should be the most important region for U.S. gas production.
