This report contains the final technical analysis of the Project Independence Interagency Natural Gas Task Force chaired by the Federal Power Commission. The task force was formed in April 1974 to provide estimates of the potential production capabilities of the natural gas industry and the resources necessary to achieve these levels of production. The task force evaluated two alternative strategies. The first was business-as-usual, which assumed the continuation of all current policies that could affect levels of production. The second strategy, accelerated demand, assumed selected changes in policies or practices that would permit a greater expansion of potential production. The report considers what could occur with respect to non-associated natural gas from domestic sources during the period 1974 through 1990. Estimates were based on the following data: production data, price and cost data, and resource input data. Also considered in respect to increased natural gas production were environmental considerations and impacts and production constraints.
