U.S. Gas Production: Can We Trust the Projections?

Government (EIA) forecasts suffer in credibility when compared with geologic assessments.

are realized. Over the course of history, market prices and supply of natural resources have shown instabilities - instabilities that are better captured through well-thought out scenarios than through the standard types of sensitivity analysis involving a base case.

  1. Natural gas prices were gradually deregulated during the 1980s and early 1990s. Prior to this, Federal regulators had set well-head and pipeline prices and local regulators set retail prices. Although new natural gas electricity generating facilities were prohibited by the Natural Gas Policy Act of 1977, that provision of the Act was rescinded during the 1990s.
  2. Proved reserves are estimated quantities of oil and gas that geologic and engineering data demonstrate with reasonable certainty to be recoverable in future years under existing economic and operating conditions.
  3. Conventional fields consist primarily of discrete accumulations delineated by hydrocarbon/water contacts. Data for Figure 3 were provided by EIA and relate to Figure 94 in the Annual Energy Outlook 2001 (EIA, 2000).
  4. Both the EIA (2000) and the recent National Petroleum Council (NPC) study claim to use the 1995 USGS assessment as the basis for their respective forecasts of onshore production (NPC, 1999, p. 37). See Attanasi and others (1997) for the province breakdown.
  5. The Minerals Management Service recently re-assessed the undiscovered oil and gas in the Gulf of Mexico. The mean undiscovered oil was increased by 29 billion barrels of oil (Bbo) to 37 Bbo and undiscovered gas increased by 97 Tcf to 193. At well-head prices of $30 per barrel oil and $3.50 per mcf, gas about 75 percent of the gas is economic.
  6. The EIA forecast assumes no opening of any offshore area where exploration is currently prohibited.
