Potential Gas Committee

Potential Gas Agency Colorado School of Mines

  • 100 Volunteer geoscientists & petroleum engineers
  • Biennial assessments–since 1964–of the

Technically Recoverable U.S. natural gas endowment PGC Resources + EIA Proved Reserves = Potential Future Gas Supply

Organization of Potential Gas Studies

Potential Gas Committee

Natalie H. Reagan President/General Chairman Larry M. Gring Chairman, Board of Directors

Develops assessment policy and procedures, directs and manages studies

  • f natural gas resources, recruits

personnel and supervises work, prepares reports on natural gas resources.

Potential Gas Agency

Colorado School of Mines (supported by industry)

  • Dr. John B. Curtis, Director

Approves criteria and methods, insures maintenance of standards and objectivity, reviews and evaluates reports, publishes final assessments of gas resources.
