The Gallup/McKinley area has been the site of oil, natural gas, and coal production since 1927.

All production to date has been obtained from the Chaco Slope of the San Juan Basin in the northeast part of McKinley County. A cumulative total of 27.5 million barrels of oil and 6.9 billion cubic-feet of gas have been produced. High potential exists for energy resource development and supportive business industry in the Gallup/McKinley area.
