The author presented to SIPES on helium in southeastern Colorado as recently as 2022. This presentation is is an outgrowth of continued research, and is reoriented away from discussion of principles and systematics, which are well covered in the literature and were pursued at the recent RMAG Helium Conference. Instead, in this presentation I will explore the detailed geology of five or six helium occurrences in the southern Rockies that are interesting, at least to me. These examples demonstrate a variety of geological sources and traps for helium, from a giant CO2-dominated anticlinal pool in Wyoming to an active helium-bearing, but non-producing hydrothermal system in Colorado, with other occurrences thrown in for good measure.
Today’s speaker is known to many of you. Ed Coalson was schooled in geology at Cal State Long Beach and the University of Wyoming in the 1960’s. Intense re-education came in the 1970’s and 1980’s at Amoco Production Company and Davis Oil Company in Denver. A vanity Ph.D. came in 2012 from the Colorado School of Mines. After working for several Denver independent oil and gas companies, he currently provides consulting geology and petrophysics for Desert Mountain Energy, a helium-exploration company with operations centered in the Holbrook Basin of Arizona.
