The current posted price of $76.00 per Mcf in-kind and $106.00 per Mcf conservation Helium has increased interest in the hunt for helium. Some of the richest helium-bearing gas in the world was produced in Arizona. Helium concentrations range from trace amounts up to ten percent in the Holbrook Basin and Four Corners. Both areas have good potential for additional discovery and production of helium. This potential was the focus of the Arizona Geology published in winter 2003. Download Here  Additional reports about helium in Arizona are available online at the AZGS document repository by clicking here
