Isotopic analyses of helium from wells located in the Four Corners area, southwestern US
Helium, the lightest noble gas, is a valuable resource located on the Colorado Plateau southwestern US. Helium, a proven, useful noble gas, has many applications in modern technology for its chemical, physical, and thermodynamic properties. As of this writing, the price of crude helium is ~40% greater than CH4, rendering the economic grade for direct and secondary extraction at 0.3% helium. The helium systems in the Four Corners area (i.e., the study area) are characterized utilizing the geochemistry of noble gases, hydrocarbons, and non-hydrocarbons (compositional and isotopic), as well as ...
