Research Objectives
Changes in CO2 content and nitrogen/argon (N2/Ar) weight ratios in the steam produced by wells from the eastern parts of the Cerro Prieto geothermal field of Baja California, Mexico, were studied to determine the effects of the main active processes in the reservoir (i.e., boiling, condensation, groundwater recharge, and mixing) on the gases contained in the steam.

Nitrogen/argon weight ratios in geothermal steam produced by eastern Cerro Preito wells for the years 1990, 1995, and 2000. The shaded area corresponds to the intersection of the main fault in the field (normal Fault H) with the top ofthe deeper reservoir (Beta Reservoir) (distances in meters).
