Assessment

The ATLAS Team has a long record of experience in assessment of geothermal systems in a variety of geologic settings and countries.  The papers listed below provide examples of the types of work in which the team has expertise in assessing geothermal systems.

The photo shows different types of fluid deposits at the Salt Wells geothermal system, Nevada used to assess variations in fluid temperatures and discharge locations over time to form the various deposit types.
