Renewable Energy - Geothermal

 

HDL provides exploration management and geological research of geothermal resources.  We are  are currently working for the U.S. Department of Energy  on developing a new method, Fluid Inclusion Stratigraphy (FIS), which is based on measuring the gas concentrations trapped within minerals for evaluating the hydrological regime in geothermal reservoirs. This low cost and rapid logging method can be used as the well is drilled to determine if hot reservoir fluids have been encountered and if permeable zones exist in the well.  The US Navy has recently contracted with us to apply this technique to a number of their new prospects.  In addition we are managing the reconnaissance of Tenakee Inlet geothermal prospect.  This has included conducting the geological field studies, collecting soil and water samples for geochemical analysis, and interpretation of the results.
