Geothermal – Subduction Zone Volcanic Arc Geology

Another potential location for accessing Geothermal Energy is Subduction Zones associated with Volcanic Arc Geology. Hydrothermal and/or petrothermal reservoirs are possible to be exploited for significant enthalpy with production and injection wells.

• Volatile fluid release from subducted  crust includes  carbon  components  from organic matter, carbonates, water  and hydrous materials.  These  fluids  rise up and some end up in deep  hydrothermal reservoirs;
• Magmatism is melted slab rock  containing many elements which  similarly rise up bringing significant  heat closer to the surface  including  into petrothermal reservoirs (fractured  hot dry rock);
• Surface heat flux is a function of Moho  temperature, magma temperature,  crustal thickness, and magma ponding levels with heat conduction through  the crust and heat advection by rising  melts;
• These hydrothermal and petrothermal reservoirs are able to be exploited with production and injection wells to capture the heat for Geothermal energy from surface Binary ORC power generation equipment.
