1. Pertaining to geothermal systems involving solid rock with insufficient permeability for fluids.
   • 1989, Science & Technology in the Islamic World:

     In petrothermal resources most of the heat is stored in the rock mass, while in hydrothermal resources pore fluids carry a substantial fraction of the total energy in situ.

   • 1993 April 3, Richard C. Dorf, Electrical Engin Hdbk The, CRC Press:

     Some fields have only hot rocks under the surface. Utilization of this petrothermal source requires pumping surface water through a well in a constructed hole to a reservoir.

   • 2022 April 21, Johanna Fink, Elisa Heim, Norbert Klitzsch, State of the Art in Deep Geothermal Energy in Europe: With Focus on Direct Heating, Springer Nature, →ISBN, page 9:

   • 2022 June 16, Mejdi Jeguirim, Renewable Energy Production and Distribution: Recent Developments, Academic Press, →ISBN, page 273:

     It is, for example, estimated that the theoretical potential for electricity generation from petrothermal reservoirs in Germany is about 1100 EJ [2], which means that the resource could have a significant share in the energy supply from renewable energies (RE) in the future.
