| Abstract |
Daghestan is located on the northwestern coast of the Caspian Sea. It is a complex nonvolcanic area. A total of 51 geothermal reservoirs have been found within the border of the Daghestani Republic. Thermal water temperatures depend on the depth of drill holes (DH) and fluctuate within the range of 50 to 200°C. High temperature brines are produced from reservoirs associated with regional faults. Prognosticated up to 80°C water resources are about 180,000 cu m daily; those of high temperature waters (T>100°C) reaching 500,000 cu m daily. At present 12 min cu m per day are used for space and domestic water heating, for greenhouse heating, and in balneology. The problems of developing geothermal energetics are connected with drilling DHs, chemical activity of geothermal brines, and ecology. |
