| Abstract [eng] |
Lithuania has a large unutilized geothermal heat production potential due to enhanced geothermal gradient (up to 42°C/km) in the SW of the country. The geothermal anomaly follows the geometry of the Middle Proterozoic “hot” granitoid intrusions rich in radiogenic heat producing elements. Additional increase in heat flow is also associated with thermal blanketing effect, where the heat is preserved in the rocks at depth due to 2 km thick sedimentary cover above the intrusions. Since the abandonment of the Klaipeda Geothermal Demonstration Plant (KGDP) in 2017 due to prevailing injection degradation issues, no new geothermal installations have been achieved in Lithuania. However, in the past 3 years research has been renewed on geothermal potential evaluations for Devonian hydrothermal complexes as well as abandoned or close to depletion Cambrian and Silurian oil fields using existing infrastructure. |
