Conference Paper: Current Status of Geothermal Development in Romania


Exploration for geothermal resources began in Romania in the early 1960’s. Over 250 wells, drilled to depths between 800 and 3,500 m, showed the presence of lowenthalpy geothermal resources (40-120°C). Completion and experimental exploitation of over 100 wells during the past 25 years has enabled evaluation of the exploitable available heat from these geothermal resources. Proven geothermal reserves in Romania are currently about 200,000 TJ for 20 years. The main Romanian geothermal resources are found in porous and permeable sandstones and siltstones or in fractured carbonate formations. The total thermal capacity of the existing wells is about 480 MWt (for a reference temperature of 25°C). Of this total, only 145 MWt are currently used, from 96 wells (of which 35 wells are used for balneology and bathing) that are producing hot water in the temperature range of 45-120°C. For 1999, the annual energy utilisation from these wells was about 2,900 TJ, with a capacity factor of 0.62. More than 80% of the wells are artesian producers, 18 wells require anti-scaling chemical treatment, and six are reinjection wells. The main direct uses of the geothermal energy are: space and district heating 39.7%; bathing 32.2%; greenhouse heating 17.1%; industrial process heat 8.7%; fish farming and animal husbandry 2.3%. During 2005-2007 Foradex drilled

3 wells, 2 of them in E and SE-Bucharest, and one in Covasna County.
