The availability of rare earth elements from primary resources has come into question in the last two decades. This has sparked various government and industry initiatives to examine potential rare earth element resources apart from virgin ore bodies. Geothermal fluids are potentially significant sources of valuable minerals and metals, while co-recovery with geothermal energy production would ...

The utilization of geothermal energy has a long tradition in Hungary. When the present economic recession in the country ends in the near future, geothermal energy will surely play an increasing role in the energy supply. The paper shortly reviews the history of geothermal power use and discusses the present state of geothermal energy production in the country. Present power statistics as well ...

As part of the initial assessment of the geothermal power potential of Indonesia an electronic model, (IGSEP), Mahon, (1987), was developed to prioritise the most favourable resources and determine the least cost development scenarios for generating geothermal electricity. The model was tested and assessed using data from 100 different geothermal prospects in the country. This involved research...

Geothermal waters from springs and wells are currently used in eight spas and water centers in Poland. These resorts have a long and interesting history, being an important part among all the health spas in the country. The demand for geothermal curative and recreation services offered in spas constantly increases. The paper presents several cases of geothermal resorts and some examples of init...

Abstract This paper presents a Multidisciplinary geophysical study of the geothermal areas in Uzbekistan. Based on developed new map, data anomalous were analyzed. Muruntau area, comprehensive methodology has been for detailing anomalies. New integrated surveys (gravity survey, seismic magnetotelluric survey) and their interpretation at stage exploration are presented.

Renewable energy is seen as the future source for meeting the world’s growing demand, with geothermal offering a constant and independent supply. Tapping geothermal energy is not always straightforward as deep drilling is required in order to access this high -temperature resource. Geothermal drilling is expensive and is financed by the operator (usually districts or state representatives) with...

Thermal infrared imagery (TIR) is a useful tool to detect and quantify the surface temperature anomalies associated with geothermal fields. Accurate detection of anomalies in surface temperature is an important aspect of geothermal research. Although day-time TIR images have long been used for temperature anomaly mapping, the increase in the spatial resolution and the number of acquisitions of ...

A numerical model of the NW-Sabalan geothermal field was developed. The model covers a total area of 96 km and extends vertically from variable elevation of 2200-3600m a.s.l to 1,000m b.s.l. The model has 2,595 grid blocks in l4 horizontal layers. The boundary conditions and distributions of horizontal and vertical permeabilities were obtained by trialand-error matching of the initial temperatu...

in this paper, geographical information system (gis) is used as a support system for decision making in order to provide the map of high potential areas for the construction of greenhouses benefited from geothermal energy. the goal is to perform a geothermal energy resource assessment in eastern azerbaijan province as a base for further studies to achieve sustainable development objectives in t...
