Geothermal Energy

Power Plant, Geothermal

The geothermal exploration does involve the search for active agricultural areas with the intention of building the geothermal power plants. The mining methods do involve several techniques which range from the drilling process into the geochemical analysis.

The geochemical analysis involves the analysis of connections between surface fluid properties into geothermal bodies. Geothermometers and other complex devices are used to gauge the subsurface temperatures. From the geochemical analysis for geothermal exploration, temperature, the ratios of isotopes, elemental ratios (for example, mercury and carbon dioxide), etc are a few of the significant measurements being made.

In the magnetic way of exploration of geothermal energy, identification of the thickness of the Curie point or Curie temperature is the main measurement.

The majority of the geological materials are non-conductors of power and so have high resistivity but the structural characteristics can boost their conductivity. Such transformation in conductivity does facilitate the mapping and so the composition of the subsurface lithology The magnetotellurics measurements facilitate the identification of resistivity anomalies related to the geothermal structural features like faults. Such measurements would result in an evaluation of geothermal reservoir temperatures at several depths. This method was successfully employed for the detection of geothermal energy in a number of states and particularly around the ring of fire.

The resistivity methods are also being extensively utilised to explore the renewable energy resources.

The gravity method is usually utilized to identify the subsurface density anomalies. Such measurements would be helpful to find the geothermal regions. The aerial gravitational techniques are more efficient in the collection of information. The gravity data must be adjusted for altitude, latitude, etc..

These regions are usually characterized by low magnitude earthquakes. Hence, further studies in these locations might provide clues to the identification of renewable energy websites.

The drilling procedure is among the most expensive but can provide reliable information regarding the subsurface. The geothermal characteristics like thermal pockets, temperature gradients, etc are obtained by using several kinds of drilling methods. The most recent developments in remote sensing techniques also have been helping in the exploration of renewable energy sources.
