Geothermal Exploration Methods
A geothermal reservoir causes inhomogeneity in the physical properties of the subsurface geology due to the high changes in temperature. These physical properties can be ob‐ served by means of varying anomalies from geophysical observations from the surface. These physical properties include electrical conductivity, rock density, magnetic suscepti‐ bility, rock elasticity, and, finally, the tem...
متن کاملApplication of Geochemical Methods in Geothermal Exploration
Subsurface waters have been classified into meteoric water, ocean water, evolved connate water, magmatic water and juvenile water. Geothermal water is mostly meteoric and oceanic water although andesitic waters near subduction areas often contain significant proportions of evolved connate and magmatic waters. Geothermal waters have been classified with respect to their anion and cation contents...
متن کاملMagnetotelluric Method Applied for Exploration of Geothermal Resources in Sumatra
Pertamina has conducted geothermal exploration in Sumatra showing that the depths to the top of most of the geothermal reservoirs are about 1000-2000 meters. Previous geophysical exploration work by Pertamina emphasized the use of DC-resistivity methods such as the Schlumberger method. However, these techmques can typically only penetrate to a depth of less than 1000 meters and are too shallow ...
متن کاملCost-effective Vegetation Anomaly Mapping for Geothermal Exploration
Vegetation anomalies are sometimes found over hydrothermal convection systems, where they form because of mineralization, anomalous soil gas, heat, and/or other abnormal conditions. These anomalies are often difficult to delineate without expensive biogeochemical or hyperspectral surveys. This study uses inexpensive Landsat Thematic Mapper (TM) data to delineate vegetation anomalies potentially...
متن کاملcurie depth, geothermal exploration, iran, kerman, satellite magnetic field model.
in this paper an indirect method is presented to detect potential geothermal sites in kerman province, southeast iran. geothermal heat flux is one of the main parameters to be investigated in geothermal exploration programs. however, few direct heat flux measurements are available for iran. given the proved relation between curie depths and heat flux, magnetic data can be used to calculate the ...
