Geophysical Studies
Geophysical exploration plays a very important role in geothermal exploration. Various physical parameters are measured, such as resistivity, density, sound velocity and magnetism of the subsurface rocks.
Resistivity surveys as carried out by Iceland GeoSurvey yield important information about the subsurface structure of geothermal systems.
The following services are offered:
-
TEM-MT measurements, processing and interpretation. Transient electromagnetic (TEM) soundings are used to map temperature distribution in the uppermost 1 km of the crust. Magneto-telluric (MT) methods are applied to detect up-flow of thermal fluid into the reservoir.
- Seismic surveys, processing and interpretation.
- Seismic monitoring. Monitoring of seismic activity shows fracture zones at depth.
- Gravimetric measurements. Gravity surveys may reveal tectonic features in the reservoir.
- Surface GPS measurements
