Geothermal Energy in Iceland
Due to Iceland’s location on the Mid-Atlantic ridge, the island is provided with a great amount of geothermal energy. Hence, Iceland is well on the way to becoming completely independent of fossil fuels. Whereas high-temperature areas are mainly used for electricity generation, the more frequent low-temperature areas are utilized for direct application like space heating, bathing and greenhouse...
متن کاملapplication of magnetotelluric method in exploration of geothermal reservoirs with an example from iceland
magnetotellurics (mt) is a geophysical passive technique for exploring geothermal reservoirs. it utilizes a broad spectrum of natural geomagnetic fields for electromagnetic induction in the earth. this method is also preferred over dc-resistivity methods, particularly where the exploration of subsurface deep aquifers is considered. the role of mt method in the exploration of geothermal reservoi...
متن کاملGeothermal 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 کاملApplying the Hengill Geothermal Reservoir Model in Power Plant Decision Making and Environmental Impact Studies
Growth in geothermal power production in the Hengill area of Iceland, and a need for environmental impact studies that look hundreds of years ahead, has resulted in new challenges for numerical model developers. An existing, large-scale, iTOUGH2based 3-D reservoir model of the Hengill volcano has recently been recalibrated and used to study the impact of 400 MWe and 700 MWt cogenerations in two...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
