Source: Icelandic International Development Agency (ICEIDA), 2009 Geophysical research with Bouguer gravity measurements complement MT and TEM measurements by measuring anomalies in the density distribution of subsurface rocks, thereby permitting the identification of large geological structures whose boundaries can be associated to tectonic features that in turn may lead to faults and fractures. Results of geophysical exploration used in combination with geology can lead to the location and interpretation of the heat source. Temperature gradient holes are shallow and slim boreholes, usually <500 meters deep, drilled to measure the increase in temperature with depth. The standard temperature gradient worldwide is around 30°C per km depth, resulting in an average temperature of 90°C in 3 km depth. If, in a certain area, the temperature gradientincreased, for example, to 90°C/km , this would result in a temperature of 270°C at 3 km depth and would be promising for geothermal power generation, as long as enough steam could be extracted from the reservoir. Gradient holes also allow the collection of additional chemical samples of fluids, as far as they are available. It is common to drill three to five gradient holes as part of the exploration of a geothermal greenfield, especially in areas where no signs of recent volcanism can be found. Well known from the oil and gas business, seismic research is a geophysical research method which uses “waves” from the surface to map subsurface structures like faults and cracks, which are important because they often are the conduits for hot steam and fluids. Therefore, any drillings for geothermal would be targeted to hit at least one subsurface fault; by using directional drilling methods, it is possible to hit more than one fault and thereby further increase, even multiply, the steam or fluid production of the geothermal well. Seismic research is especially popular within sedimentary basins. The Monte-Carlo simulation method is widely used by geothermal project developers and provides a first-level risk analysis. It compares the main variables like the volumetric heat contents, based on flow rate and temperature of geothermal fluids or steam, thereby giving an idea of the probable MW capacity of a given geothermal field. The result can reveal the bottlenecks and risk factors of the projects in question and can be used for a first economic evaluation of the project. 15. size, can range from 5 to 20 percent of the total project costs. Doing MT’s, TEM’s, seismic or drilling gradient holes, depends on the accessibility of the geothermal site and the availability of tools, equipment and knowledgeable staff to operate the equipment and interpret the results. While minimum exploration costs for a geothermal site would in many cases be 1 to 2 x x x x Costs for the activities under phase 2 can be significant, and depending on the project 59
