2. Geothermal Energy Related Risk: Water Volumetric EXECUTIVE SUMMARY The growing Geothermal technology for producing alternative energy requires an answer from the insurance sector. The costs of drillings are currently a significant part of the investments for such an important goal. For that reason and due to the fact the science provides the necessary prevention technology to secure profitable operations, is that ACC Group Geothermal Energy division has developed a policy to fulfill the need of insuring the risk of not finding the right temperatures and the necessary flow of qualities waters to produce energy. Our “Water Volumetric” policy is the result of our research in this field. Hoping this is a contribution for Geothermal Energy development.

14. PLATE BOUNDARIES Earth's crust is broken into huge plates that move apart or push together at about the rate our fingernails grow. Convection of semi-molten rock in the upper mantle helps drive plate tectonics.

16. GEOTHERMAL PLANTS RISK MITIGATION Science provides the necessary studies to determine the geographical areas where a geothermal plant should be located. Before drilling geological, geochemical and geophysical data analyzed to define the drilling target. Geothermal Energy Sciences used prior to any exploration drilling:
17. - On site reconnaissance - Geological survey and mapping - When possible geochemical sampling and analysis (or review of existing data from nearby drilled wells) - Geophysics including either acoustic or magnetic methods The first scientific investigation steps are: GEOTHERMAL PLANTS RISK MITIGATION

19. GEOTHERMAL PLANTS DRILLING STATISTICS SUCCESS RATE OF GEOTHERMAL DRILLINGS The success rate of a geothermal drilling in areas with existing drilling data can reach up to 90%. With recent developments in the geology, hydrogeology, petrology and mapping success rates have reached 90% in particular in Iceland and New Zealand. The New Zealand based geothermal consulting company SKN stated in 2006, that in fields with extensive existing data and feedback from existing drillings the average hit rate during development has reached these 90%. The success ratio in Iceland has currently reached 85 to 90% thanks to companies like Enex, specialized on creating computerized geographical maps of the area to sit the drillings very accurate. Enex also developed the Neuried project.
20. GEOTHERMAL PLANTS DRILLING STATISTICS SUCCESS RATE OF GEOTHERMAL DRILLINGS In Germany the existing geological and geophysical data data are of very good quality and have been monitored for a long time by the regional and national geological and hydrological institutes. In the Rhine region, where Neuried is situated the drilling is done in a fractured zone, which can explain why acidification may be required to obtain the requested flow of 75 liters per second from the production well. This was stated by Prof. Dr STOBER, head of the Geological Department of Land Baden-Wurttemberg in a last assessment. For the project Neuried, we give here under a review of the drillings performed in Germany in the past years.
