| Abstract | Geographical Information System (GIS) was used as a decision-making tool to determine the spatial association between exploration evidence layers and environmental evidence layers in the Sabalan geothermal field in northwestern Iran for geothermal exploration well siting. The wellsites are located contributing exploration and environmental datasets. The exploration data set comprises geological, geochemical and geophysical evidences. The environmental dataset contains restrictive (limitative) data layers and Classifying layers are taken into account for well siting. The Boolean and Index Overlay models were developed for processing the site selection. The result of exploration data modeling was combined with the result of environmental suitability analysis for final well targeting. Three exploration well sites were suggested for exploration drilling. |
