Geothermal Well Site Suitability Selection Using Geographic Information Systems (GIS) and Remote Sensing: A Case Study of the Eburru Geothermal Complex

Abstract

Conventional geothermal site selection process comprises a multi-disciplinary field approach that involves the integration of several surface exploration methods such as geological, geochemical, geophysical and environmental baseline surveys. Geographic Information Systems (GIS) multi-criteria analysis and remote sensing image analysis are emerging technologies used in the establishment of favorable areas for geothermal well siting and targeting. They are convenient relatively cost-effective methods useful in feasibility and actual field stages of geothermal resource exploration. The study seeks to establish favorable areas for geothermal well sites within the Eburru high-temperature geothermal field using the aforesaid approaches. The index overlay analysis function using logic and math operators in Model Builder will be used in the suitability selection process. The expected output is a suitability map envisaging where the geothermal wells can be optimally located within the social-ecological-technical conflict landscape.
