Abstract
Saudi Arabia offers a strong potential for geothermal energy, but only a limited amount of exploration efforts has taken place. We conducted a preliminary, low-cost, reconnaissance level evaluation of the western volcanic areas (harrats) based on mapped geology and existing seismic data. The emphasis is on the Harrat Rahat volcanic area in western Saudi Arabia although a survey of other major harrats is conducted using geologic data. The goal is to test the procedure and identify areas for future, more intensive study.
