| Abstract |
Recent studies on the Uganda geothermal systems have focused on three geothermal prospects, Katwe, Buranga and Kibiro, all located in the tectonically active and Recent volcanic belt in the Western Rift valley along the border of Uganda and the Democratic Republic of Congo. Geothermal systems and saline and fresh water lakes characterize the Rift Valley. The three areas were chosen for study because of their volcanic and tectonicfeatures that indicate a powerful heat source and high permeability. The objective is to develop geothermal energy as an alternative energy source to hydro and others to meet the energy demand of rural areas in sound environment. The geology and geochemistry results for the surface hot springs indicate that potential geothermal systems exist at depth. The subsurface temperatures of 160-200 ?C, 200 ?C, and above 200 ?C for theKatwe, Buranga and Kibiro prospects, respectively, have been inferred bygeothermometry and mixing models. These temperatures are suitable for electric power production and direct use in industry and agriculture. Other areas outside the tectonically active and recent volcanic belt have typical fluid temperatures suitable for direct application to domestic use, agriculture and industrial heating. Surface exploration studies have reached advanced stages in the three areas with the execution of the ongoinggeophysical survey, the results of which will be used to upgrade the current geothermal model of geology and geochemistry and develop an integrated model that will be a basis forsiting the exploration wells. |
