| Abstract | The first two geothermal exploration wells in Thailand have been drilled in the vioinity of San Kampaeng Geothermal System. Available scientific data reveal that, the five promising geothermal systems in Thai 1and, San Kampaeng Geothermal System warrants the highest potential for power generation. Both exploration wells are 500 in depth. The first well (GTE-1) penetrated entirely into the Permo-Triassic volcanic rocks of basaltic and andesitic nature. Temperature gradients are steady both in the shallow agd deep portions of the hole with the value of 120 The second well (GTE-2) penetrated sedimentary successions of interbedded Palaeozoic shale, sandstone and limestones. Temperature gradients in the first 250 is approximately 500 m, the tempera gradi ents decrease to approximately 40-50 Several shallow drill holes were also drilled in the surface manifestations areas of the hot springs. with depth less than 30 m, geysering, discharge hot waters with temperatures above boiling point. The third exploration well, with target depth of 500 m, is presently being drilled. |
