Abstract
Geophysical well logging at San Kamphaeng geothermal area began in 1981 for six shallow drill holes(500 m depth) and recently for a deep drill hole of 1,500 m depth (GTE-7). Geophysical well logs are composed of ES-logs (resistivity and self potential measurements), caliper and temperature logs. The ES-logs show high fracture permabilities throughout the GTE-7 well bore at many depth levels, but the temperature gradient of this drill hole is normal (33°C/km). The temperature gradients would be increased if fracture permeability were associated with a major fault zone. The heat source for this geothermal area ma be a deep seated body near the area of the GTE-6 and GTE-4 wells.
