| Abstract | A technique for separating shallow heat source effects from temperature gradient data is presented. The technique makes use of the depth dependant information available in the wave number spectrum of the gradient data. The effectiveness of the technique is demonstrated on a two dimensional numerical model of a geothermal system containing a deep geothermal reservoir which is masked by a warm, shallow aquifer and a thermal spring. This geothermal system is representative of those found throughout the Basin and Range province. The resulting filtered gradients produce an excellent prediction of the temperatures in the modeled geothermal reservoir. |
