Abstract
A method of predicting thermal breakthrough from tracer test analysis is presented. Because the ratio of fluid velocity to thermal velocity is a constant, any variations in fluid flow are identically reflected in the thermal front, even in heterogeneous media. A variable transformation is presented which facilitates comparison between tracer effluent concentrations and temperature histories. An example demonstrates the success of the method in predicting the onset of thermal decline in a heterogeneous porous media.
