Tracer injection for identifying reservoir and transport parameters in geothermal sources has become an important procedure for designing an optimum reinjection program. Field tests have been analyzed using convection-diffusion equation to predict fracture size, width and probable thermal breakthrough times. The present study was conducted in a laboratory fractured reservoir model whose physical properties were known. The tracer, KI, breakthrough profiles were analyzed for different injection-production depth schemes. For different patterns different preferential flow paths existed which were then affected by flow through auxiliary paths. A correlation between heat and mass transport was used to define an apparent heat transfer coefficient for the flow. 3 tabs., 5 figs., 7 refs.
