A tracer test was carried out in a geothermal doublet system to study the injection behavior of a developed reservoir known to be fractured. The doublet produces about 20.2 l/s of 71 C (320 gpm of 160 F) water that is used for space heating and then injected; the wells are spaced 76 m (250 ft.) apart. Tracer breakthrough was observed in 2 hours and 45 minutes in the production well, indicating fracture flow. However, the tracer concentrations were low and indicated porous media flow; the tracers mixed with a reservoir volume much larger than a fracture. 8 references.
