| Abstract | Thirty-nine potential geothermal tracers have been tested for thermal stability at temperatures up to 250°C. The tracers were aromatic hydrocarbons with moieties of trifluoromethyls, sulfonates, methyls, fluorides, or carboxyls. Significant decay of these tracers, except for the perfluorinated compounds, was noted only between 200°C and 250°C. At 200°C, 32 of the 39 tracers survived for one week; at 250°C, 15 survived. The perfluorinated tracers decayed completely at all temperatures tested. These results show that certain derivatized hydrocarbons are potentially suitable as geothermal tracers. Future research will include testing these tracers in the presence of solid, liquid and gas phases that are common in geothermal reservoirs. |
