Laboratory studies have been performed at testing stability of perfluorinated cyclic hydrocarbon (PFC) gas tracers at supercritical conditions. Both static and dynamic tests have been performed at a specially constructed equipment which can tolerate such hard conditions (>374 °C, >218 bar). Static stability results indicate no rapid thermal degradation of the tested tracer candidates within the time frame of the performed stability test (2 months). However, the dynamic flooding experiments using crushed rock from the Krafla IDDP-1 field on Iceland indicate interactions between the rock material and the tracer candidates. This is an interesting result because PFC tracers have been detected in earlier studies in the Krafla field.
