To characterize the fluid residence times in the reservoir, an artificial marking of the thermal water circuit was started at the UnLimited test site in Bruchsal at the end of February 2022.
For this purpose, a defined amount of a conservative tracer was injected at the reinjection well. The dimensioning and evaluation of the artificial fluid tracer is carried out by the Unlimited research team of the University of Göttingen.
So far, no tracer signal is detectable in the investigated fluid samples. More information on the tracer testing will be published shortly in a separate format.
