Fig. 14From: Hydrochemical aspects of high-temperature aquifer storage in carbonaceous aquifers: evaluation of a field studyTemperatures corrected with the cold reservoir influx by means of the development of the sodium ion concentrations during production stage 0 (\({T}_\text{Inj}=65\,^{\circ }\text {C}\)). The colored bars at the top symbolize injection (red), calibration of the probe (green) and production (blue) stageBack to article page
