Abstract
At the Ketzin pilot site for CO2 storage, 67 kt of CO2 were injected between 2008 and 2013 in to a saline aquifer. In October 2014, part of the formerly injected CO2 was retrieved from the reservoir. 240 t of CO2 and 55 m3 of brine were back-produced and an interdisciplinary monitoring accompanied the field experiment. It indicates that a safe CO2 back-production is feasible and can be performed at both, stable reservoir and wellbore conditions.
