From October 7 till 21, 2013 control measurements were carried out in three approximately 800 m deep wells at the Ketzin pilot site (Ktzi 200, 201, 203). These included among others the inspection of the well casing with the help of a video camera and measurements to characterize the cement behind the casing. Furthermore, water and gas samples were taken for geochemical and microbiological analyses.
With these measurements scientists can check the status of each well.
Moreover, logging activities complemented the work at the now partly closed observation well Ktzi 202.
