“…This leads to the K2 at 463 ms, the top of the reservoir at 506 ms (offset to K2 43 ms) and the bottom of the reservoir at 512 ms (offset to K2 49 ms). This is in accordance with the top of the Stuttgart Formation in Lüth et al (2011), which was picked 42 ms below the K2 horizon (Figure 1.2). Fig.…”

“…According to Lüth et al (2011), a time-lapse signature could be identified in the data by a more sensitive estimate of the change in seismic response than the travel times. This method consists of "a multiplication of the cross-correlation of corresponding baseline and repeat records with the logarithm of their amplitude ratios, in a 20 ms window after the picked P-wave times" ).…”

The source points of the offset VSP are located at the far end and in the middle of each of these seven lines.…”

“…At the onshore Ketzin site, we found that refraction static corrections followed by residual static corrections gave poor results on repeated 2D and 3D seismic surveys Lüth et al, 2011;Ivanova et al, 2012). The main reason for this is the general inability of refraction static corrections to provide sufficiently accurate velocity models of the weathered layer, which is due to three factors.…”

A method for static correction of time-lapse differences in reflection arrival times of time-lapse prestack seismic data is presented. These arrival-time differences are typically caused by changes in the near-surface velocities between the acquisitions and had a detrimental impact on time-lapse seismic imaging. Trace-to-trace time shifts of the data sets from different vintages are determined by crosscorrelations. The time shifts are decomposed in a surface-consistent manner, which yields static corrections that tie the repeat data to the baseline data. Hence, this approach implies that new refraction static corrections for the repeat data sets are unnecessary. The approach is demonstrated on a 4D seismic data set from the Ketzin CO 2 pilot storage site, Germany, and is compared with the result of an initial processing that was based on separate refraction static corrections. It is shown that the time-lapse difference static correction approach reduces 4D noise more effectively than separate refraction static corrections and is significantly less labor intensive.

Since 2004, research at the Ketzin pilot site in Germany contributes to the understanding of the geological storage of carbon dioxide (CO 2 ). For the Ketzin project public outreach has been a key element from the very beginning. Involvement of the local public, scientists, stakeholders and competent authorities allowed for the consideration of their different interests. The dissemination of up-to-date and factual information along the entire chain of activities is a central component of the project. The work presented here summarizes the activities and the experiences of the public outreach accompanying the research on CO 2 storage at the Ketzin pilot site.
