To answer this question, it is necessary to evaluate the resolving capability of seismic methods at target depths. Therefore a case study in the northeastern part of Germany was carried out to obtain information for an optimal configuration of such a seismic experiment.The study area is located near Gross Schoenebeck, approximately 40 km north of Berlin. 630 vibrator sweeps at the same location were recorded by a fixed geophone spread. Different frequencies and sweep lengths were used to investigate stability of amplitude and waveform information in the seismic traces. The analysis provides an estimate of the possibilities and limitations of seismic time-lapse experiments for monitoring property changes in deep reservoirs. The geometry was designed to focus on the stability of a strong reflector (Permian/Triassic boundary) in 2.4 km depth, overlain by a partly unconsolidated sedimentary cover. We present results of the estimation of factors, such as source and receiver stability and influence of seismic noise, which will have an impact on future experiments.
