Abstract
It is well known that full spatial information about the underground geology generally can be retrieved by 3D seismic investigations. The advantage of recording multidirectional data information allows imaging of complex underground features, such as fault systems, sinkholes or dome structures.
The downside of a 3D seismic investigation is the operational requirement of laterally free access to the investigation site at the surface to lay out the seismic recording equipment and deploy the seismic source. This is typically no problem, for example, for large scale operations in desert-like areas for the oil and gas industries. In urban areas, though, access is limited due to building structures or transport infrastructure. Moreover, other constraints such like the public interests require significant considerations during all stages of a seismic operation.
This work summarizes the possibilities and limitations of carrying out a detailed 3D seismic reflection investigation in urban environment by presenting a case study investigation program which has been carried out across a small community in Germany.
