The tender concerns the processing of the 3D seismic data, the evaluation of the VSP measurements in 4 existing boreholes and the structural and stratigraphic interpretation of the processed data including the VSP measurement results and other drilling information.

The 3D seismic data and the VSP data of the seismic measurements in the area of the Asse II mine must be processed and interpreted according to the current state of the art. The results of separate close-line measurements and time measurements of the explosive seismic excitations are to be included in the processing. The 3D measuring surface to be processed is expected to be approx. 36.5 km 2 ,

The processing should be optimized for a depth range between approx. 200 m to approx. 2,000 m (Zechstein base), with a special focus on the high-resolution, correct position mapping of the salt / overburden interface in the central area of the steep south flank of the Asse salt structure , When processing data, if possible, the southern flank of the Asse salt structure should be processed first.

The contractor should provide the following services in the context of this tender:

- processing of 3D seismic data,

- Evaluation of VSP measurements in 4 existing holes and

- Structural and stratigraphic interpretation of the processed data, including the VSP measurement results and other drilling information.
