Project: Quicklook Processing (QLP)
In the context of "Sachplan Geologische Tiefenlager" ("Sectoral Plan Deep Geological Repositories") Nagra
investigated three siting regions in northern Switzerland. As part of the investigations, Nagra carried
out three 3D seismic surveys between 2015 and 2017. The aim of this project was to provide a near-term
primal interpretation for exploration purposes, providing the foundation for further special
interpretation, such as tectonics and sedimentology.

Projekt: Depth Interpretation
Based on the prior carried out QLP, the interpretation was conducted by using the software Petrel.
Initially, the seismic marker horizons were mapped manually, which primariliy included the interpretation
of bigger faults. In the last step, the grid was finalized by using automatic search algorithms.

Projekt: Processing-accompanying Interpretation
In the course of 3D seismic data depth-processing, an interpretation of selected reflectors was conducted,
which was performed resulting in a consistent inline- and crossline grid - followed by gridding the
interpretation results and inversion into an interpretation. Thus, a depth value was received for every
CDP in the seismic.
