GEUS STENLILLE 2022 –
The aim of this data acquisition


As part of the global effort to reduce CO2 atmospheric levels, the interest towards geological Carbon Capture and Storage (CCS) has increased significantly. Seismic investigations are important to identify areas where the geological conditions are suitable for safe and
sustainable storage.

This data package presents an innovative example of land seismic acquisition performed in Denmark to image the sedimentary stratigraphy in a candidate area for CO2 storage.

To achieve great investigation depths and at the same time guarantee dense spatial coverage at shallow depths, the data were recorded with a combination of geophones placed in a fixed geometry (10 m intervals) along the roadside and by a set of more closely spaced MEMS-based recorders mounted (2 m intervals) on a moving landstreamer.

Compared to the wireless data, the landstreamer scheme provided data of sufficient quality and with the additional advantage of high resolution at shallow depths.

Complementary use of both data reflection seismic imaging techniques provides information on the subsurface in a wide depth range, making such a survey highly promising for this purpose. Key reservoirs as well as the base of deep salt structures are imaged showing the potential of the survey. Potential faults and fracture systems have also  been noted requiring further investigations.
