Abstract [en]

Inclusion of shear-wave seismic studies in the characterization of reservoir analogues has a great potential to provide a more detailed understanding of changes in petrophysical properties and their direct impact on the seismic reflectivity. Presented in this study are mainly shear-wave shot records to illustrate the data quality and difficulties that can occur during acquisition, from two field sites in Denmark: (1) Stevns Klint, southeast Denmark,with numerous supplementary data and outcrops at a nearby cliff profiles and quarry walls. At Stevns Klint a 500 m long shear-wave data set was already acquired. (2) The Rørdal chalk quarry in Aalborg, northern Denmark, which offers the opportunity to sample plugs horizontally and vertically with a very close tie planned high-resolution seismic profiles. Stevns and Rørdal are characterized by different acquisition conditions. While measurements at Stevns were carried out on an asphalt road, Rørdal gives the opportunity to measure directly on the chalk surface. However, we show through examples how excavating machines in Rørdal can produce reflections similar to the ones produced by the source signal and, therefore, preclude data acquisition during ongoing quarrying.
