Table 2 Data and material of the E GrSk 3/90 and Gt GrSk 4/05 boreholes

From: From pilot knowledge via integrated reservoir characterization to utilization perspectives of deep geothermal reservoirs: the 3D model of Groß Schönebeck (North German Basin)

a) Core data (E GrSk 3/90 only; coring in Gt GrSk 4/05 was planned but could not be realized). The E GrSk 3/90 borehole was cored in the depth range of ca. 4040–4270 m (230 m). Due to disposal of core material in the late 1990s, only the lowermost 63 m of this section are still available in the repository

  Density and porosity

In total 344 measured samples: 287 legacy samples (Hamann et al. 1991), 29 samples (Trautwein 2005), 17 samples (Lotz 2004), 11 samples (this study)

  Gas permeability

In total 137 measured samples: 109 legacy samples (Hamann et al. 1991), 28 samples (Trautwein 2005) plus 3 measured under in-situ conditions (Trautwein 2005)
