The reports were written over a long period of time. Hence organisation, layout and the degree of documentation vary from report to report. Most reports, however, contain the elements listed below.

- Main volume

• Introduction

• Summary and conclusions

• Core-wise description and discussion of results, with the following sections:
  - Summary
  - Seismic interpretation (correlation)
  - Sedimentology
  - Biostratigraphy
  - Organic geochemistry

• Seismic interpretation (whole area, including descriptions of the structural framework and the seismic units and subcrop maps)

• Discussion (stratigraphy and regional correlations, interpretation of provenance, burial depth - uplift - erosion, tectonostratigraphic evolution)

• The main volume typically also contains summary sheets of each core (1:500 or 1:1000), a geological map with sections, interpreted seismic sections.

- Appendix volume(s)

• Field work (drilling operation, navigation)

• Analytical methods

• Consultant reports (e.g. ichnofabric, apatite fission track, geomechanics, thermal conductivity)

• Discussion of selected subjects (e.g. of petrophysical core measurements and wireline logs)

• Biostratigraphical range charts

• Sedimentological core logs (1:100) with interpreted depositional environments

• Organic geochemical data (Tables with results from headspace and occluded gas analysis, TOC/Rock-Eval pyrolysis, pyrolysis-GC, vitrinite reflectance analysis, visual kerogen analysis, extraction/group separation, saturated hydrocarbon GC (gas chromatography), biomarker analysis (SAT GCMS, ARO GCMS). Figures showing gas chromatograms and mass fragmentograms. Description of analytical methods. Summary sheet showing organic richness and Rock-Eval kerogen type for the cored sections.)

The Vøring Basin (1993) report includes a separate volume on experiences from deep-water drilling.

 

Available digital data

General note

Most of the projects were carried out during the "paper era" when digital storage space was very expensive and the printed report was considered to be the end product. In the early projects, wireline logs were reproduced on paper and the digital files were not kept. Seismic data were mostly analogue. Word processing was done on systems that ceased to exist, and files were neither taken care of in a structured fashion nor transferred to PC systems. Therefore, and because methods developed during time, not all types of data are available from all projects and coreholes.

Reports

A considerable part of the tabulated data has, however, been retyped and is available as spreadsheet files (Excel). This includes:

• Sonic velocity determined on the freshly drilled core

• Spectral gamma ray analysis of core sections

• Organic geochemical data (but not chromatograms or mass fragmentograms)

• XRD results

• Porosity and permeability data (plug measurements, mini-permeameter, porosity estimated from thin sections by modal analysis)

• Thermal conductivity data

• Selected rock mechanical data.

Some of the reports have been scanned and can be made available in PDF format. Note that these are pictures and that the text is not searchable.

Core photos

• Low-resolution pictures of all cores are published at this website.

• JPG files (300-400 dpi) in high and low quality are available for all cores. They are automatically delivered together with the report, but can also be ordered independently.

Wireline log data
Slimhole logging data (ASCII, LAS) are available for most holes drilled since 1988. Short holes were not logged, and holes drilled in unstable formations were, if logged at all, only logged inside the drill string.

Seismic data

High-resolution digitally acquired seismic data (2D) are available on paper or film. SEG-Y files (original or re-acquired from scans) are now also available for most surveys. High-resolution analogue data are only available on film or paper. Part of the digital seismic data can be made available through the DISKOS storage system.
