M l N l S T R Y OF E N V I R O N M E N T AND ENERGY

The Geological Survey of Dennark and Greenland (Danmarks og Gmnlancls Geobgi.de Undersagelse - GEUS) is a research and advisory institution in the Danish Ministry of Environment and Energy.

GEUS was established in 1995 as a merger befaxen the fonner Geological Survey of Denmark (Danmarks Geologiske Undersageelse - DGU, established in 1888) and the former Geological Survey of Greenland (Granlands Geobgiske Undersagelse - GGU, established in 1946).

'The Survey's primary finction is to provide the essential geological semioe for the utilisation and protection of Dennark's, Greenland's and the Faeroe Island's natural resources. This involves mapping, data collection and basic research, in addition to providing impartial advice and presenting geological results to both the general public and the scientifi community.

The Survey has both a research and an advisory role with respect to environmental protection, water supply, raw n a W , exploration for and exploitation of oil, natural gas, geothermal energy, nature conservation, environmental history and climate.

In addition, the Survey takes part in research programmes supported by nafional and i n t e d d fino% and undertakes contract assignments fir private firms, concerning environment, raw materials and energy.

The following scientific publication series are issued by GEUS.

Preface

This twenty-fourth volume of the "Well Data Summary sheets" together with volumes twenty-three, twenty-five and twenty-six which have been prepared concurrently, includes data from wells in the Danish North Sea.

With the exception of the Alma-lx well in volume 26 and the Gert-4 well in volume 23, all the included wells have been released and can be found in the previous volumes (1-16).

The primary purpose of producing these four volumes (23-26) has been to update the previously released wells and produce them in our new format. With the new volumes 23, 24, and 26 together with well data from volumes 17, 18, and 19, all released wells from the Danish Central Graben are updated in our new format. Volume 25 includes Danish North Sea wells from outside the Central Graben area.

The Ibenholt-1 well and the Felicia-l/lA well included in the regional volume 25 were previously included in volumes 21 and 20 respectively.

2. Edition Minor corrections have been made since the first edition. The "Complete index of released wells" has been updated. References are made to well data from volume 27 currently at the printers.

Volume 27, 28 and 29 are regional volumes; volume 27 includes well data from South- ern Jylland; volumes 28 and 29 cover well data from Northern Jylland. All data from released Danish North Sea wells are included in volumes 17-26 and 30.

Data references are made to the revised volumes and not to the original published reference.
