GEUS The National Survey
In 1995 the Geological Survey of Denmark (1888)
was merged with the Geological Survey of
Greenland (1946) into GEUS. GEUS is today
responsible of all geological matters within the
Kingdom of Denmark, including Greenland and the
Faeroe Islands... .. and carries out geological
related basic and advanced research of relevance
to the society, both in form of advisory and
consulting activities. GEUS is a consultancy
institution for Danish and Greenland authorities
in questions concerning important geological
conditions..

The National Survey
GEUS is a national research and advisory
institute under the Danish Ministry for the
Environment providing RD and advisory services
for government agencies, local authorities and
private enterprises in Denmark as well as
internationally Staff 280 persons. - Annual

GEUS National Databank

• The Act concerning the use of the Danish
  subsurface states that all data acquired during
  activities in the Danish subsurface must be
  forwarded to the Geological Survey of Denmark and
  Greenland (GEUS).

This makes GEUS the national databank for all
types of data from the Danish subsurface.

• All released data are available from GEUS.

9
National Data Archives
The National data archives .. is responsible for
building and maintaining the records of past
activities. These data bank activities comprise
very extensive printed and electronic files
covering nearly all aspects of the subsoil. A
separate warehouse facility houses hundreds of
kilometers of cores samples and many thousand
representative sediment and rock samples. GIS
technologies are extensively applied

GEUS Geothermal Activities
GEUS has since the 80ties played an important
and an increasing role within exploration of
geothermal resources in the Danish subsurface and
has since 1998 assessed the possibility of
expanding geothermal energy in Denmark. The
subterranean structure of Denmark contains
geological structures which contain hot water.
The subsurface temperatures in Denmark to does
not allow direct production of electricity.
However, hot water can be utilised for district
heating production, either directly or via
absorption heat pumps or electric heat pumps.
The first plant in Denmark was established in
connection with the district heating supply in
Thisted in 1984.
13
Geothermal Activities
GEUS has for many years provided advisory,
research and consultancy services within the
field of geothermal activities. GEUS has
particularly been involved in areas as structural
development, compilation and formulation of
geological models in an attempt to predict where
to find reservoirs suitable for geothermal
exploration. This ongoing work has further
contributed to the geological knowledge of
production characteristics and the stability of
the hot water recovery, i.e. risking.

Geothermal Energy today

• The first national study on geothermal resources
  was initialised in 1981.
• Geothermal resources is mainly related to the
  Mesozoic succession of the
• Danish Basin and Fennoscandian Border Zone.
• This succession has been the target for
  exploration activities since 1935 and
• is known from approx. 60 deep wells drilled
  for hydrocarbons, geothermal
• energy or gas storage.
• Denmark has one geothermal plant, located in
  Thisted in the north-western
• part of Denmark. It produces heat from 44C,
  15 saline geothermal water
• pumped from the Upper Triassic Gassum
  sandstone aqiuifer at 1,2 km.
• Experience from the Thisted plant have shown
  that heat and power plants
• integrated with geothermal plants with heat
  pumps (primary absorption heat
• pumps) can be used to produce heat and power
  with a high efficiency.
• Thus, although Denmark has moderate temperature
  gradients (0.03C per
• meter), many areas and stratigraphic levels
  hold warm sandstone aquifers,
• which can be used for district heating.

New Geothermal Projects
In 2000, a confidential study of the geothermal
potential in the Copenhagen-Malmö region was
initiated on behalf of DONG A/S. The geothermal
study was successfully completed when 70 degrees
hot water was found in a sandstone layer more
than 2600 metre under Copenhagen in the MAH-1
well. Prior to the successful drilling, GEUS had
carried out assessments of six possible
geothermal drilling sites and prepared the
geological foundation for the drilling, using
DONG A/S as the operator. The ongoing research
provides the knowledge base for the advisory
capability, and GEUS is frequently called upon to
supply geological, geophysical and engineering
opinions on licence bids, drilling plans and
field development plans put forward by companies
operating on Danish territory.
17
New Geothermal Projects
Geologists and geophysics from GEUS participated
in the work both during and after the drilling of
this new geothermal well and GEUS has since been
2000 been working on improving our knowledge
about the geothermal potential in
Copenhagen-Mølmö area. Based on the positive
results a new demonstration plant is expected to
be established in the spring 2006 and is expected
to generate the heat needed by 4000 households or
1 of the total heat demand in Copenhagen. Furthe
rmore, as a direct result of these efforts,
geothermal exploration has now been resumed in
the rest of the onshore Danish area, and a number
of prospective areas will hopefully in the near
future be identified and further assessed by the
GEUS.

GEUS and ENGINE
At the moment Denmark has operating experience of
geothermal energy based only on one small
operating geothermal plant at Thisted GEUS hope,
- based on the positive results from the new
geothermal well near Copenhagen and the expected
following demonstration plant -, that the
interest for implementation and utilisation of
geothermal energy in Denmark with increase. This
has already resulted in renewed geothermal
interest and exploration in the other areas of
Denmark. Through ENGINE GEUS hope to learn, -
from other more experienced partners, - how we
further promote and use geothermal energy in
Denmark.
