Geothermal Resources: Unearthing Potential

Clean and sustainable - An endless source of environmentally friendly energy is the heat from the Earth itself. Discover, assess and utilise this resource with our individual services or complete solution packages. Whatever your project phase, we have the know-how.

With growing demand for climate-friendly sources of renewable energy, we can no longer ignore what has been right under our feet all along!

Various techniques for drawing heat energy from deep within the Earth are currently being tested in Germany and other countries around the world. These include deep geothermal probes, the use of deep groundwater aquifers and HDR (Hot Dry Rock). The potential of old mine workings and mine water is also being tested for geothermal utilization.

DMT: Your partner for geothermal energy

For over 15 years DMT has been involved in an advisory capacity for numerous geothermal projects that use varying techniques and by supplying professional geophysical instrumentation. In connection with geothermal energy we offer a range of single services, combined services as well as complete solution packages to support you in finding the right site, reducing drilling risks, increasing safety, minimising costs and improving productivity.

In both the national and international geothermal energy sectors we focus on what’s paramount – Exploration. Typically DMT’s services in this field include the planning, carrying out and subsequent analysis of 2D and 3D seismic surveys, underground modelling, simulation and drilling path planning. We have highly qualified professionals and the best possible Equipment to supply you with the valuable information you need to make your geothermal project a success.

Additionally we perform microseismic event monitoring, environmental impact and surface impact assessments and provide the purpose-built online condition monitoring system PlantSafe for monitoring your pumps.

No matter what phase your geothermal project is in, our specialists are on hand to advise you. Just get in touch!


DMT is a member of the world's second largest geothermal association, Bundesverband Geothermie e.V., through which we are integrated into national and international networks such as the International Geothermal Association (IGA), the European Geothermal Energy Council (EGEC) and the Bundesverband Erneuerbare Energien (BEE).

Furthermore, we are represented in the Geothermal Energy Expert Committee of GDBM, whose aim is to promote further development of this form of energy. The regular committee meetings are attended by project developers and operators, universities, engineering companies, suppliers and authorities. The focus is on the use of warm water from former mines as well as on deep geothermal energy, i.e. the collection of ground heat by means of borehole mining.

Since 2017 DMT has also been a partner in Greentech.Ruhr, a network of innovative companies, research and educational institutions and various public institutions in the environmental sector. The Greentech.Ruhr project is an initiative of Business Metropole Ruhr GmbH, whose aim is to promote the Ruhr Metropolis worldwide as the leading area for the development and provision of environmental services and solutions.

DMT is committed to finding clean, sustainable solutions for the future!


DMT is partner in the EU INTERREG programme DGE-Rollout (Deep Geothermal Energy Rollout) in North-West Europe.

The DGE-ROLLOUT Project target is to facilitate the uptake of low carbon technologies, products, processes and services in sectors with high energy saving potential, to reduce GHG emissions in NWE.

Within this Project, DMT provides exploration and engineering support for deep geothermal energy usage, is the first information source for stakeholders & investors and ensures transparency of geothermal energy usage to the public.

DMT activities are:

  • Underground Heatflow simulation: DMT provides underground heat flow models to reduce drilling risk, to plan drill paths and to optimize parameters of hot water processing plants.
  • Geological Atlas of the Ruhr Area: DMT supports the Geological Service of North-Rhine Westphalia to produce a Geological Atlas, to reduce the drilling risk in the Ruhr Area. Exploration data from coal mining will be made accessible and usable.
  • Seismological Data Center in the Bergbau-Museum Bochum: DMT, together with GZB, will set-up a seismic monitoring network to provide automatic real-time observation of seismological data. It will provide real-time location and event assessment and make induced seismicity transparent to the public.
  • Exploration Support: DMT advises stakeholders concerning underground exploration of geothermal resources.

The European Union promotes "European territorial cooperation" through its structural and investment policies. Its INTERREG programme provides a framework to develop innovative project ideas and to deliver concrete new results. It  supports transnational cooperation between national, regional and local partners. North-West Europe is one of the six programme areas.

Your Energy - Our Performance!

Investing in competence and quality at an early stage for long-term efficiency and sustainable success.














With decades of experience in the exploration of all kinds of natural resources, our main focus in the national and international geothermal sector is also on this project stage. We help to locate and evaluate geothermal deposits. Corresponding services are typically the planning and execution of 2D/3D seismic measurements, their evaluation, underground modelling, as well as simulation and drilling path planning.

Furthermore, microseismic event monitoring, the monitoring and evaluation of environmental impacts and effects to the earth's surface, as well as the online condition monitoring of your systems using our own product PlantSafe is a key area of our expertise.

In addition, further services such as fire protection, plant safety, power plant construction, certification, etc. can be offered either by DMT or our sister companies within the TÜV NORD GROUP.

  • Exploration
  • Resource Evaluation
  • Site Investigtion
  • Monitoring
  • Plant Engineering
  • Plant Safety
  • Certification

QHSE Management – Safeguarding your Project

Within DMT's QHSE management system, a committed leadership and clear distribution of roles and responsilities are supplemented by thorough evaluation and risk management. The result is a minimized risk of accidents and work-related illnesses. Furthermore, our teams are highly professional and operate in an environmentally responsible manner, thus minimizing environmental pollution and damage.

Our QHSE management system is based on the highest international standards:

  • ISO 9001 - Quality Management
  • ISO 14001 - Environmental Management
  • OHSAS 18001 - Occupational Health and Safety Management

Plus we follow guidelines form industry-specific bodies such as:

  • OGP - International Association of Oil & Gas Producers, London, UK and Houston, USA
  • IAGC - International Association of Geophysical Contractors, Houston, USA


In the past 10 years DMT has served some 60 geothermal clients from across Western Europe and even Japan. Many of our projects were carried out on behalf of municipal utilities companies, for example Stadtwerke München and Stadtwerke Schwerin. We have assisted a number of major energy firms such as RWE, E.ON and OMV with their exploration activities, but also provided advice and services to small-scale enterprises. We pride ourselves on the long-term business relationships we have developed with many of our clients. 

We value the close cooperation with our long-term clients and business partners

"We have been working with DMT in the field of geothermal exploration for almost 10 years. We appreciate not only their unquestionable professional competence, but also their often pragmatic and unbureaucratic support with interdisciplinary topics as well as their flexibility with time-critical requirements." - Dr. Robert Straubinger, Managing Director, Enex Power Germany GmbH

"Collaboration with DMT has become established in numerous areas and has proven itself many times over, as our competencies, especially in the field of deep geothermal energy, complement each other very well. DMT is a reliable partner for whom the solution for the end customer is paramount." - Dr. R. Kahnt, Member of the Executive Board and Head of Department, G.E.O.S. Ingenieurgesellschaft mbH
