DMT, a company of the T\u00dcV NORD GROUP, is starting a 3D seismic survey on behalf of Stadtwerke M\u00fcnchen to investigate the deep subsurface. As part of the GIGA-M project, DMT is carrying out seismic surveys across an area of around 1,100 square kilometres. The data collected will provide a three-dimensional image of the subsurface, thereby forming the geological basis for the further development of deep geothermal energy in Munich and the surrounding local authorities.<\/p>\n
The thermal water reservoir in the Greater Munich area is already being utilised via around 50 boreholes with a total thermal output of approximately 400 MW. The additional potential that can be tapped is estimated at more than 1,000 MW and is now being precisely determined through the largest-ever seismic site survey in a highly populated urban area.<\/p>\n
The new data can be used to identify potentially suitable sites for future geothermal projects, to further develop existing plants, and to coordinate the use of geothermal energy in the study area in the long term.<\/p>\n
The GIGA-M project, funded by the Federal Ministry for Economic Affairs and Energy (BMWE), is a joint initiative involving the Technical University of Munich (co-ordinator), Stadtwerke M\u00fcnchen (head of the seismology team), Energie-Wende-Garching (seismology partner), the Ebersberg-Munich Energy Agency, the District of Munich and the City of Munich.<\/p>\n
Modern seismic technology provides insight into the subsurface Specialised measurement vehicles known as \u2018Vibro-Trucks\u2019 are used for the measurements; these transmit controlled vibrations into the ground. The signals reflected off the various rock layers are recorded by thousands of geophones \u2013 highly sensitive ground sensors \u2013 and then analysed. The measurement data is used to create a high-resolution three-dimensional model of the subsurface, which provides information on geological structures and areas potentially suitable for deep geothermal energy.<\/p>\n Through the GIGA-M project in Munich, DMT is further expanding its role as one of the leading partners in the development of geothermal projects and the exploration of raw materials.<\/p>\n \u201cA 3D seismic survey of this scale poses unique challenges in terms of planning and execution. In the densely populated survey area, a large number of measurement points, the deployment of vibro-trucks and the recording by thousands of geophones must be precisely co-ordinated. It is essential to generate a consistent data set across the entire survey area, from which the 3D model of the subsurface is subsequently created,\u201d says Dr Christian Henke, Head of Seismic Exploration & Processing at DMT.<\/p>\n DMT has already carried out a large-scale 3D seismic survey in M\u00fcnster to investigate the deep subsurface with a view to geothermal energy utilisation. The experience gained from planning and carrying out seismic surveys in urban areas is also being applied to the campaign in the Greater Munich area. Furthermore, DMT has many years\u2019 experience in geophysical exploration and subsurface investigation for raw materials and energy projects worldwide.<\/p>\n","protected":false},"excerpt":{"rendered":" DMT, a company of the T\u00dcV NORD GROUP, is starting a 3D seismic survey on behalf of Stadtwerke M\u00fcnchen to investigate the deep subsurface.

\n<\/strong>\u201cWith GIGA-M, we are setting a new benchmark for seismic site exploration in urban areas. Large-scale 3D seismic surveys provide the data required to assess and systematically develop geothermal potential in the Greater Munich area. The experience gained can also provide important impetus for other cities and regions that want to develop deep geothermal energy as a component of their heat supply,\u201d says Dr Maik Tiedemann, CEO of DMT GmbH & Co. KG and CEO of the T\u00dcV NORD GROUP\u2019s business unit Energy & Resources.<\/p>\n
