Start of geothermal measurements in November

With the “Pfälzer Wärme powered by SWK” project, we are investigating the geothermal potential beneath Kaiserslautern. Seismic measurements are due to start in November. Following the detailed information provided at the Energy Forum, the Vibro-Truck was available in July and October to be touched and put into action – vibration included.

Looking underground via vibration

3D seismics is a technique that works in a similar way to an ultrasound examination. Sound waves are sent into the subsurface. The result is a detailed image of the geological structures and flow paths in the earth’s layers.

The exploration area covers more than 150 km² 

The convoys drive along the planned measuring lines in the 150 km² measuring area. The 12-, 24- and 26-ton Vibrio trucks stop at measuring points every 30 meters. We generate controlled vibrations (sound waves) with the help of lowerable floor plates.  

The sound waves are reflected at the boundaries of rock layers. This echo is recorded by measuring devices, known as geophones, distributed across the surface. This allows us to create a precise 3D model of the earth’s layers. The measurements take a total of six to eight weeks, depending on the weather.  

Around 28,000 geophones in use

We lay out the geophones, cubes with an edge length of approx. 15 cm, over a large area – along roads and paths, in meadows, fields and properties. They are localized via GPS. The measuring devices with the data stored in them are very valuable for the success of the measurement. It is therefore important that the geophones remain in place. They are collected again by DMT after the measurements.  

Temporary noise and traffic obstructions  

The convoy of vibro-trucks moves very slowly – comparable to a moving construction site. This can lead to obstructions, even if the planning avoids peak times such as rush hour.  

During the measurements, we briefly generate a lot of noise. According to project manager Dr. Uwe Baaske from SWK, you can roughly compare the noise level with the passage of a refuse collection vehicle. Vibrations will be noticeable in the immediate vicinity. We will inform all residents in the measurement area in advance.

Thank you for your support

 The Pfälzer Wärme team monitors that there are no critical vibrations in buildings. If you have any questions or comments about the measurements, please contact the team at pfaelzer-waerme@swk-kl.de.

Residents can also contact this office if they suspect that the measurements have caused damage. The experts from Pfälzer Wärme will then carefully investigate the matter.

We ask for your understanding and patience for the temporary restrictions and noise. Thank you very much! Together, we are making an important contribution to the reliable supply of sustainable and environmentally friendly energy in our region.
