Wagenborg Foxdrill team contributes to innovative geothermal project
In Graben-Neudorf, Germany, near Karlsruhe, Deutsche ErdWärme is busy with the realization of its first geothermal project. Two wells will be drilled to a depth of around 3 700 metres to extract thermal water that will be used to generate electricity and heat for around 10 000 households.
Innovative first
The project in the Upper Rhine region is a first using the latest drilling and extraction techniques. The Wagenborg Foxdrill team was involved in several phases of this special project.
Protecting groundwater
Wagenborg Foxdrill's conductor specialists were involved early on in this innovative geothermal project by both the project's main contractors, Huisman Geo and Ed. Züblin AG. One of the challenges for the team was to create two safe boreholes, each 36 metres deep in the upper earth layer. This was to shield the groundwater from the drilling activities.
Conductor piling solution
A conductor piling solution proved to be the safest, cleanest and most efficient solution. The Wagenborg Foxdrill team provided the complete scope for the conductor installation, including:
- Engineering and preparation
- Delivery of the 36'' conductors
- Deployment of hydrohammer type S-90
- Deployment of Foxdrill installation frame
- Installation of the two conductors
