Herrenknecht strengthens its Deep Drilling Business


Herrenknecht AG has acquired a majority stake in H. Anger's Söhne Bohr- und Brunnenbaugesellschaft mbH with retroactive effect from January 1, 2023. This will further strengthen the Herrenknecht Group's existing portfolio of automated drilling rigs and equipment. Together, technologies "made in Germany" will advance the heat transition.

Two owner-run family companies are combining their expertise: Herrenknecht AG is acquiring two thirds of the shares in H. Anger's Söhne Bohr- und Brunnenbaugesellschaft mbH with retroactive effect from January 1, 2023. The Hessisch Lichtenau-based drilling contractor is well known for safely and successfully drilling several challenging geothermal wells. "An ideal addition to our product range in the field of automated drilling rigs," emphasizes Dr.-Ing. E.h. Martin Herrenknecht, CEO of Herrenknecht AG. "We will use the shared entrepreneurial and engineering DNA to drive forward the heat transition and simplify access to natural resources." 

In Germany alone, 50 percent of heat generation should be climate-neutral by 2030. As a non-fossil energy source with its constant availability, geothermal energy is key to achieving this goal. According to the German government's plans, the expansion and use of this heat source is therefore to be prioritized in the coming years, which will result in a need for new drilling rigs, equipment and drilling services.

H. Anger's Söhne Bohr- und Brunnenbaugesellschaft mbH employs around 150 people. It specializes in drilling geothermal wells to depths of up to 7,000 metres. In addition to geothermal energy, projects are carried out for reservoir and subsurface investigations. The company's main range of services also includes well construction for drinking, mineral and thermal water.
