Deep Drilling Rigs

________________ Both oil and gas fields and geothermal energy sources can be explored using deep drilling rigs. The operation of the rigs, however, poses specific demands on the environment and the surroundings. As a subsidiary of Herrenknecht AG, Herrenknecht Vertical specializes in the construction of deep drilling rigs, which are individually designed and manufactured to customer specifications. The Terra Invader type deep drilling rigs can be used for onshore and offshore drills to depths of down to 8,000 meters.
