About Daldrup & Söhne AG
Daldrup & Söhne AG is a publicly listed drilling company headquartered in Oberhaching near Munich with a branch office in Ascheberg (Westphalia). Its broad project portfolio includes the planning and execution of shallow and deep geothermal drilling, hydrothermal doublets including completion as production and reinjection wells, exploration and reconnaissance drilling for raw material deposits and subsoil, well drilling for drinking, process, mineral, healing water and thermal brine, as well as technical environmental services and special civil engineering. Further services include workover and backfilling of decommissioned wells, cementations, shaft stabilisation and drilling work in contaminated areas. The equipment fleet ranges from deep drilling rigs with hook loads of up to 350 tonnes (Bentec Euro Rig DS-10, wells up to 6,000 m) via the City Rig and numerous Wirth, Nordmeyer and Geotec drilling units to dry drilling rigs for bores up to 2,000 mm in diameter. Customers include utilities, municipalities, tunnel and infrastructure projects as well as greenhouse and geothermal companies in Germany, the Netherlands, Belgium, Austria and Switzerland; it has its own subsidiaries, GERF B.V. (Netherlands) and Daldrup Bohrtechnik AG (Switzerland).
