The largest of these drill core repositories is located in the Grubenhagen branch (please see below how to find us). On approximately 2,000 pallets, about 40,000 running meters of drill cores are stored in pallet racks.

In a newly built storage hall at the Geozentrum in Hannover there are approximately 18,000 running meters of drill cores, also stored in pallet racks.
At its two sites in Hannover and Grubenhagen near Einbeck, the BGR uses its core repositories together with the LBEG (Landesamt für Bergbau, Energie und Geologie, State Authority for Mining, Energy and Geology).

Further 50,000 running meters of drill cores are stored in the Berlin-Spandau branch. This storage is spatially connected to the National Core Repository for Continental Drill Cores.

The major part of the drill cores in our core repositories originates from Lower Saxony’s underground, including drillings in the North Sea, the North-German Lowland, the Weser Hills and the Harz mountains. Also the drill cores of the 7,000 m deep drilling of „Boitzenburg“, the deepest borehole ever drilled in Lower Saxony, are stored in our core repository in Grubenhagen. Many drill cores originate from other German regions and from other countries (amongst them also drillings from countries like Russia and Yemen).

From practical goals to research purposes, the objectives of those drillings cover a wide range. For many of them, it was the prospecting of energy and mineral resources. But there are also numerous drill cores from programs aiming at defining sites suitable for landfills, or from geothermal energy and research projects.
In addition to this, around 70.000 single samples of drill cores from Northwest Germany and other regions are kept in the geoscientific collection Hannover. These originate for example from deep drillings searching for mineral oil or from bores for iron ore exploration. Until around 1965, evidence material of drill cores which do not exist anymore, originating from about 4,000 drillings, was stored in the Hannover collection.

The core sample collection in Berlin contains processed specimen samples from more than 5,000 drillings, all of which were drilled between 1872 and 1973 on German and former German territory or in border areas of neighboring countries such as Austria and the Czech Republic. A special feature are the samples from the "Reichsbohrprogramm", a drilling program aimed at hydrocarbons.
