Core preservation and storage
The preservation of the initial rock properties is of fundamental importance for the reliable determination of rock physical and rock mechanical characteristic values in the laboratory. Therefore, a suitable sample treatment immediately from the time of core removal is strictly necessary. For core material containing a significant amount of clay (such as shale), the focus is on adequate protection from drying out to prevent the drill core from irreversible alteration. The Gesteinslabor offers all necessary measures for save core reception and handling to preserve the pre-coring conditions and initial rock properties.
The Gesteinslabor offers a full service of caprock preservation beginning with the take-over of the cores at the drill site, via vacuum-packing of the cores in airtight, plastic coated aluminum bags and within nitrogen filled containers designed for core transport (so-called liners) to computer based documentation and long time storage of the clay(stone) and shale cores.
Additionally we offer the reception, documentation and storage of less delicate drill core material, such as sand- and limestone.

Meet us at the GET 2024
Gesteinslabor will exhibit at the GET2024 in Rotterdam. 4.-7.November 2024, find us at booth 605.
We are looking forward meeting you there!
Gesteinslabor Dr. Eberhard Jahns is project and research partner within the HENRI (Hydrogen Energy Reservoir) project.
Main focus of us is the impact of H2 on the cap rock. Besides other parameters, we determine the capillary threshold pressure with different gases and gas mixtures.
First preliminary results could be presented at the 2nd HENRI conference.
Recently, the article "Determination of capillary threshold pressure with hydrogen gas" was published in the journal EEK.
Article from the journal EEK 01/2023
Gesteinslabor has successfully completed the development of a new test rig to determine the capillary threshold pressure with hydrogen.
