DCM
The Dielectric Constant Measurement technique (DCM) is a fast, easy and cheap method to determine the amount of swellable clay minerals within a sample and indirectly the angle of internal friction. This knowledge is of crucial importance for drilling progress, wellbore and caprock stability, as well as the frackability of unconventionals, because the presence of clay minerals with interstitial water lowers the strength of a rock significantly.

DGMK/ÖGEW spring conference 2025 goes on tour and we are part of it!
Meet us on booth 2, we look forward to a lively exchange in Papenburg.
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.
