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.

The DGMK/ÖGEW spring conference is on the road for the second time, and – as always – we’ll be there!
Come and see us in Münster at Stand 32 on the upper floor; we look forward to seeing you!
Gesteinslabor Dr. Eberhard Jahns is project and research partner within the HENRI (Hydrogen Energy Reservoir) project.
Our main focus is on determining the impact of H2 on the cap rock. Besides other parameters, we measure the capillary threshold pressure using various gases and gas mixtures of hydrogen and methane.
Results were presented at the third HENRI conference in Bratislava in September 2025
We are pleased to be part of the Dutch subsurface research for geothermal heat SCAN.
