Stability
Stability is important for both, reservoir rocks and bore holes. Wellbore stability is crucial to reach the reservoir in general and finally to extract hydrocarbons. It is of particular sensibility in anisotropic rocks, such as shale. With the increasing importance of unconventional reservoirs the topic of wellbore stability will be in the focus of gas & oil industries in the future.
Stability of the reservoir encompasses several problems: wellbore breakouts, sanding, which may lead to the shutdown of a well, and subsidence during or after production, which may damage wide superficial areas on top of a reservoir.
To avoid both, wellbore failure, sanding and reservoir collapse, an intimate knowledge of the geomechanical characteristics of shales and sandstones is essential for the economic success of each oil & gas field development project. Gesteinslabor with its undeniable experience and accuracy in the investigation of clastic rocks can aid in fruitful translation into action of each newly endangered drilling project.

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.
