LMI-BIB-SEM
Additional information regarding our LMI-BIB-SEM technology
How
During Liquid Metal Injection (LMI) the fusible alloy intrudes and fills the connected pore network. The degree of percolation depends on the critical pore throat diameter in the porous medium. The minimum pore throat diameter which can be filled depends on the injection pressure, following the Washburn equation. After the desired injection pressure is reached, the sample is cooled down under pressure and the metal solidifies in the pores. The following BIB-SEM investigation allows interrogating the 3D pore network.
Applications
Characterization of the connected pore network at nanometer resolution on a representative sample scale.
ViP – Virtual Petrograph

Porosity and permeability assessment
LMI resembles conventional Mercury Intrusion Porosimetry (MIP) and therefore we can evaluate MIP data as we visualize what part of the pore space is actually being filled with the liquid metal. Moreover, we can investigate the pore space between the cracks and correct for core damage. Permeability estimation can be obtained relatively easy by using the capillary tube model, as we know the effective porosity and the percolation threshold from the image data.

Rock Salt
Triple-beam Ar-Ion-Milling with a Rotary Stage to Decorate Grain Boundaries and Substructures in Rock Salt
Multi-Scale Imaging and Quantification of Pores in Carbonate Rocks
Characterization of the wide range of pore sizes present in many carbonate rock types requires the integration of optical and electron microscopy. At MaP we developed such a routine in order to capture the porosity in a representative way. At first, automated optical microscopy imaging using the Virtual Petrograph (ViP) allows quantification of the macroporosity. Quantification of the microporosity is obtained by analyzing SEM images recorded from BIB-polished sample cross-sections. Pore space is segmented from the ViP and BIB-SEM image data using advanced image processing algorithms. From the integration of both outcomes we can obtain the porosity, pore size distribution and pore geometry and undertake pore type characterization and classification. Additional Liquid Metal Injection (LMI) followed by BIB-SEM surveys the connectivity of the macro- and microporosity.
Pore Space Quantification and Distribution in an Organic-rich Shale
Physical porosity is a crucial property in shales as it controls the storage capacity to a large extent and forms the transport system. Imaging the visible pore space, the associated mineralogy, and organic matter provide insight into the relevant phases for storage and transport and allow for upscaling. However, it is a challenge to measure the physical porosity in a representative way and at high resolution because of sample heterogeneity as well as small pore sizes, which are typically below the micrometer in those fine-grained rocks. Using our BIB-SEM technology we are able to assess the sample heterogeneity and image the typical pores at nanometer scale resolution, commonly employing a pixel size of 15 nanometer, in a representative way. Moreover, core damage like cracks can be quantified and corrected for bulk porosity and permeability measurements.
Triple-beam Ar-Ion-Milling with a Rotary Stage to Decorate Grain Boundaries and Substructures in Rock Salt
Decoration of grain boundaries in polycrystalline rocks has a long tradition in Structural Geology as in a monomineralic rock the recrystallized grain size is a good indicator for the paleostress conditions. Understanding the mechanical properties of rock salt and its deformation behavior is of major importance for the prediction of long-term stability of nuclear waste repositories, and for our understanding of the dynamics of salt-related sedimentary ba sins which host the majority of oil and gas deposits on Earth. Common methods to expose grain boundaries and substructures in rock salt are chemical etching procedures using brine or water or the gamma irradiation method.

Auto-Vitrinite: Development of an autonomous measuring procedure for the automated determination of fossilized organic matter and thermal maturity of sediment rocks.
We are working on an innovative prototype of a standardized sample preparation protocol, followed by an automated characterization of thermal maturity and additional parameters of sediments based on SEM images.
This project's objective is to establish a systematic and automated measuring procedure for determining the thermal maturity of Vitrinites and parameters for the classification of sedimentary deposits. Our approach is based on a novel preparation procedure using BIB-SEM analysis to replace conventional Vitrinite reflectance measurements. Combined with machine learning algorithms, we aim to introduce a systematic identification of macerals and mineral matter on ion-structured surfaces using the SEM. Generating a constantly growing database, which could be of use to analyze sediment layers, specifically interesting for the oil and gas industry, for nuclear waste storage, CO2 and H2 storage.
This project is implemented as a FuE-cooperation Project with the Institute for Geology and Geochemistry of Petroleum and Coal at RWTH Aachen University. It is funded by the Federal Ministry for Economic Affairs and Climate Action (BMWi)'s "Central Innovation Programme" (ZIM).

GameChanger: Automated carbonate reservoir pore and fracture classification by multiscale imaging and deep learning
Carbonate rocks are heterogeneous at microscopic and macroscopic scales, hence, their characterization is challenging, expensive and time-consuming. Petrophysical analyses cannot provide information on the full geometry and pore space connectivity. Moreover, these analyses are time consuming and require evaluation by experts. Current imaging techniques do not cover a representative range of scales, have difficulty to image microporosity, and are not well integrated with the expert knowledge available. An automated tool for identifying and classifying pores and fractures does not yet exist. This contribution presents a novel multi-scale workflow dedicated to carbonate rocks that integrates innovative methods with state-of-the-art imaging technologies for automated classification of connected pores from nano- to centimeter scale: 1) Virtual Petrograph (ViP), an automated high resolution petrographic microscope to acquire and visualize high-resolution cross-polarized image-maps of ultra-thin sections; 2) Broad Ion Beam – Scanning Electron Microscopy (BIB-SEM), a 2D preparation and imaging technique that preserves the most delicate microstructures and images microporosity in detail over representative areas; 3) Liquid Metal Injection (LMI) followed by BIB-SEM, a porosimetry technique to distinguish connected and unconnected pore space. Validated pore maps will be the input for statistical analysis and used to train deep learning algorithms for pore segmentation and classification.
The project was funded by Shell’s GameChanger program and successfully closed June 2021, see also https://www.shell.com/energy-and-innovation/entrepreneurs-and-start-ups/shell-gamechanger/portfolio.html.

Permea 2: Deformation dependent development of fault zones and the influence of clay smear on the barrier behaviour
Energy storage in the subsurface is primarily influenced by the permeability of the host rocks and its geological constrains. In this project, MaP is working on an innovative prototype of a model for the prediction of permeability in fault zones from microstructural data.
The microstructural analysis by using imaging microanalytical techniques allows the quantification of the fault zones on a cm-nm scale. The focus is on the classification of the elements (building blocks) of the damage zone and the fault core. The porosity (fractures and pores), as well as pore space connectivity, using liquid metal injection in combination with broad ion beam preparation, virtual petrography and scanning electron microscopy, are measured to assign permeability tensors and to model permeability in fault zones.
Project partners are the Johannes Gutenberg-Universität Mainz, IGEM - Institut für geothermisches Ressourcenmanagement, RWTH Aachen University and the Friedrich Alexander-Universität Erlangen.
