Automated Petrography: High Throughput Mineral Classification Using Machine Learning

May 14, 2020 | 1:00 pm CDT

Speakers: Kyle Crosby & Matt Andrew
 
One of the biggest challenges in the microstructural characterization of geological media is that of scale. Optical petrography has been the mainstay for such large-scale analyses, requiring the manual measurement and quantification of mineral, crystal, and grain structures indicative of geological processes. This has historically required the exacting, arduous work of trained specialists, a process which has proven extremely difficult to scale using traditional computational techniques coupled with automated imaging. We will review recent developments in automated geological microanalysis, coupling automated multi-polarized slide handling and image acquisition with advanced image processing and machine learning based pixel classification. Further, we will illustrate how these machine learning models can be either trained manually or correlated with SEM based AQM to allow for automated mineral training.

Key takeaways:
  • Automated high throughput petrography can complement traditional geological microanalysis techniques, scaling analyses over many samples to allow local micro insight to be understood relative to geological heterogeneity
  • Digitization enables and improves geological teaching because it allows for petrography to be accessed as digital data assets while simultaneously reducing institutional data loss through improved archiving
  • Machine learning classification tools coupled with powerful image processing and analysis software can be correlated with existing state-of-the-art Scanning Electron Microscopy (SEM) based Automated Quantitative Mineralogy (AQM) tools

Further Understanding Structure, Evolution, and Degradation in Electrochemical Systems

May 27, 2020 | 10:00 am CDT

Speakers: Will Harris & Robin White

In Part 2 of the series on energy materials, we begin with a look at another important electrochemical system, fuel cells. The broad domain of fuel cells includes a variety of systems consisting of very different materials and operating challenges. In this workshop we will primarily highlight two common classes, the low-temperature polymer electrolyte membrane (PEM) fuel cell and the high-temperature solid oxide fuel cell (SOFC), along with their associated materials characterization requirements.

We will also consider lifetime and performance degradation of electrochemical systems in general, and consider ways that we can use in situ imaging techniques to observe changes or evolution behavior through system operation.

Key learning objectives include:

  • Understand microscopy methods to characterize complex 3D microstructures which influence factors like gas diffusion pathways and triple phase boundaries
  • Coupling imaging to segmentation, quantification, and even modeling of the image data
  • Using in situ or time-lapse imaging techniques to understand how structures evolve over time during the course of operation or stimulus

From nm to mm: Covering Lengthscales in Imaging and Fabrication with the New LaserFIB

June 9, 2020 | 10:00 am CDT

Speakers: Will Harris & Kyle Crosby

Focused ion beam-scanning electron microscopes are well established for sample analysis and preparation at the nano- to micro-scale in 2D, 3D or even 4D (with analytics). However, for investigations extending to larger scales of hundreds to thousands of microns, FIB-SEMs have faced a challenge. This has included tasks like large cross-section preparation for imaging/EBSD, or creation of structured geometries for micro/nano-mechanical testing. In Part 2 of this series on engineering materials, we present the LaserFIB, a new instrument platform to address these gaps. The LaserFIB integrates a femtosecond-pulsed laser into a FIB-SEM, now offering machining capabilities from the nano to millimeter scale on a single platform. The ultrashort laser pulse duration minimizes heat damage, and laser milling is performed in an isolated chamber to avoid main chamber contamination. Combined with imaging and analytics (EBSD, EDS), this platform offers tremendous opportunities for rapid, multi-scale material analysis and targeted, sub-surface investigation.

Key learning objectives include:

  • An introduction to the LaserFIB, and how it compares to alternative technologies
  • How, through targeted massive material ablation, the LaserFIB opens the door for entirely new studies that were not previously possible
  • Understand typical workflows in engineering materials by way of several examples in cross-sectioning and sample preparation

Solving Petroleum Problems Using the Frontiers of Imaging Technology: Multiscale, Correlative and in situ Techniques

June 16, 2020 | 10:00 am CDT

Speakers: Kyle Crosby & Edward Hill

Pore scale imaging has developed over the last 20 years whereby it is now possible to routinely image, both in 2D and 3D, structures and processes occurring from the whole core down to the sub-nanometer scale. This type of characterization using automated and correlated light, electron and x-ray datasets can be used as the input for computational simulations or integrated for in situ experiments in the lab. The challenge of scale can be addressed by the spatial correlation of high-resolution structures and microfluidics with macro-scale heterogeneity. Local insights can then be upscaled back to the core-plug scale using macro-scale rock type maps, generated using machine learning based computer vision tools. We will review how pore scale imaging can be used within the Oil and Gas community, focusing on three major applications; digital core analysis, multiscale rock characterization, and automated optical photography.

Key takeaways:

  • Core Analysis involves the non-invasive 3D multiscale and in situ imaging of pore structures and fluids for the petrophysical characterization of reservoir rock
  • Rock characterization allows for the multiscale characterization of pore and mineral structures from the cm down to the sub-nm scale, both in 2D and 3D
  • Automated optical petrography uses a combination of automated robotic acquisition and machine-learning computer vision to characterize pore and mineral structures for subsequent prediction of flow properties

ZEISS Mineralogic: Quantitative Geochemical and Petrological Analysis

July 7, 2020 | 10:00 am CDT

Speakers: Kyle Crosby & Richard Taylor

The Scanning Electron Microscope (SEM) is the most prolific piece of analytical equipment in the Earth Sciences, therefore quantitative mineral chemistry obtained directly from the SEM has the potential to streamline many geological fields. Mineral chemistry provides direct constraints on geological processes, as a result major element analyses of rock forming minerals have been one of the major contributors to geochemistry for decades. Electron beam techniques have been the most widely used method of obtaining in situ major element chemistry, dominated by the quantitative Wavelength Dispersive Spectroscopy (WDS) employed by the Electron Probe Micro Analyzer (EMPA). More rapid, and typically more qualitative Energy Dispersive Spectroscopy (EDS) major element measurements can easily be obtained on a standard SEM instrument. Although automated EDS mineral mapping via SEM has remained essentially unchanged for decades, with an experienced operator required for many of the analytical tasks, ZEISS Mineralogic Automated Quantitative Mineralogy (AQM) takes a new approach following an analytical protocol more closely aligned with EPMA. A combination of matrix corrections, peak deconvolution, and standard calibration allows peak intensities to be converted into wt% element directly at the time of analysis. The result is a data output that can be immediately interpreted, even for minerals not previously analyzed, by both new and experienced users. We will demonstrate the use of the ZEISS Mineralogic system for mapping thin sections from high grade metamorphic rocks with greater speed, accuracy, and flexibility than has previously been possible.

Key takeaways:

  • ZEISS Mineralogic is a unique analytical SEM, combining automated mineral mapping with quantitative geochemical analysis
  • AQM allows for bulk sample chemistry to be obtained at any scale within a petrographic thin section
  •  Standard calibrated quantitative EDS can allow geological conditions to be constrained with direct context to petrographic observations

After focusing primarily on metallic systems in Parts 1 & 2 of this series, Part 3 will shift the focus to advances in other engineering materials, namely ceramics, composites, and cementitious building materials. The heterogeneity and often complex microstructures found in these systems present their own set of challenges for understanding structure-performance-property relationships. In this workshop, we evolve beyond classic metallography techniques to new ways that we can apply our toolkit of microscopy methods to better study this diverse class of increasingly important material compositions.

Key learning objectives include:

  • An introduction to the diversity and uses of advanced engineering materials
  • Ways to apply microscopy to understand the effects of their typically heterogeneous structures across length scales and multiple dimensions (2D, 3D, 4D)
  • Image processing, visualization, and quantification examples
