DEEP DIVE WORKSHOP SERIES

Did you know that you can use CT for modeling and simulations? In this Deep Dive series, we will run three episodes over a three-month period to cover a specific topic and take a deep dive into it. In this first episode of "Digital Rock Analysis" Deep Dive, we will review how to collect high-quality CT images of a drill core that can be used for digital rock analysis. Register for this virtual workshop. You can watch it live and ask questions, or watch the recording later.

Digital Rock Analysis

In this series, we will take a deep dive into digital rock analysis. This is a three-part monthly workshop; 1 - Data collection, 2 - Segmentation and property analysis, and 3 - digital rock simulations.

Presenter: Aya Takase | Co-presenter: Angela Criswell | Host: Tom Concolino

1. Data collection

There are many data collection parameters to consider. The X-ray voltage and filter contribute to the image contrast and beam hardening artifacts. The scan time affects the signal-to-noise ratio. And the resolution needs to be carefully selected to run accurate simulations. In this episode, we will go into the lab and compare different data collection settings. Then we will review how to collect high-quality CT images of a drill core that can be used for digital rock analysis.

When: Wednesday, July 13, 2022, at 1 PM | CDT

In this workshop, you will learn:

  • How to assess the resolution required for digital rock analysis
  • How to collect high-quality CT images of drill cores
  • How to evaluate the image quality for digital rock analysis

2. Segmentation and property analyses

Image segmentation, or labeling of all voxels, is the first step of the analysis. There are different techniques you can use for segmentation. Once the image is segmented into different phases, we can start analyzing basic properties, such as porosity and the ratio of open and closed pores. In this episode, we will review image segmentation, and calculate the basic properties of rock samples.

In this workshop, you will learn:

  • How to segment rock CT images
  • How to analyze basic properties, such as porosity and the ratio of open and closed pores

3. Digital rock simulations

When the CT image of a rock sample has sufficient resolution and is segmented well, we can simulate the flow characteristics of the rock and obtain permeabilities and visualize the percolation path, flow field velocity, etc. In this episode, we will look into how we can run these simulations.

  • How to calculate capillary pressure curves
  • How to obtain relative permeabilities
  • How to simulate drainage and imbibition processes

Filtration Analysis

In this series, we will take a deep dive into filtration analysis. This is a three-part monthly workshop; 1 - Data collection, 2 - Segmentation and property analysis, and 3 - filtration simulations.

Presenter: Angela Criswell | Co-presenter: Aya Takase | Host: Tom Concolino

Filtration analysis of masks

1. Data collection

Filtration analysis using CT investigates a wide range of materials from filter media to complete filters. Because of the range of materials and sample sizes, data collection must be carefully considered. For example, samples may require either micro or nano-scale imaging to achieve sufficient resolution of filter materials. In this episode, we will go into the lab to investigate how to choose the best data collection geometry and data collection parameters. Then we will review how to collect high-quality CT images of filter media that can be used for digital filtration analysis.

In this workshop, you will learn:

  • How to collect high-quality images of filter media 
  • How to evaluate your filter media data and assess suitability for fiber analysis 

2. Segmentation and property analyses

Image segmentation, or labeling of all voxels, is always the first step of the analysis and there are many different techniques to perform segmentation. Once the image is segmented, we can start analyzing the basic properties of filtration media and devices. These analyses will include characterization of media, whether the media be fibrous or other material. For example, we can calculate filter component size, orientation, volume percentage, and other parameters. In this episode, we will review image segmentation. Then, we will calculate some basic properties of filter samples and prepare data for simulations.

In this workshop, you will learn:

  • How to identify and separate fibers 
  • How to analyze fiber properties, including fiber diameter, orientation and curvature

3. Filtration simulations

When the CT image of filter material has sufficient resolution and is segmented well, we can simulate flow through filtration materials to determine filter efficiency and to analyze filter clogging and lifetime. In this episode, we will investigate how we can run these simulations.

  • How to simulate the filtration process for filter media 
  • How to track particles during filtration simulations 
  • How to examine filter efficiency and filter lifetime
