ALS’ helical CT scanner is a non-destructive tool that uses powerful x-ray photons to create a 3D model of a sample. Data acquisition can be undertaken on whole core, slabbed core, and plug samples, regardless of preservation. It facilitates rapid inventorying, digital rock modeling, fracture analysis, and determination of bedding orientations.
Benefits:
• Rapid acquisition of data regardless of sample preservation
• Valuable first-look analysis that can be utilized in digital rock models
• Variety of scan protocols tailored to client needs
• Helical CT data can be used for:
• Bedding Detection
• Fracture Analysis
• Orientation
• Type
• Storage
• Mineral Fill
• Plug Selection
• Pore Geometry
• Gas Hydrate Dissociation
Deliverables:
• Raw DICOM files for import into 3D visualization software
• Movie animation of the axial interior of core sample
• Integrated core report displaying the following views:
• Longitudinal Image
• Cylindrical Unwrapped Image
• Three Axial Slices
Specifications:
The following scan protocols are available at 250 μm voxel size resolution:
• Balanced Core – Standard resolution scan that is sensitive to contrasting densities with good spatial resolution. This protocol is ideal for matrix and grain characterization, as well as correlation with density logs.
• High Resolution Core – Scan protocol that provides high spatial resolution with fair density resolution. This protocol is ideal for porosity characterization, as well as structural analysis of fractures.
• High Resolution Plug – This scan protocol is used primarily for visualization of plug samples before and after testing. It provides high spatial resolution and fair density resolution.
