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.
• 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
• Mineral Fill
• Plug Selection
• Pore Geometry
• Gas Hydrate Dissociation
• 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
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.
