CoreHD® Whole Core High-Definition CT Scanning and Logging
CoreHD® Continuous Core Viewer
CoreHD® is Ingrain's breakthrough technology platform for high-definition CT scanning and logging of whole core. Ingrain has developed a fully integrated workflow that allows geoscientists to rapidly evaluate whole core to identify lithofacies or rock types and thereby optimize sampling locations for basic and advanced rock properties analysis.
CoreHD® Suite for Whole Core Logging
Combined with Ingrain’s proprietary image processing capabilities, Ingrain offers the CoreHD® Suite, including the Continuous Core Viewer, the CT Borehole Image, and the CT Density and Atomic Number Log. The Continuous Core Viewer shows over 1500 digital cross-sections per meter of core. The CT Borehole Image that is similar to the kind of wellbore image that can be obtained from wireline logging. The specialized CoreHD image acquisition allows Ingrain to compute a Density and Atomic Number Log.
1. Continuous Core Viewer
The Continuous Core Viewer shows over 1500 digital cross-sections per meter, with a well bore-axis 2D image of the whole core to show the location of the image being viewed. This density-based image provides definitive data to optimize sample selecting for rock properties analysis.
2. CT Borehole Image
Having imaged the whole core in 3D, Ingrain uses image processing software to extract a cylindrical view of the core, which is then digitally “unfolded” and provided in the format of a borehole image log. At .625 mm voxel resolution, the CT Borehole Image has higher resolution than borehole image logs. The CT Borehole Image can be extracted from various depths inside the 3D volume to avoid mechanical damage that might be present on the surface of the core.
3. CT Density & Atomic Number Logs
Based on X-ray attenuation, density and atomic number are derived for each voxel and calculated for each cross-section. A log is plotted showing the values for each cross-section.
When used on the entire whole core from a well, the CoreHD® Suite can be used to characterize rock types and flow units. This enables fast, accurate optimization of the number and location of core plugs for advanced rock properties analysis. Once the core plugs are selected, Ingrain can quickly image and compute accurate basic and advanced rock properties using its proprietary technologies for scanning, image processing and high performance computing.
CoreHD® high-definition CT scanning creates a permanent digital record of the whole core (ideally before slabbing or other destructive tests) that can be shared easily by the entire asset team.
