Case Study: Integration of Multi-Sensor Core Logging Data, X-ray and CT Imaging in Ground Model Development

Constructing a robust ground model requires a comprehensive understanding of the area at many scales, from the cm to km scale. This case study, from an area located in a formerly glaciated landscape, presents insights where incorporating cm-scale data from Multi-Sensor Core Logging (MSCL), X-ray radiography, and Computed tomography (CT) imaging data within the integrated ground model helped bridge the gap between geological, geophysical (e.g. seismic data – m to km scale), and geotechnical (e.g. Cone Penetration Testing/CPT data - cm-scale) data sources. The MSCL, X-ray and CT are nondestructive techniques which provide data that can be used to establish correlations to laboratory tests, with the geological interpretation, and enable the prediction of continuous data across the entire core. X-ray and MSCL data are run for all samples, and selected CT scans for higher resolution images. The data set was part of the unitization meetings between the geotechnical and geoscience teams, when refining the soil unit boundaries, and adding detail to the final integrated ground model. The data set was divided into units and sub-units and added more details and ground truthing of the soil and geological formations units in the ground model report.
