A New Methodology for Integrated 3D Geologic Reconstruction and Fracture Network Modelling using Outcrop Scan Datasets

A new methodology and workflow are presented for the 3D interpretation and modelling of datasets such as 3D scans on geological outcrops, caves and mines. The unique workflow permits to integrate the results of data analyses and geologic knowledge obtained, to generate a full 3D geological model, and to simulate a data-driven 3D model of the fault and fracture network which fully comprises the on-site observations. An example is presented where the workflow is applied to an outcrop of a stratified, fractured and faulted limestone. Implications will be highlighted for ongoing applications in mining, and subsurface modelling for geofluid exploitation, extraction, and storage (e.g., Oil and Gas, CCUS, H2, Geothermal Energy).
