Digital Core Analysis with GeoDict 2023 – Latest & Greatest

Digital Core Analysis represents the digitalization of Routine and Special Core Analysis (SCAL) based on the Digital Rock Physics (DRP) concept. With the maturing of the technique, the digital workflows now shift from research and development (R&D) to exploration and production (E&P). This goes along with requirements for efficiency, reliability, and workflow automation. The professional software suite GeoDict tackles these challenges and provides the cutting-edge technology needed for a reliable prediction of reservoir rock parameters as part of E&P workflows in cloud environments.

The typical DRP workflow begins with 3D image processing and segmentation of 3D gray value images of reservoir rocks obtained by a variety of image acquisition devices. Based on the resulting voxel-based geometry, the pores, grains, and fractures of digital rocks are characterized. For SCAL digitalization, the determination of transport properties in digital reservoir rocks is a key capability. The GeoDict software package predicts the absolute permeability of porous and microporous reservoir rocks, computes capillary pressure curves in mixed-wet systems, and determines the relative permeability curve. Further features are amongst others the determination of electrical properties and of overall mechanical properties, and the incorporation of geochemical reaction capabilities for CO2 sequestration setups.

Latest developments include the single-phase Darcy solver for determination of whole-core absolute permeability during multi-scale workflows, GeoDict SaaS cloud environments, and more.
