Determination of Absolute Permeability through Simulations
PDF tutorial
Absolute permeability is a key material property for describing fluid transport in porous media, such as rocks or technical structures. Together with porosity, it is crucial for the evaluation and utilization of underground reservoirs.
With GeoDict software, permeability can be precisely calculated using numerical flow simulations. Various physical models are available in FlowDict for this purpose, such as the Stokes, Navier-Stokes, and Brinkman equations. The flow velocity and pressure drop are then evaluated using Darcy's law to determine permeability.
In this PDF tutorial you will learn step-by-step:
- Import and segment 3D scans: Prepare image data using ImportGeo-Vol, noise filtering, and AI-assisted segmentation.
- Calculate permeability: Simulate fluid flow through rock samples with FlowDict.
- Analyze macro- and micropores: Identify and evaluate different pore areas in Doddington sandstone and Estaillades limestone.
- Simulation instead of experimentation: Digital prediction of permeability as a time-saving and cost-efficient alternative to laboratory analysis.
The rock samples shown here were obtained from high-resolution CT scans. The microstructure was precisely segmented using AI to realistically map the pore and solid distribution as a basis for the simulation.
This tutorial is intended for geoscientists, reservoir engineers, and materials analysts who want to digitally determine and evaluate the transport properties of porous materials.
