As discussed in our post on the Simpleware Physics Modules, our software’s image-based techniques can also be used to calculate effective material properties from scanned samples. This approach is particularly useful when working with porous media or multi-phase composite. A complex heterogeneous material can be substituted with a homogeneous material, whereby effective properties are chosen so that its response to external loads resembles as closely as possible the original material. A built-in finite element solver calculates effective properties and exports results as tensors and fields. Stiffness tensor and elastic moduli can be calculated with the +SOLID module, absolute permeability with the +FLOW module, and electrical conductivity/permittivity, thermal conductivity and molecular diffusivity with the +LAPLACE module.
When using these techniques, it is possible to obtain detailed information on the material properties of rock samples. For example, calculating effective material properties can be useful when analysing scans of different rock types obtained during reservoir characterisation. The intuitive features of the Physics Modules, including convergence graphs to indicate whether obtained results are accurate, and multiple visualisation options, help with analysis of rock samples.
There are many ways in which 3D image data can be used in digital rock physics. Obtaining qualitative and quantitative information from samples provides information that can be used alongside experimental testing of rocks. By integrating multiple digital rock physics tools into a single software environment, we have aimed to make it easier to process and generate models from scan data. With demand growing for digital rock physics workflows to take into account very fine porous structures and more unusual rock types found during exploration, keeping these processes easy-to-use is crucial. The models created in our software are very robust, validated, and capable of being used for different types of rock physics simulations.
