Laboratory equipment includes a unique setup X-ray Tomography “Phoenix V | tome | V S240” and filtration device “Wille Geotechnik”.
Research is aimed at creation of a mathematical model of multiphase multicomponent liquid filtration, considering physico-chemical effects on the porous medium; the model will use parameters obtained through analyzing tomography studies of cores (carbonate, dolomite, etc.), such as a porosity, absolute permeability, tensor permeability, pore size distribution; experiments on chemicals effects (acid, polymers) on different cores, as well as process analysis and visualization using X-ray tomography; comparison of results obtained through numerical simulation with experimental results.
Plans for 2015-2016 include:
1) creation of a software package simulating flow of viscous fluid in digital core and calculation of its main filtration characteristics (updated Russian analogue of import software AVIZO FIRE Xlab Hydro);
2) fine-tuning of experimental techniques for filtration testing on cores of different nature, including pumping of acids, bases, polymers and coolants; process imaging in X-ray tomography;
3) building of mathematical models describing reacting liquid flow in a digital image of the core and verification of these models on the basis of experimental data.
