| Development of carefullydesigned glass and geomaterial microfluidic systems | Development of microfluidic systems: (a) glass micromodels with high-, moderate-, and low- reservoir quality for homogenous matrix cases, heterogeneous matrix cases (patchy, layered, random sizedsystem), and mixed matrix-fractured cases; (b) geomaterial micromodels with high and low reservoir quality sandstones representing both single- and dualporosity-permeability cases. | University of Oslo | 1 | 18 | Finished |
| Construction of microfluidic system and adaptation of spectroscopy methods in the analysis of chemical and physical properties of reservoir fluids. | This task focuses on developing state-ofthe-art microfluidic Raman laboratory. This laboratory will be capable co determine properties such as CO2 concentration, saturation curve, minimum miscibility pressure and equilibrium phase curves. UO will fabricate microfluidic systems. AGH will be responsible for designing, construction setup and performing experiments. | University of Oslo and AGH UST | 1 | 24 | Finished |
| Analysis of chemical change of water/brine/CO2 and Water/brine/CO2/rock (reaction in simulated conditions with rocks) | Analysis of the impact of chemical reaction between CO2, water, brine and rock measurements will be conducted on the conventional multiphase laboratory („Core Lab”/”Sandler”). | AGH UST | 12 | 30 | Finished |
