... of the system is in general time-varying and contains non-linearities or non-linear components. Examples of system inputs are fluid injections (flow rates of injected species) and wellhead choke valve settings (pressure and/or flow rate control); outputs typically consist of the production fluid flow rates (oil...

.... The injection platform (see Figure 1.c ) is equipped with eight pumps and is fully automated allowing the control and monitoring of different parameters (absolute and differential pressure, temperature, flow rate…). To infer the oil saturation from the radiographs, we use Beer Lambert's law for multi...

... Injection is implemented by changing the sign of the total flow rate (positive for injection). All production wells are assumed to produce at the same phase flow rates, while the injection well injects only water. Schematic of the pattern for case 3 is shown in Fig. 9 , where the boundaries...

..., the emulsion viscosity was 12 cp at 373 K, at which the bitumen viscosity was 273 cp. The efficiency of in-situ bitumen transport was evaluated by calculating bitumen molar flow rate under gravity drainage with the new experimental data. Results show that oil-in-water emulsion can enhance in-situ molar flow...

... for studying mechanical degradation at different flow rates as a function of distances travelled. The set-up enabled us to evaluate degradation in serial mounted core segments of 3, 5, 8 and 13 cm individually or combined. By recycling we could also evaluate degradation at effective distances up to 20 m...
