The upscaling procedure is tested over a range of injection rates spanning three orders of magnitude.
A wide range of injection rates was trying to examine the reservoir performance under the miscible CO2-injection.
The range of injection rates assigned to the model boundaries (q i1 and q i2, as shown in Fig. 1b) was 50 150 m3/day (Kim et al. 2010).
It has been shown that, among the gases investigated, CO2 is the best choice from the thermal-hydraulics viewpoint, being able to cool the core satisfactorily for a broad range of injection rates.
With the purpose of studying the effect of injection rate on foam mobility control ability, three series tests (runs 4 6) were designed in which injection rate ranged from 0.5, 1, 2 mL/min.
(b) SCW temperature increases with increasing of injection rate.
(b) SCW enthalpy increases with increasing of injection rate.
At the given range of gas injection rate, the critical light oil rate will increase with the increase in gas injection rate, at approximately 20 40 m3/day.
However, the injection efficiency is related not only to the variation range of injection pressure and injection rate but also to the variation rate of injection pressure and injection rate.
It is found that field scale simulations of transport processes without including the dispersion in fractures are not valid for the whole range of practical injection rates (104 < Pe < 106).
