... of polymer in real time. The results showed that only three polymers can be dissolved at 227500 mg/L salinity and 23 °C (reservoir temperature) and give homogenous solution with the viscosity of higher than 100 mPa·s at the polymer concentration of 2000 mg/L. CBHB showed the highest viscosity of 830 mPa·s...
