The two injection scenarios. SP injection consists of a water flooding period followed by polymer (Pol) and surfactant (Surf) injection according to the indicated concentrations. Appendix B, provides details on water injection rates along time due to the competition between the imposed target maximum injection rate on one side, and maximum pressure constraint at the injector on the other side. Note also that Baseline time (04/04/2017) and Monitor time (04/14/2018) are indicated on the time frame.
