Revisiting polymer selection workflows for chemical enhanced oil recovery

2023. EAGE IOR+ The Hague.

The workflow used to select and study polymer candidates for polymer flooding has remained relatively unchanged since the first projects were performed in the 1960s. Starting with viscosity curves and filtration test, the polymer candidates are then injected into cores representative of the reservoir from which parameters are extracted for history matching and simulation purposes. Interestingly, all studies follow the same book without questioning the validity of the approaches used or the representativity of the polymer solution studied.
