A group of Kemira’s R&D experts ran a series of experiments to study what happens to the polymer during polymer flooding, and how the back-produced polymer behaves in the surface facilities, depending on time, temperature, and polymer and brine compositions.

In this 16-minute presentation, our Research Scientist Brita Peltokoski explains how the polymer’s chemical properties change in the reservoir, and how the consequent precipitation risk can be mitigated already in the polymer selection phase.

The results of the research were first presented at the 30th Oil Field Chemistry Symposium, organized by The Norwegian Society of Graduate Technical and Scientific Professionals in March 2019. The presentation was awarded by the organizer as the best scientific paper of the symposium.
