C20 LINKED POLYMER SOLUTIONS FOR IMPROVED OIL RECOVERY BY WATERFLOODING Abstract 1 MORTEN G. AARRA MAGNY BJØRSVIK HARALD HØILAND TORE SKODVIN DAG STANDNES AND ARNE SKAUGE Centre for Integrated Petroleum Research CIPR University of Bergen Bergen Norway Polymer gel treatments have been widely used to improve sweep efficiency or to reduce production of unwanted water. In this study we have focused on identifying systems for in-depth mobility control to increase sweep efficiency during water flooding. The systems are sometimes referred to as linked polymer systems (LPS) or colloidal dispersion gels (CDG). LPS can be a useful EOR method for oil
