Polymer Flooding for Mature Oilfields

In fields that have been on waterflood for years, injected water fingers through high-permeability streaks and leaves oil behind. Dissolving 800–2,000 ppm of high-MW HPAM raises water-phase viscosity, improves the mobility ratio and pushes the remaining oil bank towards producers. We match molecular weight and hydrolysis to reservoir temperature and brine salinity, then verify with rheology and core-flood data from our lab.
