WO2014186658A1 - Friction reducer compositions
2020-10-3 · CrudeChem Technologies has supplied friction reducer in 40+ wells between 2019‐2020. Aware of the solidaccumulations due to cations composition in the Anadarko Basin, especially Iron in the Woodford, we brought tomarket a Sodium‐AMPS modified hydrolyzed polyacrylamide. Thepolyacrylamide has been polymerized with AMPSreduce the net charge on the polymer, reduce the polymer molecular weight, and improve compatibility of thepolyacrylamide with cations especially Fe and Ca. FR‐200 anionic polyacrylamide AMPS modified friction reducer,which comes in the form of 30% emulsion has been formulated to perform well in the Anadarko …
