  • Which molecular weight is suitable for flooding in low permeability reservoirs?
  • Therefore, a molecular weight of 1100*million of HPAM can get the highest enhanced oil recovery. This indicates that a molecular weight of 1100*million of HPAM is suitable for the flooding in low permeability reservoirs. 4. Residual oil distribution in micro-displacement experiment
  • Can hydrolyzed polyacrylamide be used for displacing reservoir oil?
  • This research evaluates performance of an acrylamide-based polymer which can be used for displacing reservoir oil. Three associated polymeric systems were proposed based on hydrolyzed polyacrylamide (HPAM), reported PAAHO, and the novel syn- thesized and characterized functionalized copolymer PAAHAI.
  • Why is chemical flooding technology important in oilfield exploitation?
  • With the development and application of water flooding technology in low permeability reservoirs, at the later stage, the excessive water cut and the low oil recovery is inevitable. Therefore, it is of great importance to apply chemical flooding technology in the oilfield exploitation.
  • Which polymers are used in enhancing oil recovery?
  • PAM and HPAM are the most extensively used polymers in enhancing oil recovery due to their customized properties and wide availability.
