  • Can partially hydrolysed polyacrylamide (PHPA) polymer be used in enhanced oil recovery?
  • Polymers are often used as mobility controller for enhanced oil recovery. The present paper deals with the application of partially hydrolysed polyacrylamide (PHPA) polymer in enhanced oil recovery after the conventional water flooding.
  • Can partially hydrolysed polyacrylamide polymer improve oil recovery after water flooding?
  • The present paper deals with the application of partially hydrolysed polyacrylamide (PHPA) polymer in enhanced oil recovery after the conventional water flooding. Experimental results show that viscosity of PHPA solution increases significantly on addition of small quantity of polymer, which in turn decreases the mobility ratio.
  • When did polyacrylamide (PHPA) become available?
  • Partially hydrolysed polyacrylamide (PHPA) became accessible in the foundation industry in the early 1990s (Lam and Jefferis, 2014). Besides, PHPA can be applied in oilfield nowadays, especially in Daqing oilfield, where it is most superior with polymer flooding technique in China (Zhong et al., 2025).
