  • 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.
  • What is partially hydrolyzed polyacrylamide (PHPA)?
  • Partially hydrolyzed polyacrylamide (PHPA) is the most frequently used polymer in this respect, owing to its low cost, viscosifying nature, and well-known physiochemical properties (Urbissinova et al. 2010 ). The molecule of this polymer is a flexible chain which remains in coil-like structure in the absence of a shearing effect.
  • 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.
  • What is a PHPA molecule?
  • The molecule of this polymer is a flexible chain which remains in coil-like structure in the absence of a shearing effect. The application of PHPA is limited due to high temperature and salinity (Uddin et al. 2002 ).
