  • What is polyacrylamide (PAM)?
  • This chapter discusses polyacrylamides (PAM). Among the various polymers that have been studied for chemical enhanced oil recovery, PAM is most important. PAM is used frequently for mobility control as well as permeability control. PAM (and its modified forms) is the principal polymer used in significant amounts on a commercial basis.
  • What type of polymer is Pam?
  • PAM (and its modified forms) is the principal polymer used in significant amounts on a commercial basis. Usually, anionic versions of PAM are used rather than the nonionic homopolymer itself. By far, poly (acrylamide- co -acrylic acid) is the most common, and the nomenclature PAM/AA is used in this chapter to refer to this group of polymers.
  • Why is Pam/AA a good polymer?
  • Thus, the end result is a reduction in the permeability to the displacement fluid. According to equation (8-1) this serves to improve the mobility ratio. The retention property is distinctive of PAM/AA. It represents an advantage of PAM/AA over the other major EOR polymer, i.e., xanthan gum.
  • What is the rate of dissolution of Pam?
  • The rate of dissolution of PAM and any high-molecular-weight polymer is usually slow, especially in poor solvents or brines. Liquid polymers, other than emulsions, are easier to dissolve. The transportation cost, however, tends to be high because of the low polymer concentration (5% or less).
