n: a polymer whose basic repeating unit, or rnonorner, is a cornbination of carbon, hydrogen, oxygen, and nitrogen. Polyacrylarnides are used to adjust the viscosity of water slugs during chernical flooding operations. They can also adhere to the walls of rock pores, decreasing the effective permeability of established channels, forcing the injection fluid into new channels, and thus irnproving sweep efficiency.

n: polymer with a high molecular weight. The basic repeating unit or monomer of polyacrylamide is a combination of carbon, hydrogen, oxygen and nitrogen. Polyacrylamides increase the viscosity of the water slug that precedes the final water injection. Polyac

a polymer with a very stable carbon chain. A good friction reducer in small amounts, but the polymer may cause formation damage. Can be used to gel acid, but the polymer will not break.
