A Review of the Partly Hydrolyzed Polyacrylamide Cr(III

Color changes in conjunction with HNMR are used to monitor chromium acetate hydrolysis, and HNMR is used to characterize Polyacrylamide in solution and to monitor increases of free acetate and decreases of polymer backbone proton and amide proton resonances during gel formation.

Polyacrylamide and partially hydrolyzed polyacrylamide. Polyacrylamide (PAM) is a synthetic polymer of long-chain acrylamide subunits, high molecular weight (1000 to 20 × 10 6 g/mol), and a wide range degree of hydrolysis (Abidin et al., 2012; Joshi & Abed, 2017).

Partially hydrolyzed Polyacrylamide (PHPAM) crosslinked by Cr<sup>+3</sup> is frequently applied to plug thief zone for the better water management in matured oil reservoir. However, PHPAM gel may certainly cause inevitable formation damage nearby the wellbore. Although various kinds of chemical age …
