What type of polyacrylamide is used in oil industry?
The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
Which comonomer is used for the production of anionic polyacrylamides?
The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
What is high molecular weight polyacrylamide (PAM)?
Supplied by Our Company High molecular weight polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction reducer in enhanced oil recovery and high-volume hydraulic fracturing.
What is an anionic polyacrylamide?
Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
