Definition - What does Polyacrylamide mean?
Polyacrylamide, also known as acrylamide polymer is a polymer that is formed by several subunits of acrylamide. The molecular weight of this polymer is very high. The monomer of acrylamide polymer is made of carbon, hydrogen, nitrogen and oxygen molecules that are combined together tightly making the molecule heavier. It is mainly used as a thickener and a suspending agent. It is also used as a binding agent and stabilizer in lotions.
Petropedia explains Polyacrylamide
Polyacrylamide is abbreviated as PAM and has the chemical formula -CH2CHCONH2-. It increases the viscosity of the water slug that initially flows into an injection well before the final water is injected through this well. Polyacrylamide or acrylamide polymer is used frequently in micellar polymer flooding operations and is considered to be a mobility control buffer. It is largely used in the oil and gas industry to flocculate solids in liquids.
The polymer together with its derivatives is primarily used in water treatment processes as well as in Enhanced Oil Recovery processes, where a highly viscous aqueous solution is generated and injected into the oil well.
