Poly(acrylic acid) (PAA) samples with molecular weights between 820 and 2950 were synthesized by a solution
polymerization process using an initiating redox system. The obtained PAAs were then screened for their ability to inhibit salt
scale formation. In this screening system, salt scale was formed by injecting pit water into the oil. The salt scale inhibition
efficiency was higher for PAAs at a higher concentration and for lower molecular weight PAAs. A reduction of pH, extension of
stirring time, or an increase in temperature caused the inhibition efficiency of the PAAs to drop. An optimal inhibition efficiency
of 98.70% was observed using a PAA with a molecular weight of 820 at a concentration of 20 ppm, at 20 °C, while being stirred
for 1 h at a pH of 6.029.
