Among the methods available to reduce water production, during oil recovery injecting a gelling
system composed of a polymer and a crosslinker has been widely used. In this study, a Plackett-
Burman design was used for screening a large number of factors such as concentration of polymer,
crosslinker, NaCl, CaCl2, MgCl2, KCl, thiourea, sodium lactate, clay, pH and temperature on the
gelation time of sulfonated polyacrylamide gel by rheological tests. Among these factors,
temperature, pH and CaCl2 concentration were found to have the main effects on the gelation time.
Then the effects of these three factors and their interactions on the gelation time were determined
by a method response surface methodology, central composite design. It was found that
temperature was the most effective parameter to control gelation time and this property increased
by increasing pH up to 7 and decreased by further increase of pH.
