Gel syneresis is a common problem in gel treatment for oil recovery applications. In this study, a stable gel was prepared in a soft brine by using a water-soluble phenolic resin as a crosslinker, nanoparticles as a stabilizer, and partially hydrolyzed polyacrylamide (HPAM) or copolymers with different contents of 2-acrylamido-2-methylpropane sulfonic acid (AMPS) groups as polymers.,Influence of syneresis on permeability reduction by … ,Syneresis is commonly believed to be incompatible with the application of polymer gels to reduce the permeability of porous media. In this paper it is shown that although the permeability of a gel-treated porous medium does increase as syneresis proceeds, the degree of permeability reduction in cores remains technologically useful even when 95% syneresis is observed in bulk samples.,Mechanism of sodium tripolyphosphate inhibiting the … ,Experimental investigations have been conducted to elucidate the mechanism of sodium tripolyphosphate (STPP) inhibiting hydrogel syneresis with respect to the reaction between STPP and partly hydrolyzed polyacrylamide (HPAM). Viscosity measurements indicate that STPP can increase the viscosity of HPAM.
