Study of salt tolerance and temperature resistance of a

The influence of salt and temperature on the viscosity of a hydrophobically modified polyacrylamide-based (PAM-based) novel functional polymer (RH-4) was investigated. To study the viscosifying mechanism in brine solution, scanning electron microscope (SEM) was applied to observe the network microstructures of polymer solution.

Experimental evaluation of partially hydrolyzed

The chemical EOR is one of the techniques for the increment in oil production. Chemical flooding using water-soluble polymers like partially hydrolyzed polyacrylamide (PHPA) has been industrially used as an EOR technique. The paper deals with the effect of nano-silica particles on viscosity as well as the shear rate of the polymer solution.

The values of ϕ1 and ϕ2 for salt-free PHPA as well as PHPA with different salt concentrations are presented in Table 2. These results were obtained by solving equation 3 and 7 using Mathematica software. The hydrolysis was influenced by the presence of salts and the predictions of equation 3 were lower than experimental data.

Polymers for Enhanced Oil Recovery - Energy & Resources

When long term stability in highly saline brines at moderate to high temperatures is required, the stability of standard polyacrylamide sodium acrylate copolymers (Aspiro™P 42XX series) against hydro- lysis and degradation might not be sufficient. In this case BASF offers the range of sulfonated polymers (Aspiro™P 54XX).
