Water-soluble polymers have been widely used in the oil and gas industry due to their unique features such as ‎enhanced rheological properties and high thermal stability. Water-soluble acrylamide terpolymer ‎nanocomposites modified with hydrophilic groups of maleic anhydride and hydrophobic groups of styrene ‎containing silica nanoparticles were synthesized using in-situ terpolymerization and its rheological properties ‎were studied. The morphology and particle size of the terpolymer and silica nanoparticles were measured using a ‎field emission scanning electron microscopic (FE-SEM). Rheological behavior of terpolymer and ‎nanocomposites solutions including viscosity, complex viscosity and storage modulus at different temperatures ‎as well as in the presence of different concentration of NaCl, MgCl2 and CaCl2 salts were studied using ‎rheometric measurement system (RMS). The results illustrated that with an increase in temperature as well as ‎increase in salts concentrations, the viscosity increases considerably. The unique results obtained from the ‎rheometery test showed that the synthesized nanocomposites can be used in applications with high temperatures ‎and high salinity environments.‎
