Studies on behavior of suspension of silica nanoparticle in aqueous polyacrylamide solution for application in enhanced oil recovery

Abstract The viscosity of injection fluid is a critical parameter that should be considered for the design and evaluation of polymer flood, which is an effective and popular technique for enhanced oil recovery (EOR). It is known that the shear-thinning behavior of EOR polymer solutions is affected by temperature. In this study, temperature dependence (25–70 °C) of the viscosity of a partially hydrolyzed polyacrylamide solution, the most widely used EOR polymer for oil field applications, was measured under varying conditions of the polymer solution (polymer concentration: 500–3000 ppm, NaCl salinity: 1000–10,000 ppm). Under all conditions of the polymer solution, it was observed that the viscosity decreases with increasing temperature. The degree of temperature dependence, however, varies with the conditions of the polymer solution. Martin model and Lee correlations were used to estimate the dependence of the viscosity of the polymer solution on the polymer concentration and salinity. In this study, we proposed a new empirical model to better elucidate the temperature dependence of intrinsic viscosity. Analysis of the measured viscosities shows that the accuracy of the proposed temperature model is higher than that of the existing temperature model.

Future Work

Enhanced Oil Recovery (EOR), is a technique that has been used to recover the remaining oil from the reservoirs after primary and secondary recovery methods. Some reservoirs are very complex and require advanced EOR techniques that containing new materials and additives in order to produce maximum oil in economic and environmentally friendly manners. Because of EOR techniques, in this work previous and current challenges have been discussed, and suggested some future opportunities. This work comprises the key factors, such as; transport of Preformed Particle Gels (PPGs), Surface wettability and conformance control that affect the efficiency of PPGs. The conduits, fractures, fracture-like features and high permeability streaks are the big challenges for EOR, as they may cause early water breakthrough and undesirable water channeling. Hence, the use of PPGs is one of the exclusive commercial gel inventions, which not only increases the oil production but also decreases the water cut during the oil production. Moreover, different studies regarding PPG, surfactants, and Silica nanoparticle applications, such as the effect of salinity, particle size, swelling ratio, gel strength, wettability, and adsorption were also discussed. Future work is required in order to overcome the conformance problems and increase the oil recovery.
