Analytical and numerical solution of in situ polymer viscosity relationship with shear rate in porous media

(Text nur in Englisch verfügbar)


Polymer flooding is one of the EOR methods to improve oil displacement efficiency. However, the polymer solution is a complex fluid that exhibits a Non-Newtonian behavior and its flow behavior in porous media is still not fully understood. In practical applications, to estimate its effective viscosity, semi-empirical correlations are often used. These correlations describe the bulk and effective viscosity, which governed fluid and rock properties. This work's main objective is to develop an analytical and numerical solution of polymer flow behavior in porous media, specifically to relate the polymer viscosity obtained using rotational rheometer and micromodels.


Based on the above introduction, the proposed thesis should include the following:

  1. Semi-empirical correlations that relate the bulk and effective viscosity of polymer solutions.
  2. Pore- and continuum-scale simulation model of single-phase polymer flooding in micromodels.
