Annotation:

The article presents the calculations and results of using the refined inflow model for high-viscous oil fields, taking into account the non-Newtonian properties of the reservoir fluid. The rationale for the need to take into account the change in oil viscosity during the filtration process is provided. Based on the calculations, a possible error in predicting well operation parameters associated with use of viscosity parameter as a constant value is shown.
