Recent years there is trend of oil production increase from the wells with abnormal operating conditions. One of the complicated factors is elevated viscosity of the oil well production. Selection of the high-performance equipment for the work in such conditions is nowadays very relevant. The purpose of this research is a comparison of work of different construction ESP stages on the viscous fluids.

Tests of work of Different ESP Stages were hold on the experimental bedstead of Oil Field Development and Exploitation Department of Gubkin University. Tested ESP Sections are shown in Figure 1.

The following ESP stages were used as a subject for comparison: production stage VNN5-125, production stage VNN5-125 with bored impeller blades, and new construction stage with open-type impeller, which was developed at the Oil Field Development and Exploitation Department of Gubkin University.
