HIGH ENERGY EFFICIENCY WITH EQUAL CATALOGUE VALUES, THE PERFORMANCE BASED ON REAL OIL POOL FLUID IS 2-9% HIGHER

EFFICIENCY IN RELATIONSHIPS

Use of low-adhesive ESPs allows reducing unit costs for energy consumption in comparison with ESPs with solid metal working parts:


1. Up to 20% due to less degradation of efficiency factor in time; degradation of efficiency factor occurs because flowing channels are obstructed with salts, asphaltene-resin-paraffin deposits, and non-abrasive mechanical impurities (in wells with abnormal operating conditions – with salt deposition, asphaltene-resin-paraffin deposition, and obstruction with non-abrasive mechanical impurities).

2. Up to 10% due to higher efficiency factor during lifting of formation fluid (in wells with viscosity at a pump intake from 10 to 40 cSt).

3. Up to 30% because dispersing stages of gas-resistant low-adhesive ESPs create gaslift effect (in wells with increased gas factor in comparison with using of gas separator)

4. Up to 15% due to less friction wear and less friction forces (because of less weight – in 2.5 times, and impeller balance) in radial friction couples (in non-abrasive wells with high water cut).
