Slim-line ESP systems

Unique equipment for application in casings 4’’and 4½’’ (102, 114 mm)

Capabilities

Starting up of idle wells, exploration and

wells after casing repaire

ESP operation in highly deviated wells with zenith angle of

90˚ (horizontal wells)

Application in dual ESP systems for multi-zone production and bypass systems (Y-tool)

Drawdown in side track wells for effective oil production

At present many oil producing companies drill side track wells to sustain and increase oil production plans and also reduce capital investments in new wells. The experience of realization of this method proves technical and economical benefits in comparison with drilling of new wells due to lower costs for drilling and ability of using the existing communication, collection and transportation system of oil and gas in the field. Diameter of side track wells allows operation of ESP systems of 319 (81 mm) series and smaller ESPs, for example of 272 (69 mm) series.

Due to low efficiency of asynchronous motors in slim-line ESP systems permanent magnet motors (PMM) of 319 series with efficiency 88.6% are applied.

The 319 series pumps perform rated capacities 189–2264 bpd (30–360 m3/day), efficiency 48–64%, maximal head 11484 ft (3500 m) at rotation

frequency from 2590 to 6000 rpm. Powder metallurgy is used for manufacture of stages that is why better geometry accuracy

and improved operating performances with gas liquid mixture are observed. In wells with high sand production and/or gassy wells ESP systems

can incorporate appropriate intake devices.

esp of 272 series (69 mm)

offset module was designed to transfer torque between two out-of-line shafts, i.e. axes of motor and pump shafts are parallel but do not coincide with each other and have certain distance between them. MLE is placed in the shade of the motor that makes the diameter of ESP system smaller.
