Characteristics Analysis of Linear Submersible Electric Motors for Oil Production

2020 Russian Workshop on Power Engineering and Automation of Metallurgy Industry: Research & Practice (PEAMI), 2020
At the present time in the Russian Federation there are many low-rate wells with high-viscosity production and great depth of formation. Linear submersible motor driven plunger pumps are used to operate such deep wells with low flow rates. Submersible pumping units with linear electric motor are produced by several enterprises.

Determination of the electromagnetic parameters of submersible electric motors of electric centrifugal pumps installations

2016 Dynamics of Systems, Mechanisms and Machines (Dynamics), 2016
The article provides a method for the determination of electromagnetic parameters of asynchronous submersible electric motors (SEM) on the damping curve of the constant current recorded from a stationary rotor. The method is suitable for using both as in terms of electro-repair shops as directly on the surface of the multiple well platforms. The method

A novel sensorless IPM motor drive for electric submersible pumps

2017 IEEE International Electric Machines and Drives Conference (IEMDC), 2017
Electric submersible pumps (ESPs) are widely deployed for oil and gas production from deep downhole reservoirs. ESPs are located inside a well from hundreds to several thousands of feet below the surface. A variable speed drive (VSD) is situated on the surface platform, and power is supplied to the ESP from the VSD through long downhole cables that run

Evaluation of Electric Motors for the Reynolds Aluminum Deep Submersible

SAE Technical Paper Series, 1965
<div class="htmlview paragraph">With the advent of new interest in hydrospace, the manned, deep submersible has achieved a prominent place in oceanography and ocean engineering. Man-rated vessels capable of descending thousands of feet into the ocean have to be carefully evaluated.

Coupled Field Analysis Needs in the Design of Submersible Electric Motors

2007 IEEE Electric Ship Technologies Symposium, 2007
The design optimization of permanent magnet synchronous motors has long been a topic of major interest due to the widespread industrial use of such machines. Although there are a number of commercially available design tools to aid in such a task, the application specific nature of submersible motors has prompted the current interest.

Validation of Heat Transfer Performance of Electrical Submersible Motor Using CFD

ASME 2010 3rd Joint US-European Fluids Engineering Summer Meeting: Volume 1, Symposia – Parts A, B, and C, 2010
In oil field applications, the Electrical Submersible Pumping (ESP) unit (comprised of multistage pump, seal and motor) is placed inside a wellbore to provide necessary energy to lift reservoir fluids from the formation to the surface when the energy in the reservoir is not sufficient to lift the fluid to the surface.
