Upwing Magnetic Drive System
The electrical submersible pump (ESP) has been around for many decades. Although significant advancements have been made and continuous improvements at the component level are still underway, they will have a minor effect on the reliability of the overall ESP system due to the same failure modes adversely affecting the unchanged ESP architecture. As a result, recent ESP innovations have been focused on improving retrievability by devising alternative deployment means versus addressing reliability in order to gain higher ESP availability.
The alternative deployment methods developed to date should reduce operational costs, however the actual initial and operational costs of alternative deployed units are much higher than originally envisioned. This is due to the higher initial capital costs, the required unique changes to the well head and well site equipment, and the required specially trained personnel to deploy the complex ESP system, which is inherently low in reliability from the start.
With its core competence in permanent magnet (PM) motors, magnetic bearings, and magnetic fields, Upwing Energy is taking a completely new approach toward making electric submersible pumps (ESPs) more reliable and retrievable by introducing a disruptive design topology using proven technologies called the Upwing Magnetic Drive System™ (MDS).

Highly Reliable and Retrievable Design Topology
The number one cause of ESP failures is the electrical system—the cable, penetrator and motor. Upwing is eliminating this failure mode by hermetically isolating all electrical components from the hostile production fluids by placing them in the annulus of the well as a part of a well’s permanent completion.
The remaining mechanical components, such as the pump, thrust bearing, and Inconel sleeved motor rotor are placed on a retrievable string inside the well tubing.
The patent-pending MDS utilizes Upwing’s magnetic technologies to drive and levitate the rotor on the retrievable string from the permanent completion without the need for mechanical and electrical connections between the retrievable string and the permanent completion. Fluids are produced through and around the motor rotor.
Removing the most complex and unreliable component- the “protector” - from of the ESP system not only enhances the reliability, but also reduces the part count of conventional ESP systems.
Upwing’s proprietary technologies have been proven to be highly reliable and efficient by Upwing’s parent company Calnetix technologies in a wide range of applications and industries globally. They are also being utilized in Upwing’s Subsurface Compressor System™ (SCS) products for the artificial lift of natural gas.
