Wise Beyond Our Years
Upwing Energy is an innovative offshoot of parent company Calnetix Technologies, formed to focus on the production of hydrocarbons. Calnetix is a recognized industry leader in high-speed systems, supplying high-speed permanent magnet motors and generators, magnetic bearings and variable speed drives (VSDs) over the past two decades to a wide variety of industries throughout the world. The company’s product portfolio includes electric drive systems for offshore and subsea oil and gas applications.
Getting an initial kick-start from Calnetix and drawing on Calnetix’s knowledge and expertise has enabled us to prove the Subsurface Compressor concept and accelerate the development of our technology, tool and process innovations.
All of Upwing’s innovative technologies are proprietary and patented or patent pending.
Active Magnetic Thrust Bearings
Our proprietary active bearing system supports hydraulic section thrust loads without any physical contact or lubrication, delivering unlimited bearing life. Magnetic bearing controllers located on the surface provide real time information on thrust loads from the compressor to enable system diagnostic and prognostic capabilities.
Passive Magnetic Radial Bearings
Our proprietary magnetic radial bearing system supports high-speed rotating components radially without any physical contact or lubrication, delivering unlimited bearing life. Smart damping without the need of active controls improves system stability by minimizing the vibrations of the motors and compressors.
Hermetically Sealed High Speed PM Motors
In comparison to other types of motors used downhole, Upwing Energy’s permanent magnet (PM) motors enable a shorter tool length due to their higher energy density and lower heat dissipation from higher efficiency levels. Upwing’s novel, completely canned motor system, including both the rotor and stator components, isolates the failure-prone electrical system from hostile downhole fluids.
Our proprietary hybrid multiphase compressor system can operate in highly corrosive and erosive streams, allowing it to be utilized in wider range of wells. The unique compressor technology decreases the bottom hole flowing pressure dynamically at the intake of the compressor and boosts the pressure and velocity at the discharge to carry liquids uphole.
Upwing’s novel “protector-less” design is enabled by transmitting the torque from the hermetically sealed motor to the compressor without a mechanical shaft. It is scalable for the requirements of different types of gas wells.
Sensorless Long Step-Out Variable Speed Drives (VSDs)
Upwing Energy's topside sensorless VSDs are optimized specifically for PM motors, allowing for higher levels of efficiency and a wider operating range. The compact designs of the VSDs with bearing and system level controls provides a smaller footprint for both onshore and offshore operations.
The SCS system will autonomously optimize its performance and reliability in-situ without the delay of decision-making and manual control by personnel. All information will be linked to form a combined intelligent system control to optimize the system under external disturbances, conduct diagnostics and prognostics of components, and characterize the reservoir.
Upwing Tools and Processes
We have developed in-house modeling tools to predict wellbore dynamics and reservoir response to the Subsurface Compressor System. Additional in-house modeling tools optimize the performance of the compressor, VSD and long electrical cabling under varying production conditions. The combination of these tools ensures that maximum production is achieved 24/7.
Deployment and Intervention Methods
Our Subsurface Compressor System is deployable with existing intervention techniques, including tubing, rod and wire-line deployment methods.
