Calnetix and has filed its own system-level and application-related
patents for downhole rotating devices. Upwing now holds
23 U.S. patents and has filed 47 U.S. and 28 foreign patent
applications to date. Its headquarters, engineering and manufacturing
facility is co-located with parent company Calnetix on
a seven-acre campus in Cerritos, California where the patent
wall shown above is located.
The SCS is a highspeed
downhole
compressor system
driven by a magnetically
levitated
permanent magnet
motor. The highspeed
permanent
magnet motor's
rugged, compact design
delivers higher
energy density and
lower heat dissipation
to provide much
greater efficiency
Upwing's SCS
than standard electric motors, says the company. The entire
motor is hermetically sealed to isolate electrical components
from hostile downhole fluids.
Magnetic drive system for Deepstar project
In the DeepStar program, Upwing and its project partner
Mitsubishi Heavy Industries (MHI) recently were awarded the
next phase of the Magnetic Drive System project by the global
offshore research and development consortium. Following
their completion of a design study last year, the new phase will
include the design, build and test of enabling technologies that
are the backbone of Upwing's MDS concept for
a reliable and retrievable electric submersible
pump.
" The innovative MDS topology built on advanced
magnetic technologies will significantly increase
production uptime while decreasing the total
cost of ownership by 75 percent in deepwater
offshore applications, " said Artinian. DeepStar
is a joint industry technology development program.
Members include Shell, Total, CNOOC,
Anadarko, Equinor, ExxonMobil, JX Nippon,
Chevron, Petrobras and Woodside.
Upwing will design, fabricate and test a fullscale
passive radial bearing assembly as well
as a magnetic vibration and temperature sensor
system to be utilized between the pump stages
and motor in the MDS. Upwing and MHI engineers
planned to begin work on Phase II in June
and are scheduled to complete the experimental
prototype, including component testing, by May
2021.
Robust magnetic designs inside
Upwing's artificial lift technologies are bringing
reliability to downhole rotating devices by leveraging
permanent magnet motors and applying
magnetic fields to the architecture of its tools.
All of its innovative technologies are proprietary
and patented or patent pending, says the company,
which has provided the following details
about them.

The magnetic coupling transmits torque from the motor to the
compressor without a mechanical shaft, which eliminates the
need for a rotary seal, pressure-compensating chambers and
dielectric oil. The active magnetic bearing provides support to
the thrust loads in the compressor. With no physical contact
and no lubrication needed, the bearing delivers extensive operational
life with zero friction. Passive magnetic bearings provide
radial support for the high-speed, rotating components.
