Detailed description

Downhole rotating tools have a significant number of radial bearings for supporting the rotor; having over 100 radial bearings in one tool is not uncommon. These mechanical sleeve bearings require active lubrication, which can be the production oil, water or an isolated lubrication supply, to operate for extended periods of time. Transient conditions, such as gas lock and contaminates in the fluid, can significantly impact conventional mechanical radial sleeve bearing performance and operating life. In a downhole compressor application where the speeds are 10 times the speed of conventional downhole pump systems and no fluid is available, a non-contacting high-speed bearing system is an enabling component, since conventional bearings are not able to have an economically viable life.

To address reliability, availability and cost, Upwing has developed a unique passive magnetic radial bearing. Upwing’s Passive Magnetic Bearing™ (PMB) does not require any controllers on the topside.
