An electric machine is configured to be positioned within a wellbore. The electric machine enclosed within a housing isolates the electric machine from fluids within the wellbore. A first lubrication circuit includes a lubrication reservoir within the housing. The lubrication reservoir is fluidically connected to the electric machine. The first lubrication circuit is configured to provide lubrication to a bearing within the electric machine. A fluid rotor is configured to move or be moved by a fluid within the wellbore. A magnetic coupling couples the fluid rotor and a rotor of the electric machine to rotate in unison. A second lubrication circuit is configured to provide lubrication to a bearing supporting the fluid rotor.

Downhole lubrication system

A parameter of a magnetic bearing supporting a rotor in operation within a stator of the downhole-type rotating machine is measured. A speed of the rotor is controlled based on the measured parameter.

Controlling downhole-type rotating machines

Lubricating downhole rotating machine

An electric stator surrounds an electric rotor. A magnetic coupling is attached to an end of the electric rotor. The magnetic coupling is configured to transmit rotational force to or from a separate rotational device. A housing surrounds and isolates the electrical rotor, the electric stator, and a portion of the magnetic coupling from a wellbore fluid. A pressure within the housing is lower than a pressure within a wellbore environment.

Isolating a downhole-type electric machine

A gas flow velocity within a horizontal wellbore section is increased by a velocity string and a downhole-type compressor. A pressure within the horizontal wellbore section is decreased by a downhole-type compressor located within a vertical wellbore section fluidically connected to the horizontal wellbore section. Liquid build-up within the horizontal wellbore section is decreased in response to the increased gas flow velocity and the decreased pressure.
