Abstract
An oil filter can include porous material that acts to filter solid particulate matter from motor oil, that forms a chamber and that defines a central bore for receipt of a drive shaft of an electric motor forming part of a downhole device; and, disposed in at least a portion of the chamber, sorbent for removing aqueous liquids from the motor oil. A downhole device may be an electric submersible pump.

An oil filter comprising:
- porous material that acts to filter solid particulate matter from motor oil, that forms a chamber and that defines a central bore for receipt of a drive shaft of an electric motor forming part of a downhole device;
- and,
- disposed in at least a portion of the chamber, sorbent for removing aqueous liquids from the motor oil.
A motor for a downhole device comprising a motor housing containing a stator fixed to the housing, a rotor mounted on a drive shaft in the housing, and an oil filter mounted in the housing wherein the oil filter comprises:
- porous material that acts to filter solid particulate matter from motor oil, that forms a chamber and that defines a central bore for receipt of the drive shaft;
- and,
- disposed in at least a portion of the chamber, sorbent for removing aqueous liquids from the motor oil.
An electric submersible pump comprising:
- a shaft;
- an electric motor operatively coupled to the shaft;
- a pump section operatively coupled to the shaft;
- and
- an oil filter that comprises porous material that acts to filter solid particulate matter from motor oil, that forms a chamber and that defines a central bore for receipt of the drive shaft and, disposed in at least a portion of the chamber, sorbent for removing aqueous liquids from the motor oil.
