Abstract: A self-cooling electric submersible pump having an integrated cooling system is provided. The cooling system is configured to cool and lubricate the electric motor section of the pump by expanding a compressed multi-component coolant fluid through flow channels within the motor. The coolant fluid contains a first fluid having a boiling point of at least 230° C. and a second fluid having a boiling point of less than 150° C. During pump operation the first fluid acts as a largely incompressible liquid and the second fluid behaves as a compressible gas. A compressor compresses the second fluid in the presence of the first fluid to produce a hot compressed coolant fluid from which heat is transferred to a production fluid being processed by the pump. The compressed coolant fluid is expanded through an orifice and into the motor flow channels, returning thereafter to the compressor.

Abstract: A cryogenic liquid storage system and method in which cryogenic liquid is stored within an active cryogenic liquid storage tank and one or more passive cryogenic liquid storage tanks. Headspace regions of the passive cryogenic liquid storage tanks are connected to the active cryogenic liquid storage tank and the active cryogenic liquid storage tank is refrigerated to collapse the headspace vapor within the active cryogenic liquid storage tank causing the flow of headspace vapor from the headspace regions of the passive cryogenic liquid storage tanks to the active cryogenic liquid storage tank. The increased head of liquid produces a pressure differential that drives liquid from the active cryogenic liquid storage tank back to the passive cryogenic liquid storage tanks.
