Abstract: A lubrication technique for one or more components used in the production of subterranean fluids. The technique comprises the separation of particulates from a produced fluid having lubricating ability. Following separation of the particulate matter, the lubricating fluid is directed to specific areas, such as bearing surfaces within a submersible pump, to facilitate continued operation of the overall system.

Abstract: A system for separating gas from a produced fluid. The system comprises a bottom intake completion utilized in a subterranean location. The system utilizes a gas handling system that separates a gaseous component from a fluid. The gas is vented to a separate flow path, while the fluid having a lower gas content is produced to a desired location.

Abstract: A technique for facilitating the movement of multi-phase fluids. The technique utilizes a compressor pump and a production pump. The compressor pump compresses a fluid to remove vapor phase and then discharges the pressurized fluid to a production pump. The production pump produces the pressurized fluid to a desired location with greater efficiency due to reduction of the vapor phase.

Abstract: A downhole pumping system for recovering liquids and gas, comprising a first centrifugal pump having internal features for mixing introduced gas into introduced liquids, and a second centrifugal pump having an intake in fluid communication with a discharge of the first centrifugal pump. In one prattled embodiment the internal features for mixing comprise improved impellers having a balance hole that extends through an upper surface of the impeller body into each of a plurality of internal flow chambers, and an additional passage in at least a plurality of the flow chambers. The additional passages cause some fluid to be recirculated in a manner that causes introduced gas to be mixed into the liquids, thereby increasing the pump's gas volume recovery ability.
