Abstract: A gas compression system including a body of fluid and a down pipe. A first end of the down pipe is positioned to receive a fluid from a source above a surface of the body of fluid and a second end is positioned at a lower level of the body of fluid. A gas inlet is coupled to the down pipe, above the surface of the body of fluid for mixing a gas to be compressed with the fluid from the source to form a mixture. A chamber is positioned at the lower level of the body of fluid and coupled to the second end of the down pipe for receiving the mixture and collecting a compressed gas therefrom. A conduit is coupled to the chamber for transferring the compressed gas therefrom.

Abstract: The invention relates to a motor-driven pump intended for the pumping of liquids and driven by a pressurized motive fluid. The motor-driven pump (1) has a rotary sleeve (12) mounted in line between two stationary connections (8, 10). Mounted on the periphery of this sleeve (12) are the blades of a turbine which surrounds the sleeve (12). Rotary pumping members (24) are fastened inside the sleeve (12). The motor-driven pump (1) of the invention is intended more particularly for use as a submerged pump, especially as a pump for dredging at great depth.

Abstract: A down hole pump operated by gas in which the fluid in the production conduit may first be gas lifted. The exhaust gas from the pump aerates the well fluids in the production conduit. The pump is controlled by a valve whose operation is in turn controlled by a pilot valve shiftable in response to operation of the pump.

Abstract: A fluid operated turbopump, suitable for use in an oil well pumping system, is structurally adapted as either a hydraulically insertable and removable unit or as a permanent attachment to a bottom hole tubing. The turbopump has axially spaced rotary driving and driven impellers operable for overbalancing columns of fluid which are separated by the well tubing wall, the overbalancing operation facilitating upward movement of fluid from a production zone to above ground storage. A tubular drive shaft which interconnects the impellers is utilized to convey fluid axially through one of the impellers.
