Abstract: A system for handling gas and liquid produced in a well comprises a centrifugal gas compressor 349 located within the well, a downhole electric motor 355 for rotating the gas compressor, a liquid pump 359 located in the well, and a processing system which controls the operations of at least one of the centrifugal gas compressor, the electric motor and the liquid pump. After compressing the gas, the centrifugal gas compressor delivers the gas to a selected gas delivery location. The liquid pump delivers the pumped liquid to a selected liquid delivery location. A gas separator (383, figure 3L) can also be located below the liquid pump, and controlled by the processor, for receiving liquid and gas from the well and delivering the separated gas and liquid to the compressor and pump respectively. A sensor member can monitor at least one wellbore condition, and communicate this data to the processing system.

Abstract: An improved electrical submersible pump is disclosed in which a processor downhole is utilized to monitor one or more subsurface conditions, to record data, and to alter at least one operating condition of the electrical submersible pump. Novel uses are described for downhole gas compression, the delivery of particulate matter to wellbore sites, and for the disposal of waste.

Abstract: The motor cooling and protection system has a shroud 36 concentrically disposed about a motor housing of a downhole motor. The shroud is sealed from well fluids in the well and defines and annular chamber between the motor housing and the shroud. A longitudinal annular baffle 38 is located in the chamber and partitions the chamber into two annular and concentric sub-chambers. The two sub-chambers have axially spaced apart communication openings 42a, 42b such that the two sub-chambers are in fluid communication with each other. A cooling fluid having high conductive heat transfer rates is located in the chamber for circulating between the two sub-chambers, through the communication openings, to facilitate and enhance the transfer of heat between the motor and the well fluids. An impeller driven from the electric motor may be provided to force circulate the fluid in the shroud.

Abstract: A gas compressor is employed downhole in a well for pressurizing formation gas. The gas compressor is driven by a downhole electrical motor. The downhole assembly also includes a pump. The pump might be located below the motor and driven by the same motor. In that event, the pump pumps liquid being produced by the formation downward to a liquid disposal formation. Also, the pump may pump the liquid to the surface, with the gas being delivered into a repressurizing zone.
