Abstract: A gas lift valve assembly includes a housing, a check valve, and a fluid flow barrier. The housing defines an inlet port, an outlet port, and a main flow passage providing fluid communication between the inlet port and the outlet port. The main flow passage has an upstream end and a downstream end. The check valve includes a sealing element disposed at the downstream end of the main flow passage, and a valve member configured to sealingly engage the sealing element. The valve member is movable between an open position in which fluid flow is permitted in a downstream direction, and a closed position in which the valve member inhibits fluid flow in an upstream direction. The fluid flow barrier is disposed within the main flow passage, and is configured to direct fluid flow away from the sealing element when the valve member is in the open position.

Abstract: A downhole power generation includes a power generation module for providing power to a load. A turbine is driven by flow of a downhole fluid to rotate. A generator is coupled with the turbine for converting rotational energy from the turbine to electrical energy, and an AC-DC rectifier is coupled with the generator for converting an alternating voltage from the generator to a direct voltage. A power conversion circuit couples the AC-DC rectifier with the load. The power conversion circuit is configured for providing a first power to the load when the load is in a working mode and providing a second power to the load when the load is in a non-working mode. The second power is less than the first power. A downhole power generation method is also disclosed.

Abstract: A downhole power generation system is disclosed, which includes a turbine generator system. The turbine generator system includes a turbine, a generator coupled with the turbine and having an AC-DC rectifier, and an optimized power control unit. The turbine is driven by flow of a downhole fluid to rotate. The generator converts rotational energy from the turbine to electrical energy and outputting a direct current voltage. The turbine generator system is coupled to a load via the optimized power control unit. The optimized power control unit controls to regulate an output voltage of the generator and provides a regulated output voltage to the load so that the turbine generator system has an optimized power output. An optimized power control method for a downhole power generation system is also disclosed.

Abstract: A system includes a casing-liner, a first downhole separator, a production pump, and a second downhole separator disposed within a wellbore casing disposed in a wellbore. An annular disposal zone is defined between the casing-liner and the wellbore casing. First downhole separator is configured to receive a production fluid from a production zone and generate a hydrocarbon rich stream and a water stream including a solid medium. Production pump is configured to pump the hydrocarbon rich stream from the first downhole separator to a surface unit. Second downhole separator is configured to receive the water stream including the solid medium from the first downhole separator, separate the solid medium to generate a separated water stream, and dispose the solid medium to the annular disposal zone. The system further includes a tube configured to dispose the separated water stream from the second downhole separator to a water disposal zone in wellbore.

Abstract: A pump for pumping a multiphase fluid includes a housing and a rotor with an outer surface. A plurality of inducer vanes are attached to the rotor hub, each having a leading edge and a trailing edge where the leading edge of one inducer vane overlaps the trailing edge of an adjacent inducer vane by a first overlap angle. A plurality of impeller vanes are also attached to the hub. The impeller vanes each have a leading edge and a trailing edge where the leading edge of one impeller vane overlaps the trailing edge of an adjacent impeller vane by a second overlap angle larger than the first overlap angle. The pump includes a rotor flow channel extending between the hub outer surface and the housing inner surface. The rotor flow channel has an inlet area and an outlet area, whereby the outlet area is smaller than the inlet area.
