ABSTRACT:
An device for use down-hole in an oil well for inducing heavy crude oil to flow into the inlet of a centrifugal pump by creating a positive pressure on the bottom inlet of the pump. The device inserts into the down-hole equipment string between the gas separator and the centrifugal pump. The device consists of an auger that attaches to and rotates with the shaft of an electric down-hole motor and a housing that surrounds the auger. The housing connects to the gas separator at the bottom end of the device and connects to the centrifugal pump at a top end of the device. The auger has tight clearance with the housing to enable the rotating auger to force the fluid upward within the housing as the auger rotates. The vanes of the auger are arranged so that the fluid is pushed with increasing pressure as it moves upward through the device to the centrifugal pump.
