ABSTRACT:
A jet pump system including a pump body having a nozzle carrier, a pump housing, and a cross-over housing connected in axially alignment. A flow discharge housing extends from the cross-over housing up to near the nozzle carrier. An injector nozzle having a cylindrical injection bore is axially directed into the discharge housing. A mixing tube is carried by the discharge housing which has a mixing bore in alignment with the injector bore. A funnel shaped flow intake throat merges through a mixing throat into the mixing bore. The cross-over housing is formed with large flow windows for discharge of the pumped mixed fluid through equally large windows, formed in a tubing seating sub into the annulus between the tubing and casing of a well. The assembly is equipped to be pumped down into operating position and pumped back to the earth's surface.
