ABSTRACT:
A down the hole product flow jet pump with a reverse flow removable injection nozzle that can be in the form of an orifice member placed in a plug or a one piece orifice and plug member that is moveable up and down the pumping fluid line dependent on the direction of fluid flow and/or non-flow in the line. The jet pump includes a check valve that opens for inflow of product from the well only when a drawing vacuum is created in the jet pump vacuum chamber so normal pumping flow can be stopped and reversed with the check valve closing when pumping flow stops and remaining closed during reverse flow in the system. A trap is provided at the wellhead into which the injection nozzle is floated with reverse flow of pumping fluid in the system. The injection nozzle is removable from the trap for servicing or replacement by insertion in the trap and then, with the trap opened, permitted to float down or be pumped down to seat in the jet pump housing on location down the hole.
