ABSTRACT:
A hydrocarbon producing well is worked over by wire line tools only to run a jet pump into the tubing string by perforating the tubing string and then isolating the perforation to direct power fluid injected down the annulus to pass into the power fluid inlet of the jet pump. Formation fluids delivered up the tubing string pass through the jet pump to the surface. The jet pump is placed in the well without tripping the tubing string and consequently without having to use a workover rig.
