Abstract: A hydrocarbon producing well is pumped with a jet pump device. The jet pump is set below a packet in the well. A power fluid conduit leads from a location above the packer to the power fluid inlet of the jet pump. A produced fluids conduit leads from the outlet of the jet pump to a location above the packer. In one embodiment, power fluid is injected down the annulus and produced fluids go up the tubing. In a second embodiment, power fluid is injected down the tubing and produced fluids go up the annulus.

Abstract: A method of and apparatus for setting a mechanical liner hanger inside of a well conduit by right-hand or clockwise rotation and without downward movement. The hanger includes a mandrel having an annular cone and a lug. A movable cage telescopically and rotatably mounted on the mandrel includes slips, bow springs and a right-hand downwardly extending and downwardly directed spiral surface. A hanger is moved downhole with the lug engaging the cage holding the slips in the retracted position. When the setting location is reached the mandrel is lifted up releasing the cage, and the mandrel is rotated by right-hand rotation moving the lug against the downwardly directed surface of the cage for moving the slips upwardly onto the cone and expanding the slip into a setting engagement with the well conduit. The set hanger may be released by longitudinally raising the mandrel and lug.
