Abstract: Well apparatus is disclosed in which a well tool connected to a landing tool is lowered within a well conduit by means of a wire line running tool which, when the landing tool is so lowered, may be manipulated in order to cause locking means carried by the landing tool to be locked with a locking groove of the well conduit, and which when the landing tool is so locked, may be released therefrom for retrieval from the well conduit. The landing tool carries keys which may be landed and locked within a selected one of a plurality vertically spaced landing nipples of the conduit each of which has a cylindrical bore and a groove having an upwardly facing seat thereabout on which the key may be landed when spring pressed outwardly into the groove.

Abstract: There is disclosed well apparatus including a wire line running tool assembly on which a well tool may be lowered into a well conduit, and then locked within the well conduit, and released from the assembly, when it is so locked, in response to manipulation of the wire line, whereby the assembly may be retrieved.

Abstract: These are disclosed three embodiments of a wire line tool for use in running and/or pulling a well tool within a well bore. In each embodiment, latches are carried about a body of the wire line tool and yieldably urged from inner positions, in which their outer ends are adapted to move into the well tool, to outer positions in which their outer ends extend into a groove in the well tool when opposite thereto. The wire line tool may be latched to the well tool at the surface for the purpose of running it into the well tool, or lowered into a well bore and latched to a well tool therein for the purpose of pulling the well tool. The latches are forced inwardly to remove their outer ends from the groove, and then retained against outward movement, in response to downward jarring of the body and subsequent lifting of the body with the wire line to permit the wire line tool to be retrieved from the well tool following running of the well tool into the well bore.
