Abstract: A running tool useful for installing lock mandrels and other subsurface wireline tools in a well bore, the running tool comprising top sub (12), retainer sleeve (14), bottom setting sleeve (16), core (18), insertion sleeve (44) and lockout sleeve (66). Running tool (10) is adapted to set lock mandrel (22) in landing nipple (60) and thereafter be released by jarring up to disengage lock retainer lug (28) from recess (30) in lock mandrel (22) and to disengage locking sleeve lug (32) from recess (34) in locking sleeve (36). Outwardly biased leaf spring (108) and latching lug (112) are provided to lock running tool (10A) in a fully released position. Emergency shear screws (68) and lockout lugs (90) are provided to permit withdrawal of running tool (10) and lock mandreal (22) from the well bore in case of a misrun.

Abstract: A connector assembly adapted to quickly connect and disconnect tools and stem sections in wireline tool strings. Connector assembly (10) comprises box end (12) and pin end (14) adapted to be slidably engaged and locked by rotating either end 90.degree. relative to the other in either direction. Connector assembly (10) is released by the direct application of manual force to ears (48, 50) of locking plate (38) accessible in flutes (26, 27) of box end (12). Once the locking plate is retracted, pin end (14) is rotated 90.degree. in either direction relative to box end (12) and then withdrawn axially from box end (12). Flats (130, 131) are provided on box end (126) and pin end (128) to indicate relative rotational alignment. Disclosed also are provisions for limiting the rotation of axially spaced lugs (138, 140) before the lugs are axially aligned with annular channels (142, 144).

Abstract: Disclosed are selective and no-go systems for injecting fluids in a well and a system for orienting a tool in a landing nipple in a well conduit, which is utilized in the selective set injection system. Each injection system is comprised of a land nipple, an injection mandrel having openings for flow and an orientor. The landing nipples have wall openings for flow and orienting means which are engaged by the mandrel orientor as the mandrel is lowered into the landing nipple, orienting the mandrel and aligning the mandrel flow openings with the nipple flow openings. There are orifices in the flow openings in both mandrels to control injected flow through the mandrel. The system for orienting a tool in a landing nipple has an orientor attachable to a well tool. This orientor and the selective orientor have lugs which engage an orienting sleeve in the nipple and are guided into slots when lowered into the sleeve.
